central air conditioning system

The Surprising Health Benefits of a Central Air Conditioning System

In American homes, you're more likely to find an air conditioning unit than a dining room. What was once considered a luxury is now a common feature of most houses in the US. 

A central air conditioning system helps regulate the temperature of your building, decrease humidity, and ward off the effects of high temperatures. It gives you comfort and relaxation year-round. 

The benefits of a central AC system go beyond mere comfort, though. They can also offer a range of surprising health benefits. Here are a few. 

You'll Sleep Better

We sleep better in cooler temperatures. This is because when we begin to feel tired, our body's natural temperature starts to drop. Stepping into a swelteringly hot room may block this process. 

A cooler room not only means that you'll be able to fall asleep faster, but it means you'll be able to sleep for longer. This is because your body's temperature begins to rise the closer you are to waking.

Some people can wake up during the night due to a rise in heat. A central air conditioning system will prevent this from happening by keeping your room cool all night long. 

Better sleep can lead to less stress, an increase in happiness, and a better immune system. And air conditioning can help you achieve all of this. 

Your Indoor Air Quality Will Improve

Indoor air quality has become a point of concern for many over recent years. 

Air quality will significantly increase with a central AC system. In your home, pollutants and chemicals are constantly building up inside. These irritants can become trapped in enclosed spaces and lead to respiratory problems, especially for people living with asthma.

Special filters in your air conditioning system work by removing dust, irritants, and harmful gasses from the environment and replacing them with cool and clean air.

The filter will also be able to remove pollen and dust mites from the air inside your home. 

The Humidity in Your Home Will be Regulated

Humidity in Visalia and Handford can fluctuate a lot depending on the season. Maintaining balance is key. 

Too much humidity can be harmful and lead to respiratory issues, but it also causes mold to grow in your house, which can lead to further breathing problems. 

On the other hand, low humidity can cause you health problems too. These include dry skin, dehydration, and a weakened immune system. 

Air conditioning systems will regulate the humidity in your home using evaporator coils that condense the water vapor from the air in your home, keeping humidity at manageable and safe levels. 

This will lead to a better immune system and increased respiratory health.

Want to start realizing these benefits today? The best thing you can do is keep your central air conditioning system in good check.

AC Problems: 4 Signs Your Air Conditioner Needs to Be Replaced

Did you know that 87% of American homes use air conditioning? But despite these numbers, it's amazing how many people don't know when to replace their units. In fact, many don't even recognize huge warning signs! By learning about these warning signs, you'll be able to tell when you need to ditch your old system and get a new one. In this article, we'll discuss 4 serious AC problems where you'll probably need to replace your unit.

1. It's Making Loud Noises

If your air conditioning is working correctly, it should be pretty silent, besides the blowing sound. So if there are any banging, clanking, or whining sounds coming from your AC, this should be cause for concern.

If you've already had your AC unit repaired multiple times and it's still making these loud noises, then it's high time you have it replaced.

2. You've Had to Make Multiple Repairs

On that note, if you keep having to dial a local HVAC professional in your area to come fix your unit, then it's time to rethink things. It's just not financially wise to keep making repairs when you can just make an investment in a newer unit. Units over a decade old need to be replaced anyway.

Not only is a new AC system going to need fewer repairs (maybe even none in the first few years), but it'll also save you some money. More modern technology means you'll purchase units that have better energy efficiency, which can be a huge help if you've noticed that your utility bills are sky-high in recent years.

3. There Are Strange Smells

Of course, your AC shouldn't emit any smells. So if you get a whiff of mold, mildew, sulfur (like rotten eggs), or even burning, then take these as serious signs.

You'll most likely need an AC replacement if you're experiencing these odors. This is especially true if you've been diligently following up with maintenance and you're still getting these smells.

4. Your House Doesn't Cool Evenly

Over time, AC units become less efficient. As a result, one room might be comfortably cool while the one next to it is stifling hot. In fact, some areas might even feel humid!

