When it’s a searing summer morning in Derby, nothing is worse than recognizing your AC isn’t working the way it was built to. The last thing you should have to do is call for AC service. But your HVAC is a quite complicated system, so it can be difficult to find out what’s causing the issue solo.

That’s why Giordanos Heating and Air Conditioning wrote this guide to help you understand what could be going on with your home comfort system. Here, you’ll find a couple common explanations for why your space is feeling too warm. And even though a few of these are easy] DIY projects, you could have to turn to a professional for cooling system repair.

And if that’s the case, Giordanos Heating and Air Conditioning is prepared to take care of your home. Here are five reasons why your air conditioner may not be cooling your house in Derby.

1. Your Device Settings Are Off

Everyone adjusts their thermostat a little differently to match their individual requirements. Even so, a lot of homeowners make the mistake of setting their thermostat to “On” as opposed to “Auto.” Under this setting, the fan in your AC will continue to blow even once you’ve reached your desired temperature.

This can seem like your AC is distributing warm air, when really it’s simply utilizing the fan on a more regular basis than needed. Change this setting and see if things cool off.

2. Your AC Needs to Be Cleaned

There are two main areas to investigate for dirt or dust accumulation when your air conditioner doesn’t feel like it is operating correctly.

Firstly, examine your HVAC filter. If you don’t change your filter routinely, accumulated dirt can make it hard for air to flow through and lower the temperature 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 the very least.)

If your filter appears clean, go to your outside unit. Make sure there’s a reasonable amount of space around it and clear away plants or litter close by. This section of your cooling system lets off the heat from your home. If the coils outside are congested, you won’t be comfortable indoors.

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

3. Your System is Losing Refrigerant

Refrigerant is the chemical that chills the air in your space. It cycles between your indoor and outside system pieces to absorb and let off heat, to help your space remain the right temperature. If there is a leak along that path, you won’t be comfortable again until you book professional air conditioning repair.

Indications of a refrigerant leak include a decline in chilled air, higher electric bills, frozen evaporator coils and strange hissing noises coming from your system.

If you think refrigerant could be leaking, call Giordanos Heating and Air Conditioning for AC repair as soon as possible. Refrigerant can also be harmful to your family’s health.

4. One or More Parts Need to Be Replaced

Your air conditioner is made up of a few important parts. These include the blower, evaporator coils, compressor, fan, condenser coils and expansion valve. If one of these is not working as it should, your home comfort will suffer.

Our Giordanos Heating and Air Conditioning technicians are well-trained and experienced in HVAC. They can help you find and repair any problem.

5. Your AC Should Be Upgraded

If your equipment is more than 10 years old, it could likely be time to research new air conditioner installation. As your system gets up there in years, it sadly won’t work as well as it did in the beginning. And it could be making your space too warm.

If your HVAC unit is newer but still isn’t cooling things off, it may be the wrong size for your house. AC units are not all the same size. A cooling system that’s not big enough absolutely can’t cool a space the way a correctly sized air conditioner can.
