3 Common Evaporator Coil Issues and What Can Be Done About Them

- Published by
Evaporator Coil

Air conditioners don’t just blow cool air into your house. They actually remove the heat from inside your home. How they do that is a little complicated, but the evaporator coil in your air conditioner plays a big part in the process, which means that evaporator coil issues can have a significant effect on how well your A/C functions. In Florida, that’s a significant effect on your home!

Here’s how the coil works: compressed refrigerant circulates through your air conditioner, between the indoor and outdoor units. The evaporator coils, in the indoor unit, are chilled so that when the unit pulls in the warm, humid air, the heat soaks into the coil and the air cools. The cooled air blows back into your house, and the warmed refrigerant is sent outside. There, it expels the heat it’s picked up and comes back in for the next round.

Three common evaporator coil issues can interfere with that heat transfer:

  1. Dirty coils – When there’s dirt and dust on your evaporator coils, it can act like a layer of insulation between the coil and the indoor air. This makes it harder for the coil to soak up heat. You want insulation for your walls, attics and ducts, but not your A/C coils!
  2. Condensation – You know the droplets on your glass when you take a cold drink outside on a hot summer day? In an A/C, the coil is so often cold, condensation has many chances to develop and collect there. If it’s not drained out, it could be a place for bacteria and mold to grow, which is not only unhealthy, but it could also prevent heat transfer.
  3. Frozen coils – Coils can freeze if there’s not enough refrigerant in the system, or if not enough of your warm air is flowing through.

So what can you do? After unplugging the unit, you can clean the coils in some models with a damp cloth and check the drain.

But to be on the safe side, if you experience these evaporator coil issues, call us at Scott’s Heating & Air Conditioning. We can tackle all of your home comfort needs!

AC Service Testimonials

I had called many different companies. They all either wanted to charge commercial fees due to ladder size or they couldn't get out for days. I called Scott's on a Tuesday. They had me scheduled for Wednesday. When they got here they quickly realized a 24ft ladder wouldn't be long enough to reach our roof (2 story condo) they drove back to their warehouse to get a 32ft ladder. They then got on the roof and diagnosed the problem and got it fixed. It was decently priced and quick service. We will definitely be using them again if need be

Just replaced my AC with Scott’s and it was a very pleasant and professional experience. They came out to service our old unit and showed me exactly what was wrong, didn’t talk down to us and was very upfront about all of our options. During pricing gave us several detailed options and even priced a different manufacturer that I had requested. Didn’t pressure us into one or the other it was very much our decision. Booked everything quickly and it was easy to get a hold of them. When we priced with different providers they were not our cheapest option, however the difference in the quality of service was completely worth it.

Santiago and Michelle were great. Our AC went out on Sunday night. I called at 8AM on Monday morning and spoke with Michelle, who quickly found us an appointment. By 9AM Santiago was at our home, and by 930 the AC was fixed. They were very helpful, friendly, professional, and knowledgeable. We have used Scott’s for several years now and we are continually impressed by their friendly and knowledgeable employees! We will continue to use them because of their employees!

Extremely satisfied with my new HVAC system from Scott's. I received prompt attention from Craig, our salesperson, with explanations and quotes for units to fit our needs. The installation team, Josh and Will, were professional, courteous, extremely proficient at their job and left not one spec of debris behind. Jessica, office staff, was helpful with follow-up and checked to ensure all my questions were answered and system was working well. I chose this company for their A+ BBB rating and have been very satisfied.

Very professional company from the phone calls to the service rep!I am glad I made that first phone call to Scott's to get my A/C serviced. The tech was incredibly knowledgeable and explained what he was doing and why. I told him he's the only tech that spent so much time servicing my system! He really cares about what he does! Great job! I'll keep signing up for the annual service on the A/C!

Oh my god what an amazing company! I literally called one hour ago and said that my thermostat wasn’t working and there was a knock on my door within the hour! They told us what to do to fix it therefore saving us a $600 bill. They came right away, none of that we can see you in 48 hour junk. Amazing.

They were able to provide me with same day service, friendly and very responsive. Also, I got 2 other quotes and the pricing was the most competitive.
So thankful and impressed! My dad returned home after having open heart surgery to a completely dead HVAC system in the middle of summer. Definitely not ideal. The repair was going to be pricey so he opted for a new unit. A crew came out on a Saturday and did a very clean and efficient install. Highly recommend this company!!!

Our AC decided to quit during one of the hottest heatwaves in years. We called Scott's and someone was at the house to give us a quote in 30 min. From the moment they answered our first phone call through the install everyone was amazing, professional and provided a quality product and excellent service. Craig, Jose, Dexter were awesome! One of the new guys brought us a portable unit at 9:30 PM on a Friday so we could sleep. We missed his name, but shout out to him as well (he likes to give high fives). Thanks Scott and team for everything. We highly recommend!!!

For the past week I've worked with Craig on getting estimates for a new A/C unit, and he has been great at answering my questions and addressing any concerns. Very responsive and knowledgeable, straight shooter and direct! I didn't have to deal with any up-selling like working with a used car salesman (I experienced that with other bigger local A/C companies providing quotes). For these qualities alone I would recommend Scott's A/C, even though I will disclose that we ultimately went with another quote from a family referral of an A/C company. Had that family referral not been apart of our consideration, we would definitely choose and recommend Scott's for new A/C installs and service!

We can't thank Scott's enough. We came home to a air conditioner barely limping along. I called Scott's first thing in the morning and they had a technician out that day. Unfortunately our system could not be saved. The salesman Craig came out that day as well and quoted a new system. Since it was a Friday we could not get the system installed until Tuesday. Scott's provided us with a portable system which definitely helped during the grueling heat wave in Central Florida. Tuesday came, the installers showed up on time and did an awesome installation job. Cleaned everything up and went on their way. Everyone was pleasant, professional and great to work with! Thank You Scott's Heating & Cooling!
