air conditioning problems

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 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 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.

5 Common AC Installation Mistakes and How to Avoid Them

Your AC unit is essential for livability and comfort. In the US, nationwide AC installation costs now average between $8,000 and $15,000, a figure that is rising. That's why it is important that the technician who installs your AC gets it right the first time.

There are a number of common AC installation mistakes that poorly trained technicians can make. These mistakes can end up costing you time and money.

That's why being able to identify the mistakes before they happen is crucial. When you know the most common AC installation mistakes, you will be able to ensure that your technician gets it right the first time. Read on to find out what you need to be aware of when getting a new AC.

1. The Wrong Size AC

The most common mistake when installing AC is when a technician chooses the wrong sized unit for your home. There are various different unit sizes that a technician might recommend.

They might try and sell you the biggest unit they have, which will be more expensive. However, an oversized AC unit will fail to properly cool your home and may lead to some serious structural damage. Bigger is not always better when buying an AC unit.

2. Refrigerant Pipes Are Too Long

There are numerous locations for units in your home. No matter where you choose to put it, it is important that the refrigerant pipes that connect the indoor and outdoor units are kept as short as possible.

Pipes that are too long will make it impossible to complete the essential cooling cycle, leading to the overuse and breakdown of your AC system.

3. Incorrect Thermostat Placement

The thermostat of your AC has the role of regulating how much power your AC unit uses and how to keep indoor temperatures at optimal levels. When choosing where to place thermostats, it is important that it is placed somewhere that will not throw your AC unit out of whack.

Placing a thermostat near a heat source such as a radiator or light bulb is a big no-no, as this will prompt the AC to work overtime.

4. Poor Insulation

Providing adequate insulation is a vital part of any AC installation service. This could mean filling open areas of window units with insulation foam. It could mean installing the right size insulation ducts.

If your AC has poor insulation, then it may suffer from cold air leakage. This can lead not only to insufficient cooling but also a complete breakdown of your AC system.

5. Badly Designed Drainage Systems

AC systems tend to create a lot of wastewater. This must be safely drained away if you do not want any problems. Improperly installed drainage systems will lead to a buildup of water in and around your AC unit.

This will not only cause unpleasant leaks in your home, but it can also lead to severe damage to your AC. What's more, poor drainage can cause water to freeze in the pipes, destroying your AC completely.

Call a Professional to Avoid AC Installation Mistakes

AC installation mistakes may be common, but they are by no means unavoidable. Never be afraid to ask your technician questions about the installation process and let them know that you are clued up.

The best thing you can do is to call an installation expert with years of experience, who will be sure to avoid any mistakes. For this, do not hesitate to call our professional AC installation team today to arrange an error-free AC experience.


why is the heater blowing cold air

Why Is the Heater Blowing Cold Air? 5 Likely Reasons Your Home Isn't Warming Up

Heat in your home during the colder months is essential. It can mean the difference between a comfortable environment and one that is completely inhospitable.

In order to ensure that you are comfortable, you probably depend on your heater a lot. However, often things can and do go wrong with it. Your heater may start blowing only cold air.

When this happens you will probably want to know, why is the heater blowing cold air? In order to troubleshoot this problem, you will need some guidance. Here is a look at what you need to know.

1. Why is the Heater Blowing Cold Air?

The fact is that there are several reasons why the heater could be blowing cold air. One of the first things you should check is your breaker. Often the breaker will trip and prevent the heater from functioning properly.

If you have a gas furnace this is still relevant to you because gas furnaces usually have an electric starter. This electric starter is used to ignite the furnace.

2. Check Your Flame Sensor

Your flame sensor may be dirty. The flame sensor tells the gas heating unit to turn on. It also tells warm air to cycle through the heater.

When the sensor is dirty it will often not recognize if your burners are turned on. A dirty sensor can prevent ignition as well. The end result is that cold air is passed through the heater.

3. Your Heat Pump May Be Covered

Another common reason why your heater may not be working is that your heat pump may have been covered in snow.

The heat pump can also malfunction if it is low in refrigerant or has bad valves. Check your metering device as well. If any of these are bad you will need to get professional help.

