The technician Shawn was very knowledgeable and explained everything as he went through the process of repairing our AC unit after the storm on July 3 2026.
Thank You to the Jett’s Team“

“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!“

“McHenry Heating and Air has been my first choice HVAC and Plumbing for my home and rental properties. I tried many in the area before them and they are the best and have been using them for last several years. Recently had an HVAC emergency call at 10 pm and technician worked until 2 am to get the furnace going. Service calls and installations have always been affordable and they can't be beat with how they back up what they do. Same for the plumbing side of the business which I also call them for (wish plumbing had weekend hours but you can't have everything).“

“Patrick is great! We recently had a new system installed and needed to put in a service call. They were able to fit us in the same day and communicated clearly before his arrival. Patrick was friendly, knowledgeable, and quickly diagnosed and fixed the problem. Excellent service all around.“

“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!!“

“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.“

“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!“

“Quick response replaced thermostat and tested, was a bit pricey, but was friendly and helpful.“

“From receiving proposals from Jeff, discussing with Kris, and excellent installation from Evan and Collin the process for a new HVAC system was seamless!“

“Everything Mechanical installed my complete HVAC system about 4 years ago. I'm a retired Industrial Maintenance Superintendent and solicited quotes from many local HVAC companies. They all wanted to sell me equipment that I didn't want at ridiculous prices. Everything Mechanical got me the system that I wanted, at a fantastic price, with a 10-year warranty. Today that system had issues caused by spiders, getting into the system, and causing 2 parts to fail. Not the 1st time I've seen it happen before. I contacted Dan, at 7pm, for an emergency service call, as the temperature, in my house, when I returned home was 84 degrees. By 8:15 he had one of his service technicians, Kyle, at my house. Kyle diagnosed the problems, had the parts in his company service vehicle , and my unit was running, like a champ, by 9pm. Absolutely top notch service! I couldn't have asked for better. Kyle was friendly, knowledgeable, efficient, and made sure that everything was cooling, as it should, before going to the his next service call. He treated me, not just like another customer, but like family! Everything Mechanical definitely takes care of their customers with great service. I'm so happy that I went with them for my HVAC system! It's not just the sale of a system, but the service, afterwards, that makes them a great company. I highly recommend them because of that. Thank you so much Dan, and Kyle! I'm one very happy customer!“

“Prompt, efficient, and professional services...Couldn't ask for any more. Thanks Chad!“

“The technician was great and communication with the company was easy as well. They have very reasonable pricing and are not trying to ripped you off for sure.“

“My heat was completely out.
Ray came and got the job done! I truly appreciate the quick service and Ray's knowledge throughout the repair.
I highly recommend American comfort.“

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

“I left to go on a fishing trip in Canada and my furnace went out so the A/C couldn't blow and S&R put a new unit it in while I was gone and I came home to a nice cool house on a 98° day. Thank you!“

“Met owner. Very nice person. Loud Brothers were highly recommended! Poor Richard of the Town Planner“

“We are absolutely thrilled with our new roof! After hail damage to our roof, All Star was a pleasure to work with throughout the entire process. They made navigating the insurance claim process and installation painless! I highly recommend All Star!“

“Jerimiah came out within 2 days of being contacted and fixed a problem immediately that 3 other technicians from 3 other companies could not solve for me. He was friendly and knowledgeable. He not only fixed the problem in under an hour, he explained the issue in detail to me and what he was doing to remedy it, also in detail. The price was fair and I couldn't recommend him more!“

“I couldn't be more pleased with my experience with Combined Services. From the moment I called, their customer service was outstanding—friendly, professional, and quick to respond. The technician arrived on time, was incredibly knowledgeable, and took the time to explain everything in a way that I could understand. They diagnosed the issue with my AC unit quickly and had it up and running again in no time. What really impressed me was their honesty—no upselling or unnecessary repairs, just straightforward, quality service at a fair price. It's clear that they care about their customers and take pride in their work. I highly recommend Combined Services to anyone looking for reliable and trustworthy heating and cooling services. I’ll definitely be calling them again for future maintenance!

ALSO… do yourself a favor and talk with Ken!! I had the pleasure of working with Ken, the owner, and I can’t say enough great things about him. From start to finish, he was professional, knowledgeable, and genuinely cared about getting the job done right.“

“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!“
