I had a 14 year old system using Freon that was not cooling as it once did. I called Cantrell's Heat and Air looking for some guidance. I received prompt service. The technician revived my system and did some further checking of it at my request. The Freon R22 was leaking from the cooling coil. I asked what my options were since it was an R22 system. A new cooling coil or repair of the old coil was not an option and the cost to try and repair this system was not recommended. After exploring the options I elected to go for it all and replace the entire heating and cooling system. Five days later a great crew arrived with my new system and in 3 hours had the new system up and running. This crew was amazing in all respects. Not only did they have the knowledge of what had to be done, but completed the task in a neat and professional manner. You would have never known anyone had taken on this task and there was no mess was left behind. I would highly recommend Cantrell's Heat & Air for heating and a/c repairs to anyone.

Dean Plumbing Heating and Cooling
Jonathan Dean and his crew came to the rescue! I had many other estimates performed by other companies - all the big names here in Knoxville. He beat their pricing and was able to provide 0 down 0% financing. Most importantly, he thoroughly explained my options, and my house went from 90 degrees back to 70 in less than 30 hours from my first call, with an offer of portable cooling units. I got a great unit, at a great price, and one with locally available parts if service is needed or when the 10 year warranty runs out. I have had the unit for a year now. I wanted to be sure there was service after the sale as well. There was a hiccup with the unit, a small leak caused by a manufacturing defect. That was handled, at 0 charge, the afternoon I called about it, on a Sunday. I have been extremely happy with the entire experience. Thank you, Jonathan Dean. You and your crew do fantastic work and provide professional, courteous and prompt service.

R & R Heating & Air Cond
I would reccomend R & R to everybody. Our unit went out on Friday and the supply house had to order the part since our unit was 14 years old, and it would not be in until Mon. or Tues. so Rusty one of the owners brought us a portable air unit that sat in the floor to use until they got our unit fixed. By keeping the rooms closed off during the day our living room stayed at 79 degrees then at night we would open the bedroom and after about 30 mins. it was cool also. I have never seen a company do such a good deed for one of their customers especially the seniors. The two owners are father and son and they are just great people that really care about others. So I am giving them the HIGHEST rating I can give them I wish I could give them a 10 star rating they deserve it. I would reccomend them very, very, highly.

Advanced Heating & Air
Best service ever!! Advanced Heating and Air is first class! They found a crack in my old furnace which was very dangerous during a fall preventative maintenance check. They gave me all my options and did not pressure me on any sales. They just educated me on my options. I ended up buying a Carrier system from them. The guys that installed my new hvac system were fabulous. They showed me everything they were doing, rolled out some plastic, and wore their shoe covers the whole time they were there. I will refer this company to anyone I know here in Knoxville, Tn.

Knoxville Appliance Repair
They have superior quality service that is really hard to find these days from an appliance repair company. They will respond to your appliance needs promptly without delays so you can be assure that your inconvenience will not be a lengthy one. I like how their operators answer each call professionally and courteously. The service guy that they sent us was technically competent and has years of experience. He was also friendly and neat too. Affordable service charge that you will be greatly happy about. I like everything about them!

I went through some really unfortunate circumstances this year. I still owed a balance to Cantrell’s for some work they did and instead of making my life harder, they worked with me in regards to the bill I still owed. I appreciate their patience and understanding on paying my account off. I had to use a large part of my tax refund to pay for a family member’s funeral. I am forever grateful that they have worked with me during this difficult time. Their efforts and understanding will not go unnoticed.

Advanced Heating & Air
Excellent!! Advanced repaired my heat with no problem. Called in on a Tuesday night. It was a chilly night and they came out right away, no questions asked. The service man was very polite. He had to add freon to my heat pump and replace a part in my indoor heater section. He had the parts he needed on his van. I felt very comfortable with this company and will definitely call them again if I have any heating or a/c needs. I'm rating them with 5 stars and would recommend.

Advanced Heating & Air
WOULD RECOMMEND TO ANYONE!! Researched several companies through BBB and Angie's list, etc. Advanced definitely lived up to their good reviews. Very professional from beginning to end. Treated me and my home with respect. Neat, wore shoe covers ( my wife loved that) and price was very reasonable which was the replacement of an outdoor fan motor that was bad. We signed up for their yearly maintenance program. Very pleased with our entire experience!!

Called on Friday for next Monday service and I was grateful for them to squeeze me in. He grabbed a new part from his truck for my AC unit and fixed the small problem even though we didn't ask/expect him to as we ordered the service call for inspection only. He could have not done anything and waited for us to call him back for another service call. I'd recommend their service

Advanced Heating & Air
Great experience!! We had our heat pump replaced by Advanced. We purchased a higher efficiency Carrier heat pump. The install crew was very courteous and cleaned up their work area nicely. I also had my duct system cleaned the same day and it has really seemed to make a difference. I will definetly recommend Advanced Heating and Air to my family and neighbors.
Tips & Advices
You can keep your air conditioner running efficiently with some preventative care measures. Shut off the power to your AC before cleaning it or performing any of these tasks:  clean your filter at least twice a year; remove leaves and twigs from cages; clean the fins with a garden hose or special spray, then use a butter knife to straighten any that are crooked; keep your yard clean so the fins won't get blocked; cover the unit up for winter; and make sure it's level or you run the risk of damaging the inner workings of the unit.
To clean your air conditioner drain, first shut off the power to your unit at both the thermostat and the breaker. Then remove the drain pan. If the pan is full of water, soak up the liquid with a few towels or rags or use a wet vacuum. You can use a solution of water and distilled vinegar, or substitute peroxide for the vinegar, to clean out the drain pipe. Let the pipe sit for a while in the solution and then put all the parts back in place. Once you start using your air conditioner on a regular basis, check it periodically to ensure condensation isn't building up.
If you happen to live in a hot and humid area of the country, drainage problems can occur with your unit since moisture can trap itself inside the system. Routine maintenance can cut down on drainage issues by cleaning out any mold or algae from blocking the drain. If you notice moldy smells whenever you turn the thermostat down, check on your system.
If you notice your system is acting inconsistently, the sensor is most likely out of place. Turn off the unit and reach behind its control panel while carefully bending the sensor back into place near the evaporative coil.
Find out where the noises are coming from. A banging or clanking sound could be due to a loose part. If you hear a hissing sound, it's most likely because of a refrigerant leak and you should contact an HVAC technician as soon as possible.
