Five Reasons Why Your Air Conditioner Isn't Cooling Your Home

July 10, 2020

When it’s a searing summer afternoon in Payson, nothing feels worse than realizing your home comfort system isn’t operating the way it was built to. The last thing you want to do is schedule AC help. But your air conditioner is an incredibly intricate system, so it can be hard to deduce what’s causing the issue solo.

That’s why North Mechanical Heating and Cooling made this handbook to help you find out what might be going on with your air conditioner. Here, you’ll uncover a few prevailing reasons your home is feeling a little too warm. And while some of these are simple DIY activities, you may want to turn to a skilled technician for air conditioner repair.

And if that’s the case, North Mechanical Heating and Cooling is ready to assist. Here are five reasons why your air conditioner may not be cooling your house in Payson.

1. Your Thermostat Settings Could Be Wrong

Every home uses their thermostat a little differently to match their distinct needs. However, many families make the error of setting their system to “On” rather than “Auto.” Under this setting, the fan in your AC will continue to push out air even once you’ve gotten to your preferred temperature.

This can look like your vents are releasing room temperature air, when in fact it’s just using the fan more often than needed. Trying changing this setting and see if things cool off.

2. Your Cooling System Needs Some Cleaning

There are two primary spaces to examine for dirt or dust collection when your AC doesn’t appear to be operating as it should.

Firstly, examine your AC system’s filter. If you don’t switch out your filter on a regular basis, built-up dust can make it more labor intensive for air to flow through and cool down your rooms. If your filter is clearly dirty or dusty, it’s likely time for a change. (And for best operation, you should replace it about once every three months or more frequently.)

If your filter appears clean, go to your external unit. Double check there’s a reasonable amount of space around the unit and clear any plants or litter around it. This element of your home comfort system lets off the heat from inside your rooms. If the coils outside are clogged, you won’t be feeling comfortable in your home.

We suggest setting professional air conditioner maintenance each year to keep your equipment working smoothly and to keep your warranty valid.

3. Your System is Releasing Refrigerant

Refrigerant is the substance that cools the air in your space. It runs between your indoor and outdoor units to absorb and release heat, to help your rooms keep the right temperature. If there is a leak along the way, you won’t be feeling cool again until you book professional air conditioning repair.

Indicators of a refrigerant leak include a decline in treated air, climbing utility charges, frozen evaporator coils and unusual hissing noises coming from your AC.

If you think refrigerant may be leaking, call North Mechanical Heating and Cooling for AC repair as soon as possible. Refrigerant can also be hazardous to your family’s health.

4. One or More Elements Need to Be Replaced

Your cooling system includes a couple crucial parts. These include the blower, evaporator coils, compressor, fan, condenser coils and expansion valve. If one part is broken, your home comfort will suffer.

Our North Mechanical Heating and Cooling technicians are well-trained and experienced in HVAC. They can help you find and mend any issue.

5. Your Air Conditioner Should Be Replaced

If your equipment is over 10 years old, it is probably time to look into new air conditioner installation. As your system ages, it just won’t operate as well as it has in the past. And it might be making your place uncomfortable.

If your HVAC unit is newer but still isn’t cooling things off, it may be too small for your living space. Air conditioners are not all the same size. An air conditioner that’s too small absolutely can’t cool a house the way a properly sized AC can.
