Heating & Air Conditioning / HVAC near Round Lake

“Christopher was detail oriented and made sure he checked everything. The A/c is only four months old but he quickly identified a leak in the system. He also brought other items to my attention that were really important. I feel at my age (80) it is really important to have a maintenance contract on this important piece of equipment and Christopher cemented my decision to keep it going.“

“Wow, Dave is fantastic! Our furnace stopped working on this cold February night and he was so quick to help! Great, honest guy! Thank you! We will use Biermann to service/clean our furnace in the future!“

“Ken and Juan did a great job. They are welcome back to our house anytime. Thanks for their service. Happy Holidays to all.“

“Above and beyond service. A/C stopped working Friday afternoon. Called and asked if someone could come out early Saturday due to the heat and elderly family members needing to have the cool air.

Service tech arrived early Saturday. Diagnosed and fixed the unit in under 30 minutes taking extra time to rinse the coils and change the filter.

Would highly recommend using Command Service !“

“Bryan Gomez came out, did a fantastic job explained everything and was super professional and friendly.“

“Overall excellent. Not referring to today's visit, I understand that companies have limits on services but they could be explained to the customer in friendlier tones of voice.“

“July 2,2026
I called Keith at Premier Heating & Cooling because my air conditioning wasn't working.
Keith came out a little later that evening. He took care of the problem. I am in AWE!! I appreciate Premier Heating 7 Cooling!“

“The technician Ulises G at Kwik Serv Plumbing is very knowledgeable, polite, and will explain everything in detail about how he fixed your plumbing problem. He has fixed two issues I had and I truly enjoyed each conversation. Thank you Kwik for hiring such a wonderful licensed technician.“

“Connor and Kevin installed our new hot water heater on Monday after I made an emergency call on Saturday that the old one was leaking, etc. Joe was out within a couple hours on Saturday to assess the situation after Emily had contacted him. They ordered a new hot water heater and had it installed as promised by Monday. Connor and Kevin did an amazing job and were very kind and informative. Once again, I can't say enough about the service and professionalism of this company. I would highly recommend them. Thank you for taking care of us so quickly!“

“So my AC went out last night, Steve came by 30 minutes after I called him which these days is quite unusual especially at night. Unfortunately it was dead, but came here at 8:00 Am today and installed a brand new one. Talked to me entire time explained everything that he was doing and did a fantastic job. Not only did he do a great job, he is a legit a very good guy, and glad I reached out to him. I highly recommend calling steve if you have any issues with your AC. One of the few good guys left that you know that you can trust and to be honest

“An absolute pleasure to work with! Jason went above and beyond to get my air conditioning up and running quickly and efficiently. I highly recommend Comfort Doctors!!“

“I could not be happier with American Comfort Solution. We had a stressful situation where another contractor accidentally pierced our radiant floor heating tube, causing a leak. I first called a plumber, who charged $200 for the service call AND I realized quickly when the dispatched plumber arrived that he didn’t seem to know what he was doing. He tried to hit me with what felt like predatory pricing—quoting $1,000−$2,500 on top of the service call fee.

I decided to get another opinion and called American Comfort Solution (recommended by gemini). I was able to speak with William directly and he gave me a rough quote right over the phone, which confirmed that the plumber was trying to take advantage of me. William and Mike came by later that week and quickly fixed the leak for just $236 total, with no service call fees.

Because of that great experience, I had them come back the following week to install a Heat/AC system in my finished barn and service our existing AC units. All their pricing was incredibly fair, and they were super easy to work with and schedule. They were even able to efficiently knock out a lot of extra things while on the same service call. I will absolutely be using them going forward (they are in fact coming back later this week for more work). I’m thrilled to have a reliable, honest HVAC team here in Salem!“

“Adam and Fernando just finished cleaning my air ducts. I have to say they did an amazing job they were very thorough and professional. They explained everything they were doing step by step during and gave before and after picture. Great Job!!“

“I had an intermittent problem with my boiler. In less than an hour after calling LCM, Robbie was at my house to diagnose the issue, and had it repaired. I’ve used this company a couple of times in the last year. I would highly recommend them.“

“Thank you Kyle and everyone at Beckman Bros. for the amazing service! I now have much needed AC and am confident I'll be warm this winter. Kyle did a great job explaining everything to me and did a great job 😁“

“It started with an amazing experience with Jen who did the scheduling. Extremely costumer services focused. Quinn and Davion were wonderful. I highly recommend for any needs you may have.“

“I have been using Maki for over 20 years. They have taken really good care of us. Would highly recommend them.“

“Chase Martin came out on a Sunday for an emergency call on one of the hottest weekends of the 2023 summer. He found that the blower on the furnace had failed. Being a holiday weekend, the part could not be found until Tuesday. Chase gave me ideas on how to keep the house cool and carried my very heavy dehumidifier up the stairs to help my living room feel cooler. He was conscientious, kind and apologetic that he couldn't help me right away.“

“Good experience, I had booked a maintenance appt during the extreme heat and Omar texted just to check if my A/C was currently working. That was very considerate and much appreciated.
Cesar did a great job at the appointment explained everything to me, along with my different options today and moving forward.“

“Been dealing with Bob and Air-Tech since 1997. From the initial AC install then to a complete HVAC replacement in 2021 and any maintenance/repairs in between I couldn't get anything better. Great service and prices and no BS. Would highly recommend!“

“This morning we called Mr. Heatmizer because our A/C was not always keeping the temperature as set. Patrick answered the phone and was very good at asking questions to troubleshoot. A few hours later Nick called and said he could be on his way here. He drove through major road (no road left today!) construction in and out of our driveway. He then quickly and accurately found the issue, explained it clearly with pricing. We have been helped by this company previously and highly recommend them! Thank you Mr. Heatmizer!“

“We needed a new AC and Tritan was so professional, timely, and affordable. I would use them again and recommend their services to everyone!“

“Always on time, handles the work efficiently and always with a smile. Courteous and reliable service for many years now. I wouldn’t use anyone else“

“Was in a pinch and made calls to everyone.. Joe showed up immediately. Troubleshot my entire system and in short time had my family in-service immediately.“

“We had Thornton service our dehumidification system for our indoor pool, and I couldn’t be happier with the experience. Nick was incredibly responsive and went above and beyond to squeeze us into their schedule so that the pool would be ready in time for an important graduation party we were hosting.

The compressor was replaced and system tuned up to the specs, and the space feels great. If you’re looking for a professional and reliable team to handle HVAC or dehumidification for an indoor pool, I highly recommend Thornton HVAC. Excellent service and a great team to work with!“

“The workers who arrived to my home were polite, introduced themselves with their names and got to work. The work was done much quicker then I anticipated and I had brand new duct work and was running heat once again. Happy to use a company that a friend recommended based on his positive experience and will refer this company to any friend who needs HVAC work.“

“Great service! Whole ac system replaced at a great price. He also installed our smart thermostat for us. Very friendly!“
