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

July 10, 2020

When it’s a searing summer day in Drexel Hill, nothing feels worse than realizing your cooling system isn’t working the way it was built to. The last thing you need to do is schedule air conditioner service. But your HVAC is a quite involved system, so it can be challenging to determine what’s causing the issue solo.

That’s why O'Brien Heating & Air Conditioning crafted this handbook to help you figure out what may be happening with your cooling system. Below, you’ll discover a couple everyday reasons your home is feeling uncomfortable. And while a couple of these are straightforward DIY projects, you could still need to turn to a skilled technician for cooling system repair.

And if need help, O'Brien Heating & Air Conditioning is ready to assist. Here are five reasons why your air conditioner may not be cooling your residence in Drexel Hill.

1. Your Thermostat Settings Are Wrong

Every person uses their thermostat a little differently to work with their distinct needs. However, a lot of households make the misstep of setting their system to “On” instead of “Auto.” With this setting, the fan in your air conditioner will continue to push out air even once you’ve reached your set temperature.

This can appear like your system is pushing out room temperature air, when actually it’s just utilizing the fan on a more regular basis than necessary. Change this setting and work out if things seem better.

2. Your Home Comfort System Needs Some Cleaning

There are two principal areas to inspect for dirt or dust accumulation when your HVAC doesn’t feel like it is operating right.

First off, check out your HVAC filter. If you don’t replace your filter often enough, accumulated dirt can make it hard for air to flow through and lower the temperature your home. If your filter is visibly dirty or dusty, it’s definitely time for a change. (And for best operation, you should switch it about once every three months at the very least.)

If your filter is looking fine, head to your outdoor unit. See if there’s a reasonable amount of clearing around your air conditioner and clean up plants or debris around it. This section of your system discharges the heat from your rooms. If the coils outside are clogged, you won’t be feeling cool indoors.

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

3. Your AC is Releasing Refrigerant

Refrigerant is the chemical that chills the air in your home. It runs between your inside and outdoor system elements to absorb and let off heat, to help your house get comfortable. If there is a leak along that system, you won’t be feeling cool again until you book professional air conditioning repair.

Signals of a refrigerant leak include a decrease in treated air, higher utility charges, frozen evaporator coils and unusual hissing noises arising from your air conditioner.

If you feel refrigerant could be leaking, call O'Brien Heating & Air Conditioning for system 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 system includes a couple essential pieces. These include the blower, evaporator coils, compressor, fan, condenser coils and expansion valve. If one of these is not working, your home comfort crumbles.

Our O'Brien Heating & Air Conditioning experts are well-trained and experienced in HVAC. They can help you locate and repair any problem.

5. Your Air Conditioner Needs to Be Updated

If your equipment is over 10 years old, it could likely be about time to think about new air conditioner installation. As your system ages, it just won’t operate as well as it did in the beginning. And it may be making your house less comfortable.

If your AC is newer but still isn’t cooling things off, it could be the wrong size for your space. Air conditioners are not one-size-fits-all. An AC that’s not powerful enough absolutely can’t cool a house the way a correctly sized AC can.
