"They came to the house 30 minutes after calling about a broken air-conditioner. This was about 7:00 in the evening. He was able to find the problem and repair it in approximately an hour. I was very relieved that they could fix it, without replacing the compressor. Great service and very professional. I feel the price was fair for an evening service call. Thank you Jason Daniels.

"Amazing technical expertise and physical strength displayed by Mr. Hall who got the water heater to second floor by himself and safely installed my brand new unit. He's also maintained my AC for the last 7 years and recently replaced my thermostat. He is also knowledgeable and able to make electrical repairs and wiring. He is also an honest person who will advise you accordingly."

"I called Ellington Ac to see about a quote for our House in Marathon Key, I had scheduled a free quote . The Morning of the quote Mr. John Page called before hand to let me know he was on his way to the house to present a quote for a new hvac unit and ductwork, For starters he was On time and that is a good sign. He knew all the answers to any questions we had about the Trane Hvac unit. And Ductwork. He even used a thermal Camera::: How impressive:::We decided to go forward with the quote and got the middle of the road unit. The day of the installation Mr Page met the Crew at our House to introduce us to the Installing crew, they were all excellent to have in my house. Very cautious of all our belongings and also worked non stop until the job was complete. They are top notch , attention to detail was excellent ! No corners cut.

Heating and Air Conditioning questions, answered by experts

No, it's not safe to keep using your unit when it's frozen. Not only can running a frozen unit lead to damage, but it can also potentially overheat, making it a fire hazard. Therefore, it's always best to turn off the AC unit as soon as you notice any ice.

Most HVAC companies recommend against setting your AC below 70 as it could freeze up the system and cause more problems. Regardless of how hot it is outside, there is generally a 20 degree difference between the outside and inside temperatures, so even if it’s 100 degrees outside, your AC will likely not be able to cool your home to 70 degrees.

The difference between a home surge protector and an HVAC surge protector is that an HVAC surge protector is designed to protect the components inside your HVAC unit while a home surge protector is installed near appliances and meant to protect your entire home. There are three tiers of whole-house surge protectors, and they are more expensive to install than HVAC surge protectors.

For washable or electrostatic air conditioner filters, you can soak and rinse them with water. If you rinse the filter with water, make sure to use a faucet, shower head, or garden hose with a gentle water pressure setting, as strong water pressure could damage the filter.

But for disposable filters, water could ruin the filter, even allowing mold to grow in the filter. Instead, these filters should be replaced.

You should get anywhere from three to five quotes for HVAC replacement to get an idea of the average cost of a new unit. Although this quote-collecting process can be time consuming, it allows you to compare what work is required, what type of unit you should install, and how much you should expect to pay for the service.
