If anyone is in need of Heat and/or A/C repair, Graham Mechanical & HVAC is the company to call. I…read morehad another company come out and was told I needed a whole new unit that would cost me right under $10k. I called Graham Mechanical for a second opinion. Dale correctly diagnosed the problem and had my A/C up in running in no time, and the cost was extremely fair. He was professional, honest, and happy to help me. Let me just say, he saved me well over $9k dollars. Thank you Dale

I told Dale that I work in the evening and asked if he could come by around 2 to 3 pm and he agreed…read moreto show up between 2 and 3.

We found Reliable Air on Google as we searched for afterhours service realizing there would be an upcharge. At 6:30pm, I placed a call to Reliable and left a message for Michael.

The technician (Golden) was pleasant and seemed knowledgeable. He wore a mask whole time. Heat was working when he left but he said he really didn't find anything that was conclusively making it not work so he tightened connections. He discovered another issue that needed attention and got me scheduled for them to come back early next week. The next week comes and the day they are to come the heater goes out again during the night. I phone that morning again and the person is again pleasant and easy to deal with. He says they will have that added to ticket. He calls back and says he can actually get someone out sooner if I would like. New tech (Mark) was wonderful. He wore a mask while here. Very personable and knowledgeable. He apologized that wouldn't be able to get all the work done today as one of the machines had broke and the company was waiting on replacement. He answered questions that husband had that I couldn't answer from first visit. He said he found problem but was lucky it acted up while here. He serviced machine under CSA and said the other work would be rescheduled when the machine they were waiting on arrived. This company goes all out to ensure you are happy and satisfied. Work is first class as are the employees.

This company deserves a special rating of ZERO STARS. This job was so horribly botched that you…read morecould not make this up!!! I paid Richard Tattershall's company, Comfort Class (known in many forms as Comfort Class, C&C Air Services, C&C Chimney, etc.) $20,845 to replace 3 aging HVAC units in my home. I signed a contract stating that the installation would take 4 days, and I (like any reasonable person) signed that contract under the assumption that the units would be properly installed. Oh boy was I wrong! Long story short, not only did the installation take significantly longer than contracted (to the tune of 11 days, not 4) people have been in my home *30 times* (yes we are counting) since the "completion" of this installation. 21 (also counting) of them were unit failures, the latest being June 22-28 - yes, during the hottest part of the summer so far, Richard and his company allowed our A/C to be inoperable for 6 days. Read on to find out about the part where I had to go through a ton of hoops to find and then file a claim against this company's insurance. This company completely failed me as a customer, left me with water damage to my home and personal property, and ALL THREE *NEW* furnaces they installed failed multiple times within the first month of their operation and continued to fail as far as 9 months afterward, so far. As of this writing the most recent failure was less than two weeks ago. How exactly did this company fail us? Let's make an incomplete list: - Installation went so poorly that before it was even finished, an employee quit the company and came to my home with CO detectors warning me not to use the furnaces due to the risk of CO poisoning - Did not convert the units from gas to propane until 1 1/2 weeks after the install and after all 3 units had been running - Failed twice to seal a hole in the house left by a pipe C&C removed, leading to thousands of dollars in water damage the company attempted to ghost us over instead of making an insurance claim - 7+ failures within 1 1/2 months, ~21 total failures out as far as 9 months - After one failure, Dale & Lee's service came and inspected the units and gave me a pink slip (see the pink photo) warning me against running the units until they were inspected/repaired - the second HVAC professional to warn me of CO poisoning if I use these units! - Totally botched install: a double "P" trap, pipes left unglued, zip-tied drain lines, improper wiring, an unlevel unit held up by straps and PVC pipe (that one had about a 25% airflow restriction initially) - Install began on Nov. 11th, we paid for the "completed" job on Nov. 22, last furnace failure was 1 week before we turned them off for the spring - We had to have a lawyer send them a demand letter to get one of our failed units fixed after the company ghosted us in the middle of the winter right after they found out how much the water damage would cost to rectify Through this terrible process, this company has established a pattern of incompetence from the bottom all the way to the top, and a complete abdication of responsibility when faced with the expense of their mistakes. Richard promised refunds multiple times, which I never received. They promised a resolution to my property damage, which I never received either. To finally be compensated for the property damage, I had to contact the Oklahoma Construction Industries board, obtain a copy of this company's Certificate of Insurance, and call them and submit a claim myself. For anyone wondering, the insurance company accepted and paid the claim. The icing on this cake is the most recent failure we experienced. When our units failed on June 22nd, C&C sent ASAP Heating and Air to fix it. The ASAP rep took one look at our failed unit and told us he would not touch it. After taking pictures and talking to his superiors, he notified us that his company would not be willing to take on the liability of the poorly-installed unit, saying that it needed to be completely reinstalled (see the ASAP invoice photo). Richard lied to make the sale, saying the units they were installing in our home were the "same exact ones" they trained on. In reality, he sold us units his company had never installed, and we didn't find that out until after the install began. They made us pay for their training, left us with damage to our home and our personal property, and refused to answer our calls when one of our units failed yet again. TL;DR: We paid for a proper 4-day install of brand new units. We got an 11-day install, 21 unit failures in the 9 months since, an insurance payout we initiated ourselves for water damage, and proof that our units still are not properly installed. Oh, and accusations of wrongdoing on our part. This has by far been the worst experience I have had with any company, ever, and it just keeps getting worse! I would not recommend them, even to someone I dislike. You've been warned!
