Recommended Customer Reviews

Do not ever use this company. They are a scam.
Found ac not cooling upon arrival due to several factors. The condenser was not coming on due to a tripped float switch in
the secondary pan caused by an apparent clogged primary drain line. Inspected equipment and found the contactor badly
burnt and pitted and the start capacitor blown in the outdoor unit. The liquid line drier was also badly rusted and in danger
of leaking freon. The condenser coils are badly oxidized and deteriorated and the compressor amps are very high, close to
maxed out. Due to the age of the equipment (19 years old), the refrigerant type which is obsolete (R22), and the condition of
the equipment (poor), I determined that it would be better to replace the system than to repair it. However, if the customer
wants to repair it it can be repaired. Although I can't guarantee the life of the unit. And due to new EPA laws and rising costs
of HVAC equipment, my recommendation is to replace it. Discussed this with the customer but she was not happy with my
recommendation and did not want to replace the equipment. Offered her temporary repair option but she declined.
The condenser was not coming on becaure he shut of all the breakers. \
( Bradon shut of all my breakers) I asked him to use a dry vac to unlogged the drain. He said it would cost 1000$. I did it in 5 mins. I know my unit is old. He did offer me a price of 15,000 at 9.5 % intrest at for 5 years for a new AC. My credt score is 845?
I am going to report the company to the BBB. Then I had a new company come over and they sad not is worng with the unit . I just need to drain pan. Now my ac is working great..

What a sham business...i have a routine service agreement with these guys to check my unit 2 times a year which also includes any other service calls at a discounted rate. So, needless to say, i had a concern with my condenser fan motor making noise. Called out a technician, great guy, he verified the fan motor was getting stiff so i decided best to replace it. He had an off brand on the truck in the size i needed so i said lets replace it. When he returned from the truck with the motor and showed me the price, I about lost my mind! $1100 for his motor that i also coincidently looked up on line for a reference price that would cost me $200 if i purchase myself?!?!? I kindly told the technician to leave, paid him for the service call, and told him to let his management know they will surely loose my business with these shenanigans! I ordered the direct OEM replacement online and will fix it myself!

Charged us $700 plus for a recharge
To their credit they came out after dark on a Friday so I guess $700 for the weekend
My wife was home alone and repair guy was all about selling wife a new system
Got another locally owned company ( owner too busy and wishes to remain anonymous) to come solve our problems for a reasonable rate without replacing entire system
I asked wife not to call DR Jekyl Mr Hyde again

Do not use this company if you want quality work done or good customer service. My husband started work with this company in a new installation at the end of May. This was based on the good reviews and the excellent service from the man who came out to quote the work. We were sold a Cadillac system and so far we've gotten a pinto. The installers, quality rep, senior installers and now the quality rep again have been out no less than 8 times. Each time my husband has had to show the installers where work was not done. We got new ducts run that were left pinched and sitting on attic beams. One duct was not touched and was running into open wall space. The system wasn't cooling any better or blowing any more air than our nearly 25 year old unit that was taken out. The customer service rep I personally spoke with and who spoke with my husband was more interested in getting the full payment than addressing my concerns. Her attitude when the issues were explained was poor at best and frankly condescending. This is a no go place as far as I'm concerned and if a zero star was possible I would do that. The quality rep has been the most helpful in this entire process.

As y'all know its been brutally hot so 1 of our ac units gave up the ghost. These folks came out and said it needed a 45+5 capacitor about $40 at HD.
I asked him what the price for the capacitor he said $575 and $185 but they would not waive call fee even though most honest people waive the fee or reduce it. Not here the drive out was $827 for 30 min work. Folks if you will check other yelp comments you will see about their flim flam game. The tech was a very nice and knowledgeable person just doing his job and he said his hands were tied by company policy. I would not recommend them to do anything because of their price gouging

I purchased a property and was told by previous owner that the warranty was transferrable to new owner (me) - Upon trying to get the warranty transferred both the prior owner and I were told that the warranty was NOT transferrable... although the prior owner had been told so at time they purchased the unit -
First I was informed that it was not transferrable due to the unit being a 'commercial' unit.... Seemed odd that a property that is less than 1200 sq ft would require a commercial unit so when I asked what made the unit 'commercial' was then told 'well, it wasn't really commercial but a special order' - Rather than apologizing for giving out misinformation when the unit was purchased by claiming it was warrantied when it wasn't, this individual went on to say it wasn't Doc Cool's fault that they hadn't understood that the unit would not be warrantied.... The person I was speaking with at Doc Cool repeatedly said 'How is this our fault?' .... Were they implying it was the purchaser's fault for believing their claim that they made?
It just seems that if a reputable company makes a false claim, knowingly or not, they would honor their claim.... and take a chance that the product was a quality product that would not break down for what is not a significant time left on the warranty -

These guys installed my AC system and maintain it annually. They do a great job and also take the time to remind you of upcoming required services. Their appointments are given as a window and you are given a final "" I am on the way"" 30!minutes before they arrive. Great service!

They damage your ac and tell you it needs repair. I have the service contract. My ac works fine before they come in. Mysteriously, they find something damaged like a cut wire, a low freon. They tell me system is old, it needs to be replaced. It will cost more to repair it. I even saw someone releasing the freon then he told me my Freon was low. I asked him why he released some freon. He was surprised that I knew, so he recharged it and told me it was not that low, so he did not charge me. I then found out much later that what he did was illegal (releasing the freon). Watch those techs like a hawk, otherwise they will damage your ac and then charge you for repair.

I called the company on August 30th because my A/C has stopped. Technician came could not find any issue. I asked technician if the circuit board can be changed, he said no, the whole unit needs to be changed because it is old over 23 years old. He did not check the electric box for the unit. The A/C started working without the technician help.
On September 8th, the A/C stopped working again. Technician came. Started the A/C. Charged for turning the switch on 49 dollars.
Few days later the A/C stopped working. I called an electric company and the company found the electric box wires above/next the compressor was loose.
I am asking refund for the 2 times charges. Thanks

The entire team at Dr Cool & Professor Heat were amazing. Sakis, the engineering tech surveyed our existing system thoroughly and listened to my concerns.(noise and hot areas in the house) He calculated the heat load on our house after getting our input on what our comfort temp was and took into account our building's structure, insulation level, and windows type. He gave us a quote on a new AC/ Heating system with an innovative solution to address our problems with cooling/heating our East/West facing 3 story town home quietly and evenly; and explained everything that they would do, how long it would take and what to expect. None of the other companies that I got bids from wanted to do anything beyond just replacing my system with another one just like it (only 20 years newer). Putting in an energy efficient system was important to me because we plan to live here long term. Sakis quoted a heat pump system that has one of the highest SEER ratings and qualifies for the maximum federal tax credit, which made it very cost effective. It also has the most impressive warranty out there. The installation crew (Paul, Joseph & Michael) did a great job -they even left my attic more organized than they found it! They were careful to clean up each day before they left and coordinated taking out the old system and putting in the new one with just a few hours without AC. They balanced the flow to the 3 stories by adding additional registers / vents and air returns. When they were finished, we had an issue with the thermostat not controlling the temperature very tightly.
Brandon, the service manager came out promptly and took care of that problem. When they were all done, we had a system that is so quiet and efficient , I have to go outside and look at the fan to see if it's running!
