“Total lifesaver. Tried troubleshooting the thermostat based on YouTube videos. Nothing worked. Desperate in the heat wave and getting ready for my wedding in a few days I made panicked phone calls to everyone I could find on yelp. The first 6 calls gave me the same response: it’s a heat wave. We are booked til next Thursday.
Krystal actually calmed me down and said she’d get someone out in 2 hours. The tech called that he was available earlier. Yes and thank you! Turns out it was as simple as a filter!! He was EARLY. Not just prompt. EARLY!! Gotta love that they took my emergency to heart and saved the day. They’ve earned my loyalty.”

“Called in am and got an afternoon appt. I am a first time customer and was pleased with the courteous and quick service. Tech was able to come earlier than scheduled time which I was happy about! Tech Eric was so professional and courteous. Finished repair needed quickly and answered all my questions. I definitely recommend this company for service needs.”
– Suzanne A.
“Excellent service. During the heat wave while another 10 A/C companies were too busy to come out, CC was able to fix our unit within a couple days. We asked for a follow up visit and Mike S. came out to answer all my questions and more. He even went up into the attic to evaluate all my piping. To say Mike went above and beyond is an understatement. Highly recommend this company for your AC needs.”
– Tom B.
“Extremely satisfied with the customer service and level of quality from these guys, from the estimate to the execution of the job… They were the only ones responsive to my Yelp inquiries during which I’m sure was a busy heatwave season, and gave reasonable pricing among different tier options… When they came they were super friendly, clean, and quick. They even neatly trimmed the side of a tree for me that would have otherwise been obstructing airflow for the unit. The whole process was as painless as can be… I would definitely recommend!”
– Michael A.
“Very efficient and responsive service. Didn’t try to scare us and didn’t get to convince me I needed. 10k unit off the bat. Did an evaluation for free. Honest and professional. 5 stars for sure.”
– Drew H.
“5 stars. Need I say more? If you need HVAC work done, look no further than complete comfort heating and air.”
– Evan H.
“Mike was super helpful to help us fixing our AC during a busiest hot summer day. We had a broken AC unit last week. It can happen anytime during a hot summer day, and usually, I am okay to wait for a few days to get it fixed. However, having a broken AC with a newborn in my house was a totally different story. I had to call 16 different places to get help, but none of them could help me during their busiest summer day. Krystal and Mike was awesome enough to fix our AC as soon as I called them. It only took a few hours before Mike to fix the AC unit. He was very professional, and called out all the possible problems and explained why and how. Then he fixed it all. Instead of fixing and take off right away, Mike stayed around in the yard to see everything works properly to make sure there are no further problems. I definitely recommend them to everyone. I’ll totally reach out to them again whenever I need a help with my AC unit.
Thank you Mike and Krystal for your help!”

“From diagnostic, to quote, through review of many quotes, to the decision, to the install, everyone at Complete Comfort made this a successful project. My unit was 23 years and the season is heating up, the whole team helped me feel comfortable with making this big purchase decision. Eric gave the initial diagnostic and quote. Krystal followed with an official quote and answered ALL (there were many) my questions as I reviewed several other quotes and options. Eric and his crew did an impeccable install, it is day 1 of having working air again, but with all the warranties I feel secure about my decision to name Complete Comfort. Thank you!”
– Stephanie C.
“Great experience – Eric arrived at the scheduled time and methodically worked through troubleshooting an issue with the thermostat not initiating heating or cooling. Turned out to be a quick and easy fix and I was able to get back up and running with just the dispatch/diagnosis fee. I’m skeptical of most HVAC companies having seen more than one try to rip off friends and family but I’m off to a good start with Complete Comfort.”
– Mike N.
“Complete Comfort Heating and Air made the process of replacing our air conditioner and ducting so easy and stress-free. Krystal in the office was friendly and helpful. She always returned calls or emails in a timely manner. She was more than willing to update our quote as our needs changed. The installation went smoothly and was done in the time frame they provided. They caused very little disruption to our house and went above and beyond to clean up afterwards. Eric was great and very respectful and knowledgeable! We look forward to working with everyone again as we maintain our AC unit. I would highly recommend this company for your heating and air conditioning needs!”