4. Check the Pilot Light

If the gas supply to the furnace is interrupted then the pilot light on the furnace will go out. When this happens this will make the heater blow cold air.

Check the manual that came with the furnace, it will usually contain instructions on how to relight your furnace. If after you have re-lit your furnace it will not stay lit then you need professional help.

5. Is Your Thermostat Working?

If you keep your thermostat in the on position instead of the auto position the furnace will run continually.

This means that the furnace will be running even when it's not on the heat cycle. All you need to do is adjust the thermostat. Check the thermostat batteries as well to make sure they are functioning correctly.

Get Warmed Up

You now know the answer to, why is the heater blowing cold air? If you find this happening be sure to troubleshoot your breaker, flame sensor, heat pump, pilot light, and thermostat.

More than likely something has gone wrong with one or more of them. Often you can fix the issue yourself.

If you find that you cannot fix it yourself then you can hire professionals. When you need professional help do not hesitate to contact us.


fan vs. ac

Ceiling Fan vs. AC: A Comparison of Power, Price, and Payoff

Did you know that 90% of American households have AC units installed?

As the summer rolls on and the temperatures continue to rise, AC could seem to be your best option for cooling your house.

However, more and more people are starting to see the value of installing fan systems to cool their homes.

Where do you stand in the fan vs. ac debate? What are the advantages of each system?

Why not read our in-depth article to find out more

The Advantages of Fan Systems

If you are interested in lowering your carbon footprint, then a fan system could be for you. The fan unit itself will produce or use no harmful gases or pollutants whatsoever. This means that you will have a more environmentally friendly air movement system.

A fan system is a very simple system. As mentioned it does not require any chemicals. This means that it does not require and piping or invasive installation before you can switch it on. The operating costs are generally low and it will require little maintenance over its long lifespan.

Fan systems can be portable or fixed. You can move a portable fan system from room to room as you need to. If you stop using a room, you can remove the fan from the room for free. This is not so easy with an AC System.

Fan systems definitely have their advantages, however they do lack some significant functionality. What are these?

The Advantages of AC Systems

While fan systems do have their advantages, we have to accept that actually, they only move air in the room. They do not actually have any cooling or heating ability. If you have a room that becomes stifling hot in summer, an AC unit is the only way to lower the ambient temperature in the room.

While fan systems are generally cheaper, AC systems are also dropping in price. When you consider their greater functionality, you may wish to benefit from a low-cost AC unit.

Many people are not aware that AC units also work as dehumidifiers. This means that your skin's cooling system is more effective due to the average low moisture level in the air.

The Verdict

Fan systems are effective at providing air movement ad a degree of relief in a warm house. However, if you are constantly living or working in a warm or humid environment, you will likely need a more powerful system that can control the temperature in the air.

Fan vs. AC - Which Should You Choose?

There is an ongoing debate about Fan vs. AC. Which is best for you? You likely now have the data you need to be able to choose how you will cool your home.

How to Improve Indoor Air Quality In Your Home This Summer: The Top Hints, Tips, and Tricks

Summer is here, and hot weather isn't the only thing that has arrived with it. For many people, hotter temperatures also mean poor indoor air quality.

This can lead to the development of many unpleasant symptoms, such as headaches, fatigue, and sinus congestion, among others.

Keep reading for five things you can do to improve the indoor air quality in your home.

1. Keep Any Carpets and Rugs Clean

If you have any pets, you know how easy it is for their hair to stick to carpets and rugs. But did you know that carpets and rugs can also trap dust and other particles?

This means that if you clean them, they can work as air filters. However, if they are left dirty, their effects can be damaging.

Clean them once a week to be safe!

2. Control Household Humidity

Depending on where your home is, summer might be a humid and sticky time. If that is the case, the humidity levels in your home should be controlled.

Too much humidity in the air encourages the growth of mold and mildew, which can cause respiratory reactions. Those with allergies and asthma will also find high humidity levels particularly uncomfortable.

Consider buying a dehumidifier to maintain consistent and comfortable levels.

3. Change Your AC Filter

Air conditioners work hard to keep a consistently cool temperature in your home. As they filter through different types of common air pollutants, they stop working as well, and can also negatively affect the air quality of your home.

