Heating & Air Conditioning / HVAC near Affton

“Fast service and high-quality work were evident throughout. The team was thorough, responsive, and displayed excellent communications at every stage.“

“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.“

“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.“

“Seliga is always prompt on time and professional. There technicians will answer all questions and perform excellent service.“

“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.“

“Aaron came to help install a new thermostat. He is always so friendly and good at what he does. We now have a thermostat that controls the AC without freezing us out.“

“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!“

“Matthew was on time and quickly did what was needed to check our furnace system. Very friendly and efficient.“

“I had nothing but great experience with Bart Inman Air Conditioning &Heat. They installed my entire system fast and with an extreme professionalism. Since the moment Ive called to make an appointment for a bid until the moment it was installed . They even did a follow up a month later. Came and looked at it to make sure that everything operates , and was done properly . Not to mention, they were a lot cheaper than the other companies Ive called. Their technicians are professional and polite. I have nothing , but good things to say about this company.“

“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!“

“They were excellent! From the beginning when using them for twice yearly maintenance to deciding when it was time to replace the 30 year old system. The new system choice was discussed & options explained. The day of the installation was seamless & Rich took time to explain the new system. The work space was SO clean. The “look” of the new system is impressive & very professional. We could not be happier.“

“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.“

“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.“

“Every person I've encountered here has been great. Nate helped us understand our outdated unit and need for an upgrade. 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!“

“Bill King was great—he diagnosed and fixed the problem quickly, explained things clearly, suggested additional neglected maintenance without being pushy, was friendly and courteous, and seemed genuinely to care about getting us what we needed at the lowest price possible. Great experience.“
