The Most Common A/C Problems You May See This Cooling Season

Schedule Now

The long, hot Cincinnati summers can take a toll on your cooling system. If you haven’t already scheduled your A/C preventive maintenance, it’s not too late. An annual tune-up will go a long way toward lowering your cooling costs, extending the life of your system and preventing these common A/C problems.

Electric control failure

Over time, wires and terminals may become corroded and electrical connections may loosen. During your maintenance visit, your qualified HVAC technician will check the wiring and tighten connections, as well as test the controls of the system to ensure it cycles properly.

Dust buildup

Dust in your system can cause the premature failure of the fan, motor and condenser. Your technician will remove the dust buildup to ensure your system operates efficiently and extend the life of these essential components. You can help prevent dust from building up inside your system by performing these tasks throughout the summer:

  • Vacuum the area around your indoor unit regularly to remove dust.
  • Hose down your outdoor unit monthly to remove dirt and debris from the fins.
  • Check your air filter each month and replace it when it’s dirty.

Drainage problems

The condensate pan under your evaporator coil catches the condensation that drips from the coil during periods of high humidity. Clogs can cause the pan to overflow, resulting in the shutdown of your system. Preventive maintenance includes flushing the drain to prevent this common problem. If your drain becomes clogged, you can remove the obstruction with a plumber’s snake or a wet/dry vacuum.

Low refrigerant

If your system has ice buildup or it’s not cooling effectively, you may have a refrigerant leak. Your technician will measure the refrigerant level and test for leaks if it’s low. If a leak is detected, it will be sealed and your system will be topped off with the correct amount of refrigerant, according to the manufacturer’s specifications.

"Ernie & Mike did a superb job on my new furnace and A/C installation. Despite having more than a day’s work to do, they came in and stayed until the job was done. They were organized, efficient, and protected the rest of the house well. Got both furnace and A/C installed the same day. Ernie was courteous, informative, and clearly knew his job better than anyone I’ve encountered before. The units look so good guests now get The Tour of our new system. Apollo is clearly not a fly-by-night company. I would recommend them to anyone in need of a new furnace and/or A/C."

"I called Apollo because of a water leak I thought I had in our upstairs shower going into the kitchen. Robbie came and assured me everything was fine & looked at all the other plumbing. He ended up changing a few pipes for our washer & clearing a drain. He was very nice & knowledgeable with all my questions. I ended up signing up for the care plan & was very happy with my service."
- Cassandra B.
"The team at Apollo exceeded my expectations. As a business owner, my attention to the details and commitment to providing excellent service is high. From the sales rep. to the installation team, everyone’s performance was outstanding. For example, the installation team went to great lengths to protect our floors, placing floor runners and across the wood floors and up the stairs. They even were spot washing walls upon their departure. I highly recommend this company."

"We scheduled an estimate AND a tune-up. We knew something was wrong with our furnace, but hoped we could make it through the rest of the season. Upon telling Bill what our furnace was doing, he warned us immediately what the possible outcome was going to be; a cracked heat exchanger. He watched the flames roll backward, tested carbon monoxide levels, which were so high they meter’s last reading was 5,600 before saying “high”. He immediately shut it down, tagged it, and explained that with levels that high and children in our home he wanted off right away. He continued his inspection and showed us via a camera that not only was it cracked in multiple places, but had holes all over it. He gave us a few options for repairing it; his knowledge as well as genuine concern was beneficial and refreshing. Luckily we also scheduled an estimator, Micah, to come too and we were able to get costs between repairing and replacing (with several options). We decided to replace with a much higher efficiency furnace and one sized properly to our home. Hands down, not only did they both provide us great service and knowledge, but without sounding dramatic, they may have saved our lives. This was our first time calling Apollo, but it won’t be our last."

"Apollo is an excellent company. I always receive great service. Alex A. was professional and friendly. He kept me informed during the process of checking my furnace and heat pump to make sure they were working properly. The company makes sure you are notified who is coming and when they are on the way. All my interactions with the company have been wonderful."
