How to Fix Common Problems With Your Air Conditioner

Home-Tech has been repairing and replacing AC systems in Southwest Florida since 1981. Get back to enjoying your home with this troubleshooting guide to help you address the most common air conditioner problems.

Air Conditioner Won’t Turn On

1. Set your thermostat to cool (if it isn’t already) and lower the temperature a good 5 degrees or more. The fan should be set to Auto not On.

2. Go outside and check the unit to see if it is running and if there is any debris on the coils. If you see debris, first turn off the power source to your AC. You can spray the outside of the unit with a garden hose to try to remove the debris. If that doesn’t remove the debris, please contact us for a more thorough cleaning.

3. Check to see if you have a blown fuse or tripped circuit breaker. If fuse is blown, replace the fuse. If the circuit breaker is tripped, reset it but do not force it if it trips right away again.

4. Make sure you have a clean air filter! If they get clogged with dirt, the AC will not have proper air flow. This causes your AC to struggle to circulate enough cool air to get your home to the desired temperature. It also can cause your evaporator coil to freeze, blocking air. If you have a dirty air filter, replace it with a new one.

5. If you did have a dirty/clogged air filter, you could have a clogged condensate drain line. Use a shop vac to suck out the drain line which is likely near the outside unit, coming out of the wall or sticking out of the ground. Leave it on the line for a bit. You will eventually see sludge, dirt and/or mold in the water inside the shop vac. If it’s too clogged you will need to contact us. We use a special vacuum to suck out the blockage.

6. You could possibly have a refrigerant leak. The only way to really know this is to have a professional take a look. Contact us right away if you are at all unsure if this is the problem with your air conditioner. This could lead to health issues.

7. If your AC has been making weird sounds before it stopped working altogether, your motor may have stopped working. If your motor isn’t working, we will give you a quote for the cost to fix it (if possible) versus the cost to replace the AC unit.

8. Your thermostat may need to be replaced. Because it is the control panel for your air conditioner, if it is not working properly it can stop your AC from turning on. If the thermostat screen is blank, displaying a symbol to replace the batteries, broken or outdated, you will need to address the issue.

Air Conditioner Is Not Cooling

So the AC is running but the air is just not cool. Here are some problems you can try to solve.

1. Check that your thermostat fan is set to Auto not On. When in the On position, the fan will run 24/7 – even if the air coming out is not being cooled.

2. Check your air filter. A dirty air filter will reduce airflow into your AC. This can cause the AC to struggle to circulate enough cool air to get your home to the desired temperature. It also can cause your evaporator coil to freeze, blocking air. If you have a dirty air filter, replace it with a new one.

3. If you did have a dirty/clogged air filter, you could have a clogged condensate drain line. Use a shop vac to suck out the drain line which is likely near the outside unit, coming out of the wall or sticking out of the ground. Leave it on the line for a bit. You will eventually see sludge, dirt and/or mold in the water inside the shop vac. If it’s too clogged you will need to contact us. We use a special vacuum to suck out the blockage.

4. Check the outside unit for dirt and debris. If there is a bunch of debris caught in the grill it causes your air conditioner to struggle to cool your home. Turn off the power source to your AC. Spray the outside with a garden hose on a gentle setting. Remove any debris blocking the grill. It needs breathing room! If this doesn’t do the trick, please contact us for a more thorough cleaning.

5. You could have a refrigerant leak. In this case you really need to contact us!

6. You could have a bad compressor, which circulates refrigerant between the inside and outside units. If the compressor is damaged, the air conditioner cannot cool your air. If this is the case, we can give you a quote for fixing it or replacing the entire outside unit.

Employee Ownership

“The key difference is quite simple. Employees own the business,” says the CEO, Steve Marino. “I think it’s the perfect model for a service business in Southwest Florida. What we offer employees is a piece of their business. When someone is vested, when they own a stake in something, they are more likely to stay. What does this mean to our customers? Our employees really care that every experience you have, every service that is done is TOP NOTCH.”