Again, if you've been getting regular maintenance on your AC system and this is still happening, then it's a huge red flag that it needs to be replaced. You might have issues with your equipment or the ductwork, so it's best to have a pro come pintpoint your issues.

Don't Ignore These AC Problems

If you run across any of the above AC problems, don't ignore them. Have an HVAC expert come and inspect it, then replace your AC if needed.

By taking prompt action, you'll ensure that your air conditioning will be working when you need it the most.

ac blowing hot air

Why is Your AC Blowing Hot Air? The Answer Explained

On average, a well-maintained air conditioner lasts anywhere from 12 to 17 years. If your AC is less than 10 years old and it's blowing hot air, the chances are high that it's NOT about to kick the bucket. Is your AC blowing hot air?

This quick guide will break down what could be causing it and what to do next.

Why Is My AC Blowing Hot Air?

There are many potential reasons for your California AC unit blowing hot air. Whether your AC unit is blowing hot air outside or inside, most of those issues are easy to fix.

Let's take a look at some of the causes for an AC blowing out hot air.

There's a Restriction in Airflow

If there's a restriction in airflow either to or from your AC, it means that there isn't enough air coming out of the vents in order to cool your home.

A compromised airflow can result in the compressor in the outside unit freezing up. What causes these issues? It could be that the air filter needs to be replaced or that your AC needs maintenance.

The Thermostat Isn't Correct

Sometimes an issue with the AC can be as simple as an incorrect setting on the thermostat.

Check and make sure that your thermostat isn't set to "heat." Someone could have bumped it or flipped the wrong switch. Check and see if it's set to "auto" or "on," too.

When an AC is set to "on," it'll blow warmer air out of the vents even when the outside AC unit isn't running. If you feel warmer air out of the vents, it could just be that the AC isn't cooling at that moment.

Low Refrigerant

Low refrigerant is another reason for AC blowing out hot air. Plus, if your AC has a worn service valve, poor assembly, or loose joints, it could be that you have overcharged or undercharged refrigerant.

Refrigerant is dangerous to try and handle on your own. If it's low or leaking, be sure to get a certified technician to come and check it out.

There's No Power

First, check the batteries and settings. Then, check that your AC has power by taking a look at the electrical panel.

If your AC demanded too much power, the circuit breaker might have shut off the power as a safety precaution. In California and other states with hot summers, it's not uncommon for AC to stop working due to too much demand for power.

Don't Panic if Your AC Is Blowing Hot Air

If you find that your AC is blowing hot air, don't fret. There are many simple issues that can cause warmer air to blow from your vents, all of which are easy fixes for a licensed HVAC technician.

If your Hanford home's AC is blowing hot air and you want to get to the bottom of it, contact us! We take pride in our communication, expertise, and money-back guarantee. We are here to help!

Central AC Troubleshooting: A Guide for New Homeowners


Hitting the beach on a hot summer day in California is truly living the dream.

The surf is perfect, the cooler is stocked and there's a perfect coastal breeze peeking through.

Picture leaving that scene to go home where your AC unit is uninterested in cooperating. Cooking lunch has now become the equivalent of standing on the literal equator.

Central AC troubleshooting plagues folks when transitioning from spring to summer. The need for cool air and less humidity takes over, and we'll stop at nothing to make sure we've got it.

If you're a new homeowner dabbling in HVAC maintenance, air conditioner repair is probably at the top of your priority list. And for a good reason.

Common Central AC Troubleshooting

Air filters help us breathe particulate-free oxygen in our homes.

Air filters help filter out pollen, dust, and other air pollutants that impact our air quality.

Folks with allergies and respiratory sensitivities can identify clean air from polluted air. Some have severe reactions to things like dander and allergens lingering in the air.

Air filters need to be changed throughout the year to ensure maximum air purity.

