When it’s a hot summer afternoon in Phoenix, nothing could be worse than recognizing your air conditioner isn’t operating the way it is supposed to. The last thing you want to do is schedule AC help. But your AC is a pretty complicated system, so it can be difficult to determine what’s creating the trouble solo.

That’s why Dial One Mears Air Conditioning & Heating Inc wrote this guide to help you figure out what might be going on with your cooling system. Below, you’ll find a few common explanations for why your home is feeling a little unpleasant. And though a few of these are straightforward] DIY projects, you could need to turn to an expert for AC repair.

And if you need us, Dial One Mears Air Conditioning & Heating Inc is ready to assist. Here are five reasons why your air conditioner may not be cooling your house in Phoenix.

1. Your Device Settings Are Off

Every home adjusts their thermostat a bit differently to suit their specific requirements. Yet, many families make the mistake of setting their system to “On” instead of “Auto.” Under this setting, the fan in your AC will continue to push out air even after you’ve reached your desired temperature.

This can feel like your system is pushing out untreated air, when in reality it’s just employing the fan on a more regular basis than needed. Trying changing this setting and see if things change.

2. Your HVAC Needs to Be Cleaned

There are two main areas to investigate for dirt or dust accrual when your air conditioner doesn’t seem to be performing well.

First, take a look at your AC system’s filter. If you don’t swap out your filter routinely, accumulated dirt can make it more labor intensive for air to flow through and lower the temperature your house. If your filter is obviously dirty or dusty, it’s likely time to replace it. (And as a rule, you should switch it about once every three months at a minimum.)

If your filter is looking clean, move to your outdoor unit. Find out if there’s a reasonable amount of clearing around your air conditioner and clear any plants or litter close by. This piece of your cooling system lets off the heat from your space. If the coils outside are congested, you won’t be feeling comfortable inside.

We suggest setting professional air conditioner maintenance every year to keep your unit running properly and to keep your warranty valid.

3. Your Unit is Losing Refrigerant

Refrigerant is the chemical that cools the air in your house. It runs between your inside and external system elements to absorb and release heat, to help your home stay comfortable. If there is a leak along the way, you won’t be feeling cool again until you book professional air conditioning repair.

Signs of a refrigerant leak include a decrease in cooled air, more expensive electric charges, frozen evaporator coils and odd hissing noises coming from your AC.

If you suspect refrigerant could be leaking, call Dial One Mears Air Conditioning & Heating Inc for air conditioner repair as soon as possible. Refrigerant can also be harmful to your family’s health.

4. One or More Elements Should Be Replaced

Your system contains a couple important elements. These include the blower, evaporator coils, compressor, fan, condenser coils and expansion valve. If one part is not working as it should, your home comfort will suffer.

Our Dial One Mears Air Conditioning & Heating Inc technicians are well-trained and skilled in all areas of HVAC. They can help you find and mend any issue.

5. Your System Should Be Upgraded

If your equipment is older than 10 years old, it is probably about time to look into new air conditioner installation. As your system gets older, it unfortunately won’t function as well as it has in the past. And it might be making your house less comfortable.

If your AC is newer but still isn’t cooling things off, it could be undersized for your house. Air conditioners are not all the same size. An AC that’s undersized absolutely can’t chill a place the way a properly sized HVAC can.
