Heating & Air Conditioning / HVAC near University City

“We have used Matheny for years, for all our maintenance needs. They’ve kept our units in great shape. When we did need them for repairs, They were there super fast and extremely fair! Highly recommend!!!“

“Tom was great . Appreciated his due diligence in identifying the problem as well as his professionalism.“

“We were in desperate need of getting our air conditioning unit evaluated. We called Academy Air and they were out the next day. We were sent a text to give us a heads up on the ETA. Jordan Richardson arrived on time and was very professional and polite from the moment he stepped in our door. Jordan gave us an excellent explanation of what was happening with our unit and a super helpful analogy. And when he was finished he explained everything very thoroughly. I could not be more pleased with his service and Academy as a whole. Double 5 stars for me!“

“They do a wonderful service and I am very much pleased with them! Recommend them to everyone“

“If it were possible, I'd give this job 4.5 stars. The electrician was great: friendly, knowledgeable, informative, and efficient. He was willing, if necessary, to stay late on a Friday afternoon to finish the job, but he was done well before EOB. So the only reason I didn't give the job five stars is that our discount as Home Protection subscribers seemed surprisingly small, ~$130 on a $900+ job. That's better than nothing, certainly, but given how much we spend every month and every year on the plan, I thought the discount would be a little more substantial.“

“Furnace went out on January 14 and my father called Kevin at Goldkamp, within 10 minutes I had a phone call from Goldkamp for a appointment to be set up the next day. Zac sent me a text and called saying he would be on his way in 10 minutes. Zac figure it out what was wrong with the furnace and was able to get it working and they were able to contact the warranty company and order a new part..Zac knew what he was dealing with. 100% trustworthy. My father got an air conditioner from goldkamp and was very pleased with his service. If you need somebody reliable and who can get you in quickly and know what they are doing call goldkamp. I know my neighbors use them also. Thank you goldkamp and all three dogs say thank you also now they are warm.“

“Tom, the technician, was kind, prompt. Fully explained and showed what the issues were and fixed what he said he would at the price he said he would. The work area was kept clean. Would definitely feel comfortable using them again.“

“Thank you for the service! I called on 12/4/25 and they sent out Technician, Ryan the same day. I am giving Ryan and the company this review because Ryan went above and beyond to repair my boiler issue. He was knowledgeable, concerned and very pleasant. He answered and gave input to my questions. I highly recommend this company and Ryan the technician to handle your heating & cooling needs.“

“Excellent customer service. Our very old furnace went out on Oct 29th and they had it replaced on Halloween. We went with a new unit but I appreciate that they did give us a repair quote as well. The installers were here right at 7:30 and completely cleaned up after themselves. Will definitely use them for any applicable needs in the future!“

“I called in the afternoon to schedule a technician and someone arrived at my house the next day by lunch time. I got a call ahead of time, a nice picture of my technician. He was veryyyy respectful and knowledgeable, he seen I was interested and chatted while he worked. I felt safe with him in my home. I called the office to give him a compliment & come to find out he is the OWNER!!! if the owner is that respectful , knowledgeable , humble etc , I can only imagine what amazing techs work underneath him. I did not feel like he was trying to hustle me with the price , I HAVE NEVER FELT THAT WAY BEING A WOMAN AND LIVING ALONE. He gave me a number as if I was a man. I appreciate that, I have to have my dad do most of my car maintenance for that issue. I will always use this company! Thanks Mike :)“

“Having to replace my HVAC during the hottest month of the year is less than ideal, however, Climate Masters was amazing at getting it installed quickly and restoring my house to a livable condition. The technicians were nice, respectful, and super efficient. I will never use anyone else. Thank you!“

“STH&AC were very responsive. From the initial phone call to diagnosis and maintenance on my AC they were thorough, professional, and friendly. A sout out to my technician, Austin, who did a great job explaining what was needed, what it would cost and recommending what I should do to keep my AC running well. In fact, I plan on using them this fall to do a check-up and any maintenance on my furnace.“

“Eric from Xcell Williams Heating & Cooling stopped by today. He got me signed up again for their seasonal maintenance special. As usual, he did an excellent job with my furnace maintenance. He was professional, thorough, and friendly. I love this company—they’re the best!“

“Glenn and his assistant did a fantastic job! On time, professional, and replaced our hot water heater quickly. Can’t thank them enough for coming out on CHRISTMAS Eve!“

“We just had Building Envelope Experts put in a large bay and 3 casements in our LR and DR. Fantastic! The windows are beautiful. Changes the whole look of the room. The installers are real craftsmen, going the extra mile that a 107 yr old home required to get the fit perfect. And they made the install as convenient as possible. Easy peasy. We also love the 3 glass block windows in the basement and 2 new doors. They put in 3 lovely doors 2 years ago that continue to exceed our expectations. That’s why we didn’t even bother to get quotes from any other company. I’ve done multiple rehabs and this company is by far the best!!!“

“Steve is an OUTSTANDING employee at Kirkwood Heating and Cooling. Steve is a very kind caring employee who took time to answer all of my questions regarding my operating system. Steve is a tremendous asset to the company as it is employees that make a company successful. The ladies in the office are also wonderful. They always manage to work scheduling out to accommodate the customer. I highly recommend Kirkwood Heating and Cooling for any of you needs.“

Craig walked us through our choices and best fits, and Ethan and Ky installed it and left without even a trace they were here. Everyone is friendly, polite, amicable, and professional. Great customer service from multiple experiences!“
