Excellent job...was competent and very pleasant to deal with ...thanks Jordan
They came out the same day we called. Initially, we were only looking to repair our AC unit, but after learning more about the condition and age of our system, we decided to replace both the AC unit and furnace. At 23 years old, our existing systems had definitely served their time. What really stood out was the…
I had a problem with my air conditioner unit and Comfort Zone came out that day to assess the situation. Josh, the service technician was great. He explained everything he was doing and gave me a few options to remedy the situation. UPDATE: The compressor on my AC unit was shot and since my HVAC system was 18 years…
Comfort Zone came out quickly when our heat stopped working right before Christmas. They were able to get a new furnace & air conditioner installed for us the next day. Every person that we've talked to or had at our house is so friendly and accommodating! They came out today to get the air conditioner finished…
Dave and Tim did a great job! They were very professional, friendly, and helpful. They were neat and efficient in the installation of our dual AC/Furnace units. I would definitely recommend Comfort Zone and use them again.
So glad I went with Comfort Zone for new Furnace/AC. They are not only professional but also exceptional! The estimate I received from Chad was clear and concise and pricing fair for the products I chose. The ladies in the office were pleasant and easy to deal with setting up my appointments and offered honest and…
So glad I called Comfort Zone to replace my old A/C. From the initial consult, to the follow up and install, they were professional, knowledgeable, and super efficient. They offered several options, and the price was right. They notified me when they were on their way, provided a picture and listed the experience of…
Always great service, very fast and easy appt schedule, always on time , always good energy. Been using their service for over 2 years now. Keep up a good work! Thank you, Comfort zone team!
Brenden and Marco installed a new high efficiency Carrier furnace, Aprilaire Humidifier and a Respicaire Air Sanitizer. The dual stage furnace, Aprilaire with its own blower and the Air Sanitizer work perfectly. A beautiful installation. Top quality professionals. Comfort Zone has been our HVAC EXPERTS for several years. Emil and Jill thank you!
Technicians took pride in their work. They were clean and thorough providing answers to every question along with recommendations for maintenance. They also cleaned up past poor duck work configurations. Always satisfied with comfort zone.
I had a very good experience with Comfort Zone as did my mother-in-law and one of her friends who recommended the company. Brendan did an excellent job on my installation. He was friendly, very knowledgeable and very good about explaining things to me. The same is true of Jamie in the office who was always friendly…
Comfort Zone has been great to deal with. They have been my go to HVAC company since 2017. I regularly have them service my HVAC units every year and just recently had them install AC for my second floor. Very happy with their service would recommend them to anyone.
From start with requesting a quote for a/c and heat system, Jamie answers the phone and take information that is so professional yet extremely friendly, she is an asset to Comfort Zone and I have to say that all the staff that I dealt with were awesome. Jim was friendly and helpful when he came to look at old a/c…
