Old Appliance
An old AC unit will not work as efficiently as a new one. Parts will start to fail and need replacement while the refrigerant requires recharging. An old appliance uses more energy to run, takes longer to cool the space, and might not evenly cool the room.
Replace the old unit with a new and more energy-efficient model. Doing this saves money in the long run. Check Mister Quik Home Services tips for AC replacement. Doing so ensures you get your home’s right size, model, and features.
Dirty Air Filters
Over time, filters become clogged with dirt, dust, and other airborne particles. It prevents proper airflow and strains the AC unit. As a result, it has to work harder to cool the air, using more energy and increasing your utility bills. A dirty filter also causes the evaporator coils to freeze.
Clean or replace the filter every one to three months, depending on the manufacturer’s recommendations. If you have pets or live in a dusty area, do it more often.
Poor Maintenance
Not cleaning and servicing the unit will shorten its lifespan. It will also lead to higher energy bills and repair costs. A poorly maintained unit breaks down often, accumulates dust, and doesn’t work as efficiently.
Hire a professional to service the unit at least once a year. An expert will clean the coils, check the Freon levels, and inspect the entire system. The effort prevents AC issues and keeps it working properly.
Thermostat Issues
The thermostat controls the temperature in your home. If it’s not working properly, the unit will either overwork or not work. A thermostat that’s not properly calibrated will cause the AC to run too often, using more energy in the process. If it’s not working, the unit won’t turn on.
Fixing a thermostat is best left to a professional. The expert will properly calibrate it and make any necessary repairs. However, change the batteries at least once a year.
Leaking Refrigerant
If the AC leaks refrigerant, it will not cool the air properly. The evaporator coils will also freeze, causing the unit to shut down. A Freon leak can also be damaging to the environment.
A professional will fix the leak and recharge the refrigerant. They will also inspect the entire system for any other issues.
Drip Pan Overflow
The drip pan collects water that drips from the evaporator coils. If it’s full, the water will overflow, causing water damage. The unit will also shut down to prevent any further damage. First, check the pan to see if it needs emptying. If there’s a leak, the cause might be a blocked drain line.
Let an expert inspect the system to determine the cause of the overflow and reset the floater switch. Also, have them clean the drain line and pan to prevent future issues.
Improper Installation
An improperly installed AC unit will not work correctly. It might also void the warranty. Incorrect installation can cause various issues, such as water leaks, strange noises, and decreased efficiency. To avoid this, hire a professional to install the unit according to the manufacturer’s instructions. It also pays to consult the experts before purchasing the unit. They can help you choose the right size and model for your home.
Frozen Evaporator Coils
The evaporator coils turn the warm air cold. If they freeze, the unit cannot properly cool the air. It usually happens because the air filter is dirty or the coils are not getting enough air.
First, try cleaning or replacing the air filter. If that doesn’t work, the coils need defrosting. A professional can do this quickly and efficiently.
Compressor Issues
The compressor is the heart of the AC unit. If it’s not working, the entire system will shut down. This issue is usually caused by a power surge, incorrect installation, or poor maintenance. A professional will assess the situation and make any necessary repairs.
Be On The Look Out
These are some of the most common AC issues. Call a professional when you suspect there’s a problem. They will quickly diagnose and fix the issue, preventing further damage to the unit. Signs to look out for are strange noises, unusual smells, and increased energy bills.
