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.

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.

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!

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!