Like air filters, refrigerant plays an enormous role in keeping cool air moving through our homes. If your AC unit is low on refrigerant or has a leak, it can impact the level of cool air your AC unit can pump out. 

Refrigerant leaks can have harmful effects on our health. If you notice that your refrigerant is leaking, it’s important to reach out for support.

Having a professional with experience measures the resources needed to have a positive outcome and restore your AC unit to functional status.

Calling in the Big Leagues

As a new homeowner, there's an endless list of things that need your attention. From the clogged gutters to the moldy basement, we know your hands are full.

Like many preventative measures, yearly maintenance of your HVAC unit can extend the life of your unit, therefore putting money back into your pocket.

You wouldn’t let your car go without an oil change for three years. Like your prized vehicle, you want your air conditioning unit to live a long and happy life.

Having an AC professional diagnose and treat common HVAC issues can take unnecessary stress off your shoulders. Even if you're struggling to pick up some key signs about a leak or filter needs, your technician will be able to step in and lend support.

In 2019, air conditioner repair made up 24% of reported home maintenance repairs, only second to plumbing. With HVAC maintenance, the question is never if, but when your unit will need tending to.

4 Warning Signs You're in Need of an HVAC Repair

The average air conditioner will last between twelve and seventeen years. During this lifespan, your HVAC unit will likely need at least a few repairs to keep it running efficiently.

Although routine maintenance can help decrease the repairs needed and prolong the life of your AC unit, emergencies do pop up. But how do you know when you need HVAC repair? Continue reading to learn four warning signs you should call a technician in Hanford.

1. Unusual Noises

Your Hanford air conditioner will make some noises when it's turning off or on, as well as when it operates. If your HVAC unit suddenly starts making noises that are unusual for it, this is a warning sign it needs repair. Unusual noises may include squealing, grinding, or grating noises.

Unusual noises could indicate a part has become loose or broken inside of the unit. It could also mean other problems, which an HVAC technician can diagnose.

2. Strange or Foul Odors

Your air conditioner should never emit strange or foul odors. This indicates a serious problem that, in some cases, can even be threatening the health of your family. Anytime you smell strange odors coming from your HVAC unit, shut it off and call for assistance right away.

A smell like rotten eggs could indicate a natural gas leak in your heater. An electrical or burning smell may indicate the motor is no longer working properly or is overheating.

3. The Air Isn't Getting Cold

An air conditioner that isn't producing cold air isn't just annoying. This can also be a warning sign your unit requires HVAC repair.

Air that isn't getting cold may indicate the thermostat has stopped working correctly. Another reason for warm air coming out of an AC unit is a refrigerant leak. This latter part can be dangerous to the health of your family because refrigerant is a hazardous chemical.

4. Moisture or Leaking

There shouldn't be any significant moisture accumulating on or around your air conditioner. There should also never be any leaks. If you notice either of these issues, turn off the unit and call for HVAC repair as soon as possible.

Leaks can be refrigerant, which (as mentioned above) are very dangerous. Leaks could also indicate the unit's drain tube has become blocked, broken, or cracked. A certified HVAC technician can help you determine which is the issue.

More Questions About When HVAC Repair Is Necessary?

When an HVAC unit stops working the way it's supposed to, it can be a severe issue that interrupts your day-to-day life. The four things listed above are among the most significant warning signs you need repair, but they aren't the only ones. If you notice your unit isn't working as it should call a technician as soon as possible.

noisy air conditioner

This Is How to Quiet a Noisy Air Conditioner

In the United States, 89% of single-family homes have air conditioning, and nearly 90% of new homes are built with central air conditioning systems. This is an extremely high number when compared to continents, including Africa and South America. Despite your relief from the heat, a noisy air conditioner can still plague you at night.

Here are our favorite ways to quiet common ac noises.

Installing a Sound or Compressor Blanket

Installing a compressor blanket can be a very specific and effective way to reduce air conditioner noises. While its name may make you believe the blanket "compresses" sound so that you don't hear it, it actually refers to the compressor components within the air conditioner unit.

