HVAC reviews in Addison, Illinois

Joshua was thorough with the inspection of the furnace. I felt he was honest with his explanation of the reason why the inducer motor needed replacement. He showed pictures of the failed gasket (part is 10 years old - out of warrenty). I will request to have him for future visits

John and Gerardo did a fantastic job installing our hot water heater. They took their time to ensure my questions were answered and the job was done right. Highly recommend!

Harris is outstanding and I always ask for him. He services 2 of my furnaces and another furnace for the condominium association. He is detailed and very efficient. He gives me tips on how to maintain the units. He is very respectful and loves my dog.

Another very nice appointment with Miguel Herrera, and Ryan. On time, efficient, friendly. Services to consider for UV lights and water heater flush were discussed without hard sell. This was a winter heating check. Renewed my annual service contract, $240, so no additional needs at this appointment. All neat and clean when they left, about 45 mins total. Ask for Miguel!

Dan Gerardo and Johnny did a great job installing new system. Tough install in attic and they did great. Cleaned up well after also. Worked late to get it done.

Today Ron Bebee came to service our water heater. Ron was very professional and extremely efficient with his work! Our water heater is in a crawl space and did an excellent job with this situation! I would highly recommend Ron and Comfort Master Service Experts!

Always great service from Comfort Masters and especially Spencer! He solved our problem promptly…explained everything thoroughly…and kept us well informed throughout the repair process. Very professional and highly recommended!

Excellent Diagnostic Service 99.00. Very reasonable. Roy came out on Sunday morning. My disable brother’s Furance was acting up and a repair was needed. I await a call on Monday Dec1,2025. To see if I can afforded the repair. Thank you Golden Seals.

I wanted to update my prior review, which didn’t do justice for the service I received. I was in a real pickle. The night before I was about to leave on a long RV trip (Chicago to California), I used my outdoor spigot to put some fresh water in my motorhome. I wasn’t able to shut the water off at the spigot - the valve stem in the spigot was damaged. I had to use the main shut off valve for the whole house - we had no running water and my wife needed to have running water while I was gone. Fortunately, I was able to go online and schedule a Comfort Masters plumber to come to house the next morning. Obviously, the spigot needed to be replaced, but it was an unusual size and not immediately available. The Service Master plumber recognized my situation and was able to quickly solve my problem by installing an emergency shut off valve on the water line leading to that spigot. It took him very little time and I was able to hit the road much sooner than I believed possible. Thank you Service Masters!

Haris is one of a kind, probably the best technician to have worked on the house. He was extremely knowledgeable and honest. Went above and beyond with not only resolving the issues but helping me learn some of the ins and outs so I can understand the situation better. Will only be asking for Haris moving forward. Highly recommend him.

My new Lennox gas furnace was installed today by Gerardo and Dan. I am very satisfied with their outstanding job. It is highly comendable. Dan explained to me everything that I needed to know about the new Lennox gas furnace, new Honeywell thermostat, the new April Aire humidifier and APCO-X ULTRA Air Treatment System.
I will highly recommend them to friends.
Thank you very much Gerardo and Dan.

Haris did an amazing job fixing our humidifier that runs with the furnace. He took time to explain the problem. He also took time to explain how to prevent further issues, along with ways to maintain the attached water pump. Thank you so much!!

Haris came out to do our annual furnace inspection. He was very thorough and pointed out what parts we want to have replaced next year. He also gave many tips on things I can do to keep our furnace, humidifier and water heater running for many years to come.

Dan explained clearly what he was doing and how failure would affect our HVAC system. I hope he is available and can be assigned for our spring a/c system evaluation and maintenance. We have been loyal customers since they installed the system, ten years ago.

We used Comfort Masters to install a new in-line humidifier and Air Filter/UV system. The old system was incorrectly installed and not functioning. Haris removed the old system and installed the new one. He did a very professional job. What an improvement. We will be having a tankless water heater installed in a few months, we will definitely ask that Haris to do the installation and all future maintenance checks. Great service.

Spencer did an outstanding job replacing our sump pump. The work was completed quickly and professionally, and they left the area spotless. Highly recommend.

A great experience from start to finish. We appreciated the prompt scheduling and the plumber's commitment to ensuring the installation was done right the first time.

It's always good to have Roy check our systems, whether it's our furnace or a/c. He found that our ignitor needed replacing at this inspection and did it in only 20 minutes. He is thorough, efficient and nice! We've had the Comfort Masters system and service since 2017, bought via Costco.

Had our heating system replaced. Dan and John did the unit replacement and they were great. Explained what they were doing and told us the time frame it would be done which they followed. New heating unit works great. Will definitely recommend to friends and family

Arrived on time on a snowy day. Showed respect for our home and got right to work. It was just a furnace inspection but the tech was friendly and professional. He answered all my questions and was in and out promptly. I have been using Golden Seal for years and have never had an issue with their work.

We purchased a high-end HVAC system 14 years ago and have been incredibly pleased with the performance of the system. We also signed up for the maintenance contract to protect our investment. For the first 10 to 12 years, we were very pleased with the service. That said, in the last couple of years something has changed and not for the better. First of all, the scheduled service dates have been cancelled in several instances. Not sure if they are having employment issues but when you arrange your schedule to be available for the appointment and then it gets cancelled is disappointing to say the least. More alarming, is what I perceive to be a new approach to increase their business/profits. Last year when they came out for the spring A/C maintenance check we were informed that our unit needed a new capacitor, cost was over $400. I checked the part on line and it was about $45. I would have been happy to have them do the work but not at a 10 fold price premium. More recently we had our winter furnace inspection and once again presented with a part that needed to be replaced. The repair requirement appeared to be legitimate but was going to cost $1,700 plus. Once again, I checked the part on line and it was roughly $275. These are outrageous markups! If they really want to keep me as a customer going forward, they need to reassess there pricing policy for repair and maintenance.

Joshua Smith was our technician today. My husband was impressed with the service provided today. Joshua did a thorough inspection, patient, knowledgeable and provided additional information regarding troubleshooting if necessary. This is the first time he experience this type of service with a serviceman. Kudos to you, Joshua.
The maintenance service (2 visits per year) was included with the purchase of the system.
