6 Common Causes of an AC Become Inefficient

air-conditioner-money-saver

A great air conditioning system does more than keep your house cool. It keeps your house cool without wasting energy. In other words, it runs efficiently

But the same way that an AC can start to decline and provide less cool air, it can also start to become inefficient and waste energy. The two don’t even have to go together: you might still enjoy ideal comfort from your air conditioner yet see a tremendous rise in utility bills. If you have a problem with an inefficient air conditioner, you may need AC repair in Macclenny, FL—or possibly a new air conditioner!

We’ll look at six ways an AC can become inefficient. 

#1. Clogged air filter

We put this one first because it’s common but also easily resolved. If you leave the air filter in the HVAC system in place for more than three months, it will clog up and force the blower fan to work harder to circulate air. Change the filter for a clean one, and keep up with changes every 1 to 3 months to prevent this in the future.

#2. Poor initial installation

We stress with customers that they must have licensed professionals install their air conditioning systems. A poor installation may disguise itself at first and appear to run fine. But errors in duct connections, the drainage system, and proper system sizing can lead to an inefficient AC in only a few years. 

#3. Lack of maintenance

This is a problem that should be easy to avoid: just remember to have maintenance for your AC done each spring. We know, easier said than done! Signing up for our maintenance program makes it simpler to have this vital job done each year, and it makes a big difference. An AC will lose, on average 5% of its efficiency each year it misses maintenance. With maintenance, it will only lose around 5% of its efficiency over most of its service life. 

#4. Leaking air ducts

The destroyer of your air conditioner’s efficiency may lurk in the ventilation system rather than the AC itself. As ducts age, they can sag and begin to weaken, leading to leaks developing. Air leaks in the ducts can account for losing up to 30% of the air moving through them, and that will cut massively into an air conditioner’s efficiency. 

#5. Refrigerant loss (and other repair problems)

This is a catch-all category because numerous malfunctions in an air conditioner can cause efficiency drops. Leaking refrigerant, dirty motors, dirty condenser or evaporator coils, a hard-starting compressor, even a faulty thermostat. Always move fast to have repairs done, because even if the AC is still running, it will cost more to operate.

#6. Age

If your air conditioner is more than 15 years old, age will catch up with it and cause an efficiency decline. Maintenance and repairs won’t do much good at this point. When you’ve got an old AC that costs too much to run, time to have our pros install a new one.