The full name of an abbreviated HVAC system is a heating, ventilation, and air conditioning system. The compressor of the system is in charge of the cooling section of the machine.

Long story short, the compressor is in charge of maintaining the various liquid and gaseous states of refrigerant liquid. If your AC is not working, your HVAC compressor could very likely be the reason why.

When the compressor is broken, it can, unfortunately, give off rattling, grinding, clinking sounds, and more. To a lesser degree, these sounds occur even when your system is working correctly, too!

Getting a noise blocker can be an efficient and inexpensive way to prevent noise if your home's temperature is consistent.

Consider AC System Size

Sometimes, your AC unit is simply loud. It doesn't matter what blanket you install; it doesn't matter how well it's working; it's still keeping you up at night and making it impossible for you to focus during the day.

Your HVAC unit might actually be too big for your floor plan or house size! If you're certain that your unit is providing you enough heat and cooling, it may be worth seeking an expert to see if a smaller, quieter unit could keep you just as comfortable.

There are many calculators that can help you in properly sizing an AC unit to your floor and house space. Using one of these digital tools is a great way to get started before receiving a quote from an installation company.

While reducing the size of your loud air conditioner may help tremendously, in some cases, it can't be done without making the system too weak to use. In these cases, moving the system to another location may be your best bet.

Noisy Air Conditioner Experts

Did you know that specific city and county permits are necessary to alter and replace air conditioners? Although it will cost money to hire an expert, oftentimes, hiring an HVAC installation and repair company is the fastest way to relieve your ears.

Here at Comfort Now, we offer large rebates for new system replacements and as little as $9.99 for diagnostic testing. We'll make sure your system is up and running as soon as possible and is headquartered in the Visalia, CA area. Call us today to address your noisy air conditioner.

5 Most Common HVAC Problems and Repairs

In 1902, Willis Carrier invented modern air conditioning. More than a century later, people still enjoy the comforts of HVAC. Despite immense technological progress, HVAC still occasionally has problems.

You can't avoid HVAC repairs. Be prepared for when then the five most common HVAC problems arise by reading on.

1. Central AC Doesn't Work

The central air conditioning not working is an all-too-common problem. Fortunately, there are some quick fixes.

Ensure the thermostat's set to cool and its temperature setting is at least three degrees below the ambient room temperature. Also, make sure the power's on.

You could try turning off the power to the air conditioner then removing the thermostat's body. Separate the body from the base and replace the batteries.

A last-ditch solution is checking the compressor's contactor and capacitor. It may be time to replace the capacitor.

2. AC Running But Not Cooling

Another of the most common HVAC issues is the air conditioner running but not cooling. Something could be limiting or blocking airflow. Look for dirty air filters that may be clogged by an accumulation of debris and dirt.

If that doesn't fix it, verify that the thermostat's working right. An electronic thermostat that doesn't display any information may have dead batteries or be worn out.

An alternative cause of the problem is low refrigerant (freon). It's often due to refrigerant leaks, in which case you should call one of the HVAC technicians in the Visalia or Hanford area.

3. Air Conditioner Doesn't Turn Off

Your air conditioning should turn off when the room temperature reaches the temperature that the thermostat's set at. If it doesn't, then there's a problem with the electrical system running the outside condensing unit or the thermostat itself.

You should probably replace your thermostat if it's blank or if the AC turns off when you turn the heat on. You probably don't need to replace your thermostat if it works with the furnace.

4. Air Handler Doesn’t Blow Air Right

Next, the air handler could fail to blow air properly. If that's the case, the indoor evaporator coil may be frozen or dirty.

Reduced airflow can make the coil freeze and thus block airflow. A dirty coil, dirty filters, broken fan motor, or dirty squirrel cage blower can all decrease airflow.

Simply replace the belt that connects your air handler's motor to the blower.

