“Just thought I’d share that after having our new systems installed, we saved appox $100 between last month and this month with PEC!!!! And that’s without any rebate applied!!!! Thank you! :)”
Cathy Lyman

“We received a new AC/heat unit from your company in late October and were very impressed with the complete deal – – explanation, quote, installation guys, and cleanup. The quality we received from your guys is obviously repeated many times. I am forwarding this email to several of our family and friends who live in the Austin/San Antonio area should they need service. Best wishes for a great year in 2011. Companies that “say what they’ll do, then do what they say” aren’t always easy to locate”
Dan and Laurie Stevens, west San Antonio

“I hired Dayton AC & Heat to replace my home air conditioner and furnace September 14, 2010. I got bids from half a dozen local companies, but found Coy Dayton the most professional and honest and I felt he did the best job of identifying my needs. During my research period Coy fielded at least half a dozen of my phone calls answering all my questions credibly and even gave me the number of the local manufacturer’s representative to confirm warranty questions I had. I hired Dayton AC & Heat because they offered the best price and warranty combination. Installation went well and the installers were fast, professional and friendly. After installation a service technician came by to ensure that everything was operating smoothly and that I was completely satisfied. I highly recommend Dayton AC & Heating.”

Tom Sandage

“I just would like to thank you and your company for replacing my A/C. After experiencing less than ideal customer service from other companies I had my concerns about all. But after talking with Robert “Bobby” Wagner about my A/C and actually seeing the condition of the coil prior to the replacement. Then returning home after the replacement and seeing the difference, I wish I could explain my amazement. Can you please ensure that Bobby knows how much I appreciate his work and that he restored my faith in companies like yours. I would also like to apologize for any disbelief on my part because he removed those also. I have no problem recommending your company. Thanks for everything. “

Stanley Rasberry

“We are so pleased with the job y’all did that I would like to give you a very positive rating. If you know how I would go about doing that, please let me know so that I can share with others the fantastic job you guys did. :0)”

Dr. Kat Sandler

“Can’t tell you enough how impressed I was you the guys who installed the a/c units today. They were so nice and worked non-stop until the job was done. Keep up the good work. Hope to do business with you again, but not too soon…….:)”

Judy Hopson

“Hi, Roy. Sorry to be late in replying. I loved Coy and his crew! They were honest, diligent, and expertly installed my Amana system, and cleaned up afterward. They also redid my duct work at a wonderful price. With the Amana, if Coy is still able to offer it, I also received a ten year warranty not just on parts, but also labor, which is a great value.

I’m not familiar with the “comfortnet” term. I’ll have to ask Coy what he installed for me. I’ve had the unit a year now and am very pleased with my overall savings. “


“FYI, I looked up the other bids. Yours was $300 under the next higher bid; the highest bid was $10,000, after everything was equalized (rebates and manufacturer refunds). What sealed the bid for me was your approach— more business – like, and more transparent. That is, you answered all my questions and were more responsive than the others.

Thanks for your hard work (as well as your crew). If it’s ok with you, I’d like to write a positive review/comment on Angie’s List. Let me know.”


“With the Texas heat beating down, my call for service was handled promptly and they had the parts needed with them. With all the uncertainty we face in life, it is nice to know that with Dayton A/C & Heating, you can be certain that you will be taken care of!”

Von Beals

“Thanks so much for your great professionalism in biding and installing our new AC and furnace. Your crew (Bob, Ray, and Jarod) did a great job, going above and beyond to ensure our satisfaction! We really appreciated doing business with you, and look forward to a continuing relationship.”

Mark and Kathy

“I certainly would like to give Dayton A/C & Heating a reference. I couldn’t be more pleased. He is dependable and very interested in doing a great job. Their work is exemplary and always with what the customer has in mind. He is realistic and informative. I would never call anyone else.”

Rebecca L. Ponder

“First off, all is glorious. I woke up at 1:30 this morning and had to increase the temperature because I was freezing. This rarely happens to me. As well, I have never felt the upstairs so comfortable. I am glad we went with the dual system. There are so many wonderful things about the whole experience that I just don’t know where to begin. Let’s just say we are very happy. As well, your install crew was great. I am sure Susan messed with them during the day and when I got home, I continued. They were great and we made sure we fed them. The only problem was that they wouldn’t stop to eat until our A/C was running. We kept their sodas cold in the fridge and just left their burgers and fries in the garage to stay warm. I hope they enjoyed the meal.

You guys are fantastic and I hope the feedback we provided reflects that. Unfortunately, there was so much good to say about you guys and the rating pages for Service Magic severely limited my abundant rating offering.”

Tony Charboneau

“I am happy to support Dayton AC & Heating. I selected them initially because of their willingness to be detailed in their instalation. Their feedback to my questions were prompt and complete. We selected the best heat pump unit for my situation and to date, it has improved my quality of life indoors. I believe that what was important to me was their cooperation, flexibility and professionalism. They moreover assisted me with the paperwork needed for the State rebate. I know that if a problem arises in the future, I can count on them to take care of it promptly. For the aforementioned reasons, I am happy to recommend them without reservation.”

Dr. Arnold C. Vento

“My experience-
I needed to replace my AC system. Got quotes from 3 contractors including Dayton AC.
-Response time for quote was excellent.
-Dayton had the best price
-Work was done on the date scheduled and was completed on time, even ahead of the estimated time.
-New systems work great – no problems.
-Recommended Dayton to 2 of my friends.”


“In 2003 Dayton A/C & Heating installed my then new HVAC and everything about the installation was professional. Seven years later we still have an efficient and durable system. My contribution? I change the filters often, the way Coy told me to do.”

Mark Levbar

“I truly appreciate the quick response to schedule service appointments and the timeliness of all your techs. I also love the way that Coy and all the techs explain (in lay terms) what is wrong and have honest estimates of what needs to be done and the costs! Thank you, Dayton A/C!!”

Jennifer Appleton

“My experience with Dayton A/C & Heating was excellent. I was very satisfied with the prompt call regarding my service request and found the representative that came out to be professional and really tried to counsel me on options for repairing, replacing or buying a new unit. Thanks for everything.”

Pat Evans

“To all those who need AC/Heating servicing or for a new Amana product for home use no better service can be found than at Dayton A/C & Heating. They are knowledgeable and very easy to work with. I chose them for 2 new units this spring and have found them to have Great Products and Great Service.”
