When it’s a searing summer afternoon in Phoenix, nothing is worse than registering your home comfort system isn’t working the way it should. The last thing you need to do is schedule cooling system service. But your AC is a fairly intricate system, so it can be almost impossible to find out what’s causing the issue solo.

That’s why Integrity AC & Heating LLC made this handbook to help you see what might be going on with your AC. Here, you’ll see a couple common explanations for why your home is feeling uncomfortable. And though a couple of these are straightforward] DIY projects, you might need to turn to a skilled technician for HVAC repair.

And if that’s the case, Integrity AC & Heating LLC is ready to assist. Here are five reasons why your air conditioner may not be cooling your house in Phoenix.

1. Your System Settings Could Be Wrong

Every family adjusts their thermostat a touch differently to suit their specific requirements. Yet, many families make the misstep of setting their system to “On” as opposed to “Auto.” Because of this setting, the fan in your AC will continue to push out air even after you’ve attained your desired temperature.

This can look like your AC is pushing out warm air, when really it’s just employing the fan on a more regular basis than necessary. Change this setting and see if things change.

2. Your Air Conditioner Needs a Good Cleaning

There are two central places to look for dirt or dust accumulation when your air conditioner doesn’t appear to be performing as it should.

Before anything else, check out your system’s filter. If you don’t change your filter routinely, buildup can make it more labor intensive for air to move through and cool down your space. If your filter is visibly dirty or dusty, it’s probably time to replace it. (And as a rule, you have to switch it about once every three months at a minimum.)

If your filter appears clean, go to your outdoor unit. Make sure there’s enough space around it and clear any plants or litter close by. This piece of your system lets off the heat from inside your house. If the coils outside are clogged, you won’t be feeling comfortable in your home.

We suggest setting professional air conditioner maintenance yearly to keep your system operating properly and to keep your warranty valid.

3. Your Unit is Leaking Refrigerant

Refrigerant is the chemical that chills the air in your space. It cycles between your indoor and outside units to absorb and discharge heat, to help your house keep the right temperature. If there is a leak along that path, you won’t be comfortable again until you set professional air conditioning repair.

Indications of a refrigerant leak include a decrease in conditioned air, more expensive monthly charges, frozen evaporator coils and unusual hissing noises originating from your air conditioner.

If you think refrigerant may be leaking, call Integrity AC & Heating LLC for AC repair as soon as possible. Refrigerant can also be harmful to your family’s health.

4. One or More Pieces Have to Be Replaced

Your air conditioner contains a couple essential pieces. These include the blower, evaporator coils, compressor, fan, condenser coils and expansion valve. If any one of these is not working as it should, your home comfort is hurt.

Our Integrity AC & Heating LLC experts are well-trained and knowledged in HVAC. They can help you locate and repair any issue.

5. Your Air Conditioner Needs to Be Replaced

If your system is more than 10 years old, it could likely be a good time to think about new air conditioner installation. As your system ages, it just won’t run as well as it once did. And it may be making your house too warm.

If your system is newer but still isn’t keeping you cool, it may be undersized for your home. HVAC systems are not all the same size. A cooling system that’s undersized simply can’t chill a home the way a correctly sized air conditioner can.