5. The AC Has a Water Leak

Air conditioners' condensation is water that needs to exit the air handler. Use a drain tube or plastic pipe to get the water out.

A condensate pump connects to a half-inch rubber or vinyl tube that goes to a drain outdoors. A drain tube goes outside and ends near the compressor, condensate pump, or floor drain.

Inevitable HVAC Repairs

Heating and air conditioning have come so far since their invention. A comfortably cooled (or heated) home is a 21st-century birthright in central California.

furnace noises

These Are the Common Furnace Noises You Need to Know

Even in Southern California, we rely on furnaces during chillier months. All furnaces make occasional noises. Sometimes those noises act as quiet background noise and comfort us when we sleep.

But, what about those furnace noises that sound different or suspicious? Certain furnace noises need immediate attention.

Keep reading to learn more about common furnace noises that you shouldn't ignore.

Normal Furnace Noises

You will notice some noise when you first turn on your furnace. Common furnace sounds are a pop or click as the furnace heats up. The furnace often settles into a dull hum.

The hum and click are often louder in older furnaces compared to newer ones. Annual tune-ups ensure your furnace will continue to run smoothly during colder California months.

Furnace Noises You Shouldn't Ignore

If your furnace is making noises that seem out of character, it can be a sign that your furnace needs repair.

Be aware of these noises that you should always pay attention to.

Loud Bang

If you hear a loud bang or pop come from your furnace, it is often the result of dirty burners. Gas builds up because dirty burners are difficult to ignite. When the burners eventually ignite, a loud bang occurs.

This sound is concerning because the situation could eventually cause a small explosion. It could also crack the heat exchanger which would require an expensive repair.


If a part has come loose or becomes worn out, you will often hear a squealing or whining sound.

A common issue is a loose blower belt or damaged blower motor. Other times, your furnace will squeal if the shaft bearings need lubricating.

Seek out maintenance right away if you hear squealing. Ignoring the problem will cause additional damage.

Loud Humming

Although dull humming is normal in most furnaces, be aware of loud humming. Older furnaces may have a louder transformer that causes the humming.

But, if the humming seems out of character, you may need to replace the fan or capacitor.


If you hear repeated clicking when you turn on your furnace, it could be one of many issues. It could be an issue with the thermostat. This is not a complicated issue to fix, but it should still be addressed with a technician.

A clicking noise can also indicate a broken flame sensor. There could also be a disconnect between the gas and the ignition.

Sometimes, a repeated clicking noise indicates a problem with the capacitor or fan.


A persistent rattling noise can indicate broken parts in the fan or motor. Sometimes, rattling sounds come from loose screws on the front panel. If this is the case, you can listen to figure out where the rattling is coming from.

Screws could also need tightening in the ductwork. Be sure to address rattling sounds right away. If the noise worsens, it could indicate a complete system failure.

Let Us Fix Your Furnace Problems

If you hear any of these concerning furnace noises, be sure to call Comfort Now for maintenance. Our skilled technicians will accurately diagnose and fix your problem.

5 Air Conditioning Problems That Happen More Often Than Not

More than 87% of American homes have some form of air conditioning. Many homes have central air, while others use alternatives like window units and portable air conditioners instead.

We rely on air conditioning to keep our homes cool and comfortable. That's why it's so frustrating when you have air conditioning problems.

Luckily, we've outlined the most common air conditioning issues and what they mean below. Plus, you'll learn some AC troubleshooting tips and when it's time to call a pro to handle your AC repair.

1. My AC Unit Is Blowing Hot Air

One of the most common air conditioning issues is when the unit blows hot air instead of cold. First, make sure your unit is set to AC and not heat, as this can happen.

If that's not the issue, you could have a low refrigerant or a dirty evaporator coil caused by a dirty air filter. Your outside unit could also have lost power due to a tripped circuit or blown fuse. If you still can't figure it out, call for repairs.

