When it’s a searing summer morning in Phoenix, nothing is worse than recognizing your air conditioner isn’t performing the way it should. The last thing you want to do is schedule AC help. But your air conditioner is a quite complicated system, so it can be almost impossible to figure out what’s creating the problem solo.

That’s why Dial One Mears Air Conditioning & Heating Inc made this informational guide to help you understand what could be happening with your home comfort system. From here, you’ll see a couple typical explanations for why your home is feeling too warm. And though a couple of these are straightforward] DIY projects, you may still need to turn to a pro for HVAC repair.

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

1. Your Thermostat Settings May Be Incorrect

Everyone adjusts their thermostat a touch differently to match their specific preferences. Even so, many homeowners make the misstep of setting their system to “On” rather than “Auto.” With this setting, the fan in your air conditioner will continue to blow even once you’ve achieved your preferred temperature.

This can look like your vents are distributing warm air, when actually it’s just utilizing the fan more frequently than required. Try switching this setting and work out if things cool off.

2. Your Home Comfort System Needs a Good Cleaning

There are two main areas to investigate for dirt or dust accumulation when your home comfort system doesn’t feel like it is working as it should.

Before anything else, take a look at your AC system’s filter. If you don’t switch your filter on a regular basis, built-up dust can make it more labor intensive for air to flow through and cool your home. If your filter is obviously dirty or dusty, it’s definitely time to replace it. (And as a rule, you have to replace it about once every three months at a minimum.)

If your filter is looking clean, head to your outside unit. Double check there’s adequate space around the unit and clear away plants or debris stuck there. This piece of your cooling system discharges the heat from your house. If the coils outside are congested, you won’t be feeling comfortable in your home.

We advise setting professional air conditioner maintenance each year to keep your unit running like it should and to keep your warranty valid.

3. Your AC is Losing Refrigerant

Refrigerant is the substance that chills the air in your space. It runs between your internal and outside units to soak up and let off heat, to help your space stay the right temperature. If there is a crack along the way, you won’t be feeling cool again until you set professional air conditioning repair.

Signs of a refrigerant leak include a lack of cooled air, higher monthly bills, frozen evaporator coils and strange hissing noises coming from your system.

If you are worried refrigerant could be leaking, call Dial One Mears Air Conditioning & Heating Inc for HVAC repair as soon as possible. Refrigerant can also be hazardous to your family’s health.

4. One or More Elements Need to Be Replaced

5. Your Air Conditioner Should Be Replaced

If your AC is older than 10 years old, it is probably a good time to research new air conditioner installation. As your system ages, it unfortunately won’t work as well as it did in the beginning. And it could be making your house uncomfortable.

If your HVAC unit is on the younger side but still isn’t cutting it, it could be too small for your house. HVAC systems are not all the same. An air conditioner that’s too small simply can’t cool a place the way a properly sized HVAC can.
