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

July 10, 2020

When it’s a searing summer day in Cambridge, nothing feels worse than realizing your home comfort system isn’t operating the way it is meant to. The last thing you should have to do is call for AC repair. But your air conditioner is a fairly complex system, so it can be difficult to find out what’s driving the trouble all alone.

That’s why Pliescott HVAC Services LLC made this guide to help you understand what could be going on with your air conditioner. From here, you’ll see a few usual explanations for why your house is feeling too warm. And even though a few of these are fairly painless DIY activities, you might want to bring in a pro for cooling system repair.

And if that’s the case, Pliescott HVAC Services LLC is here for you. Here are five reasons why your air conditioner may not be cooling your house in Cambridge.

1. Your System Settings May Be Off

Every home adjusts their thermostat a little differently to match their personal needs. Yet, a lot of households make the error of setting their device to “On” as opposed to “Auto.” With this setting, the fan in your AC will continue to produce an air current even when you’ve reached your desired temperature.

This can look like your air conditioner releasing warm air, when in fact it’s only using the fan more frequently than necessary. Swap this setting and find out if things change.

2. Your AC Needs a Good Cleaning

There are two principal places to investigate for dirt or dust accrual when your cooling system doesn’t appear to be working correctly.

First, check out your AC system’s filter. If you don’t switch your filter regularly, built-up dust can make it more challenging for air to pass through and cool down your space. If your filter is clearly dirty or dusty, it’s probably time to replace it. (And for best operation, you need to replace it about once every three months at the very least.)

If your filter seems clean, head to your outside unit. Double check there’s adequate space around the unit and clear away plants or dirt around it. This element of your cooling system discharges the heat from within your rooms. If the coils outside are blocked, you won’t be feeling cool in your home.

We suggest setting professional air conditioner maintenance every year to keep your system running smoothly and to keep your warranty valid.

3. Your System is Losing Refrigerant

Refrigerant is the stuff that conditions the air in your home. It moves between your internal and external system pieces to absorb and let off heat, to help your rooms remain comfortable. If there is an opening along the way, you won’t be comfortable again until you set professional air conditioning repair.

Signals of a refrigerant leak include a decline in cooled air, higher utility bills, frozen evaporator coils and odd hissing noises originating from your HVAC.

If you are worried refrigerant could be leaking, call Pliescott HVAC Services LLC for HVAC repair as soon as possible. Refrigerant can also be hazardous to your family’s health.

4. One or More Pieces Have to Be Replaced

Your air conditioner contains a couple important pieces. These include the blower, evaporator coils, compressor, fan, condenser coils and expansion valve. If any one of these is broken, your home comfort will suffer.

Our Pliescott HVAC Services LLC pros are trained and skilled in all areas of HVAC. They can help you find and fix any trouble.

5. Your Air Conditioner Needs to Be Upgraded

If your AC is more than 10 years old, it is probably a good time to look into new air conditioner installation. As your system ages, it sadly won’t operate as well as it has in the past. And it might be making your home less comfortable.

If your air conditioner is more current but still isn’t keeping you cool, it could be too small for your home. HVAC systems are not one-size-fits-all. A cooling system that’s not powerful enough simply can’t chill a place the way a correctly sized system can.
