EXCELLENT company!!!! John Polermi is the person I worked with and he and his team did a great job. This company installed a new home heating system for me and a new air conditioning part. They were reliable, professional, fairly priced and left the work area spotless after a major installation. I give this company my highest recommendation.

Good professional service , knowledgeable about heating and air conditioners and reasonable prices

Browns heating and cooling quickly resolved the problem with our ac and at a fair price. Prompt and professional. We will use them again should we need a heating and air professional.

Jason was excellent I was without heat on the coldest day of the year & waited all day for Four Seasons to arrive to install new boiler when they finally showed up at 5:30pm they were trying to charge me a price of over $6000 for a boiler that is advertised for $3600 because it was so cold out & we were desperate to get heat. I could not agree with that I called Jason from COMFORT AIR he came to my house 7:30pm checked all my radiators & the boiler Four Seasons was gonna install was not the proper size for my house so I will recommend COMFORT AIR THEY ARE GREAT I FEEL THEY ARE CARING & HONEST I'm really thank God I called him. I will HIGHLY recommend THIS COMPANY.

June 17, 2016 Annie D. For the past 3 weeks I have been without my central air system, and although I had gotten many estimates from several individuals I was not comfortable with the interaction and lack of information that I received. And as a last resort I went on-line to do some research and got in contact with Mr. Thorson, and some how, some way, he imparted such peace and reliance to me. That, on Friday, 6/17/16, Dave and two of his crew came to my home and installed my central air system. The professionalism, understanding, and care that was shown made us realize that there are still decent, honest tradesmen around, who are not out to deceive others despite the lack of knowledge we have of the different trade source we do have need for. I will always refer to, rely on, and trust Dave for future help and advise of his professionalism, knowledge, honesty, and most of all the care he imparts for others. Thanks guys!!!!

Steve the owner is amazing!!! We had a new furnace, humidifier, AC, and hot water tank installed. Steve's pricing was very reasonable. The workers did an excellent job, left the job site clean, and finished when they projected. Steve had the job done the day after we had hired him for the job. We are so impressed with the company and highly recommend. Steve is very professional and knowledgeable. Can't say enough about this company and our experience with them - we are extremely satisfied!

My secondary air conditioning unit failed. They were quick to respond and came out the same day. The accurately assessed the issue, and gave me a number of options including fixing or buying new, at different price points. When I chose to fix the issue, they clearly explained the risks, but respected my decision. They followed up on the technicians work. While they had to order a part, they quickly installed and got the right bit working as soon as it arrived. The unit has been working great for the last month. I would definitely use them again.

JNT replaced an air conditioning unit on short notice. They did an excellent job and did great follow up. I would recommend their services.

As a top real estate agent, I rely on other experts who are honest, reliable, perform quality work, and are reasonably priced. Robert comes highly recommended for any heating and air conditioning service/installation needed. For years, he has worked with many of my buyers/sellers and on my personal properties. Most recently an A/C installation. Thanks Robert!

The repair Technician, Miguel Vargas, responded to my call for water heater repair on a Sunday and was able to get the water heater functioning in the interim period while the part that needed to be replaced was on order. They turned this around in 24 hours and my water heater was fully repaired. Miguel was friendly and explained the issue fully to me. The pricing was fair and the work was done expeditiously. I would highly recommend him and All-4Climates, for Heating, Cooling and Water Heater issues.

Reagan did an amazing job with my air conditioning cooling project. He is the kind of handyman professional that anyone would like to have as their "Go To Guy." He can handle virtually any project without costing an arm and a leg. He even supplied the material - which meant no hustle or bustle for me. Once he gets started on your job, he works continuously. I was sure that I was going to have to spend time helping him with the project - but I did not and it was worry free He said, "no worries" I have it all under control." He was even able to cart the old condenser away. I will definitely request Reagan for all of my future home improvement projects!!! Reagan is someone that I knew instantly was a man of integrity and worthy of my trust. I didn't feel the need to hover or hide the family jewels. I wish all contractors were like Reagan!!! So, please hire Reagan for your home improvement projects, but I can tell you right now he will be unavailable, if I have my druthers, because the very next time that I have a home improvement project He will be my "Go To Guy!!!"