2. The AC Isn't Keeping Up with the Thermostat

If your AC isn't cooling your house to the temperature setting on your thermostat, debris like grass or plants might be blocking your outdoor unit. It could also be a leak in your air ducts.

It could even be an issue with your attic ventilation or a lack of insulation in your home. If you're not sure what the problem might be, find a local AC maintenance technician to investigate.

3. The AC Unit Won't Turn On

If your AC won't turn on, first check the batteries in your thermostat. If that's not the problem, make sure the thermostat is on and set to AC mode.

It could also be from a tripped circuit breaker or a blown fuse. Try resetting your circuit breaker or replacing the fuse.

4. My AC Unit Runs Constantly

If you've just had a new AC unit installed but it runs constantly, it could mean the unit isn't large enough.

If this is a new problem, it could point to an issue with the blower or fan. You might also have a clogged air filter, dirty condenser, or a thermostat issue. This can be a complicated problem to diagnose, so you may want to call in a technician.

5. The AC Makes Strange Noises

AC noises can point to a range of different problems, so decide what the noise sounds like. If it's hissing or buzzing, that could mean a refrigerant leak or an electrical problem.

If you're hearing banging or thumping, that's a sign of a blower or motor problem. If you hear screeching, you might have a problem with your fan motor or compressor. It's best to call a service technician before the problem gets worse.

Cleaning Furnace Burners: Keep Your Furnace Working Properly

To quote Game of Thrones, winter is coming. That means it's time for quality heating. Here in Visalia, CA, temperatures can drop to 38°F in winter.

If you've noticed your home is slow to heat up, that could point to an inefficient furnace.

Dust builds up throughout your home throughout the summer. Other allergens in the air can also build-up, along with condensation.

This buildup, when added to the dirt and soot from the previous winter, clogs the burners. They won't burn as efficiently as clean burners, meaning it costs more to warm your home.

Make cleaning gas furnace burners part of your regular maintenance regime. Next year, you'll have clean burners before you need them.

If you're keen to start cleaning furnace burners in your Visalia CA home, read on to learn how and why to do it.

1. Check the Burners are Clean

Before you dismantle the furnace, you can tell if your burners need to be cleaned at all. Look at the flames.

If they're even and blue, your burner is clean. Yellow flames mean the burners are dirty. The flames change color as they cope with debris or dust.

If you've got yellow flames, move onto step 2.

2. Check the Furnace Filter

Turn off your gas and electricity supply to the furnace before you start any maintenance.

Check the filter is clean before you start cleaning dirty furnace burners. The filter might be in the furnace itself. Otherwise, it'll be a grate in the floor or wall nearby.

Remove the filter and hold it up to a light source. Is the light shining through it? Your filter is fine and you can move onto step 3.

If the light can't get through, you need to change the filter. Replace the filter and move onto step 3.

3. Access the Burners

Take the front panel off the furnace. Your owner's manual will give specific instructions for your type of furnace.

You'll find the burners in a chamber above the blower. Take the burners out so you can clean them.

4. Cleaning Furnace Burners

Use the soft brush attachment on your vacuum to clean the burners. It'll remove dust or rust that has built up since the last clean.

You might find the dirt is too stubborn to remove. If so, tap the burners to help knock any debris loose. Vacuum around the blower too while you have the furnace open.

5. Reassemble the Furnace

Once they're clean, put the burners back in the furnace. Replace the front panel on the unit. It's now safe to turn the gas and electricity supply back on.

If your heaters are blowing cold air, check out our guide to diagnose the problem.

Enjoy a Warm Home

Now you know why cleaning furnace burners should be part of your annual maintenance. You also know how to do it so you can clean them yourself.

Yet you may still find issues with your furnace. It may need further repair, so you'll need professional help to diagnose the problem.

If you're in Hanford CA or Visalia CA, contact us today and we'll get your home toasty warm for the winter.