Change your filter regularly, especially if you live in a city or are prone to allergies.

Comfort Now Air Conditioning and Heating is happy to help you service any air-conditioner, and can even repair or install a new one if necessary.

4. Use Natural Scents

Synthetic fragrances might evoke feelings of cleanliness, but consider using naturally-scented or fragrance-free products instead.

Products such as laundry detergents, cleaning sprays, and air fresheners emit a variety of chemicals into the air. The effects that many of these chemicals have on human health are still not certain.

Using natural or fragrance-free products will eliminate any potential risk.

5. Don't Smoke Indoors

Cigarette smoke contains thousands of different chemicals and is, therefore, a huge factor in indoor air quality.

Not only are these chemicals damaging to the smoker, but they also affect others in the room. Those with secondhand smoke exposure have been found more likely to suffer from respiratory problems and infections.

Many Americans have quit smoking in recent years, but if you haven't, there are a variety of different guides that can help you.

If you still need to smoke, do it outside!

Indoor Air Quality Improvement - Let Us Help You

For many people, summer also means lower indoor air quality. However, this does not need to be the case, and there are several things you can do to keep air quality levels high.

Consider investing in a new HVAC unit, or at the very least repairing or maintaining the one you have.

HVAC troubleshooting

HVAC Troubleshooting Guide: 5 Signs You Need AC Repair This Summer

Would you believe that refrigeration technology, an early attempt at air conditioning, dates all the way back to 1748? Of course, AC as we know and love it today didn't really become practical until the early 20th century. It took many more decades before window units and central systems were affordable enough to be within the economic reach of most Americans.

If you're one of the 90% of the country's households that depend on AC to stay cool and comfortable in the summer months, it's important to familiarize yourself with basic HVAC troubleshooting tips. Read on to learn five signs you need air conditioner repair.

1. It's Not Cool

One clear-cut sign that your HVAC system should be looked at by a professional? It's not cooling as it once did. Even more obvious, it's actually blowing hot air.

One sure sign that your AC needs repair is if it’s blowing hot air. This could be because of a broken compressor or it could signal a refrigerant leak. Another possibility is a broken or disconnected return duct which is drawing in warm air from the outside.

2. Your System Is Noisy

Just like hearing strange noises when you drive your car, loud or unusual noises emanating from the AC can be a sign of big trouble. Unlike with your vehicle, however, you can't just turn up the radio to drown out the noise of your cooling system.

Some of the sounds to keep an ear out for include:

  • Rattling
  • Grinding
  • Banging
  • Screeching
  • Clanking

These could indicate parts that are loose or not aligned properly, broken bearings, or a need for lubrication. Act quickly, as these problems can lead to significant damage. Your entire system may need to be replaced.

3. Elevated Energy Bills

If you open your electrical bill and find a sudden spike in the amount you owe, your air conditioner may be to blame. When there are issues that cause the AC to work harder, it uses more electricity.

Check for a dirty or clogged filter, duct leaks, or a motor that's struggling. If necessary, call your HVAC tech to help troubleshoot the problem.

4. Visible Signs of Moisture

Whether it's a frozen AC coil, condensation on the unit or any other type of water where it shouldn't be, moisture is a scary sign. Don't delay getting professional help in this situation.

Not only can leaks lead to costly repairs, but they can also cause mold or mildew to develop in your home. That's a health hazard as well as a major pain to remedy.

5. Your Unit Is Haunted

OK, your AC isn't actually haunted. But it may seem like it, given that the air conditioning randomly turns off and then back on again. Or maybe you experience significant temperature changes in different areas in the home -- a cool spot here, a warm area there.

Even if the AC sometimes acts unpredictably, as though there's a ghost afoot, there's a rational explanation. Get the pros in to take a look, ASAP.

HVAC Troubleshooting Is Important

Avoid extensive, expensive repairs that will turn your home upside down -- and wreak havoc with your budget. If you don't feel confident diagnosing your own AC issues, give us a call. We'll be happy to do the HVAC troubleshooting for you, then make any necessary repairs!
