When it’s a searing summer morning in Rapid City, nothing feels worse than realizing your AC isn’t working the way it should. The last thing you want to do is call for cooling system service. But your AC is a fairly complicated system, so it can be hard to figure out what’s creating the issue solo.

That’s why Street Heating and Cooling wrote this guide to help you figure out what might be happening with your home comfort system. Here, you’ll find a couple common situtations that explain why your home is feeling uncomfortable. And while a few of these are simple] DIY projects, you may have to turn to a professional for air conditioner repair.

And if you do, Street Heating and Cooling is ready to assist. Here are five reasons why your air conditioner may not be cooling your residence in Rapid City.

1. Your Thermostat Settings May Be Incorrect

Every family sets their thermostat a touch differently to work with their specific needs. Yet, many people make the error of setting their system to “On” as opposed to “Auto.” Under this setting, the fan in your air conditioner will continue to produce an air current even once you’ve achieved your preferred temperature.

This can seem like your vents are distributing untreated air, when in reality it’s just utilizing the fan on a more regular basis than necessary. Change this setting and see if things change.

2. Your HVAC Needs to Be Cleaned

There are two main spaces to look for dirt or dust buildup when your cooling system doesn’t feel like it is performing well.

Firstly, check out your system’s filter. If you don’t swap out your filter on a regular basis, built-up dust can make it hard for air to flow through and cool your home. If your filter is noticeably dirty or dusty, it’s definitely time to replace it. (And in general, you have to change it about once every three months at the very least.)

If your filter seems fine, move to your outside unit. Double check there’s a reasonable amount of space around your air conditioner and clear away plants or debris stuck there. This piece of your AC releases the heat from your house. If the coils outside are clogged, you won’t be feeling comfortable indoors.

We advise 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 material that chills the air in your space. It runs between your internal and outdoor units to absorb and let off heat, to help your home remain comfortable. If there is an opening along that path, you won’t be feeling comfortable again until you schedule professional air conditioning repair.

Signals of a refrigerant leak include a decrease in chilled air, more expensive electric bills, frozen evaporator coils and odd hissing noises originating from your air conditioner.

If you think refrigerant might be leaking, call Street Heating and Cooling for system repair as soon as possible. Refrigerant can also be damaging to your family’s health.

4. One or More Pieces Have to Be Replaced

Your air conditioner is made up of a a handful of crucial parts. These include the blower, evaporator coils, compressor, fan, condenser coils and expansion valve. If any one of these is failing, your home comfort suffers.

Our Street Heating and Cooling experts are trained and experienced in HVAC. They can help you locate and fix any issue.

5. Your AC Has to Be Upgraded

If your equipment is over 10 years old, it may be time to look into new air conditioner installation. As your system gets up there in years, it just won’t run as well as it once did. And it could be making your home uncomfortable.

If your AC is on the younger side but still isn’t properly cooling your home, it may be too small for your house. Air conditioners are not all the same size. An air conditioner that’s not big enough just can’t cool a house the way a correctly sized system can.
