HVAC reviews in Glendora, California

As always, Jim was on time, courteous, and professional. The problem was repaired and explained. The office personnel were prompt and efficient in their follow up and kept me posted of technician’s ETA. Comfort Zone has my highest regard for their services, technical and customer.

We chose Comfort Zone to install a new Trane heating and AC unit for our home. They were a pleasure to work with. Steve and his team are so clean, organized, punctual and professional. They were respectful of our home and our time. They worked neatly by covering the floors they walked on, picking up all the trash & extra parts each day before they left. They installed with care, as if it were going into their own home. The work was very neat. My husband is a perfectionist and Comfort Zone did not disappoint! They responded quickly to questions we had after install as well. Overall, it was a great experience for a high end purchase! We highly recommend giving them a call.
The unit itself, is so quiet and efficient we love it.
Thank you Comfort Zone!

Steve is our go to guy when our A/C is in need or repair. Of course, it seems to go out during the heat when he is getting lots of calls but he was here with a smile the day after I called. Excellent service!! There are’t enough stars to properly rate him.

Steve and his team are the best. They always have high quality standards, professionalism, respectable, knowledgeable and very friendly. We never have any problems with their work. Outstanding service!

Jim was everything you’d hope for in a service call. Prompt, friendly, knowledgeable, genial, and willing to take time to help me understand the complications with my home system. Even showed kindness toward our dog and cat. Little connections like that make a big difference. Love to have him back.

They always take great care of our system and our needs.

They are always on time, professional, get the job done, and extremely reasonable on price. Trustworthy and experienced so you know you’ll get great service. Raymond went out of his way to help us.

Very happy with the work! The guys were great and very professional. Will definitely recommend them to family and friends. Comfort Zone will be our new go-to for all our heating and ac needs.

Jim was friendly and efficient. He explained the process and shared details of his findings. He went to work and cleaned, repaired, and checked my HVAC system thoroughly. Excellent experience!

Jim came out and evaluated our AC system which just recently started to trip the breaker this past week. His diagnosis of us needing a new breaker fixed the problem! Very appreciative and grateful for his expertise and explanation of this situation as he worked through it.

From our first phone interactions with everyone in the office we were impressed with Comfort Zone folks' great communication - prompt and knowledgeable and friendly. Even though we had furnace venting needs, they were able to get us on their schedule during this very busy AC season. And then we're so grateful to have met Steve who was so knowledgeable and has so much experience, we felt our 100-year old house was in great hands. His experience and integrity filled us with confidence. We're so happy that Comfort Zone did our work!

As always Steve and his crew are right on time with the best service. Today Jim came to our rescue with a broken a/c repair. They are all fast and efficient clean and friendly and their prices are always fair. Oh and when you call the office you talk to real people that know how to communicate. What a great business! Thank you Comfort Zone!

Jim was awesome. Came in and fixed our cooling issue within 20 minutes. 100% recommend Comfort Zone, Inc for HVAC issues, and if you get Jim as your guy, that's just a bonus!

Awesome service starting with Ashley with the booking process & Steve was very knowledgeable and got the job done! Very professional. Thank you!

We first learned of comfort zone when we remodeled our kitchen. We called them back when we found a small leak in our furnace. Both experiences were great. Steve is very knowledgable.
Update: Just had our annual service on the HVAC. Raymond did a great job. I continue to recommend Comfort Zone.

Steve was an amazing technician. Trouble shot everything perfectly. Once he figured out what was wrong, the solution and turnaround time was very fast. Highly recommend these folks!

Ray, the technician from Comfort Zone provided exceptional service. He thoroughly analyzed the situation and made the necessary repairs in a timely manner. Comfort Zone is truly the best!

Great reputable service that is highly efficient with their work. Raymond is courteous and honest and gave me honest assessment and solution to my heating unit issues. I couldn't be happier with the team's work, from getting the appointment set up, to coming out to resolve my heating issues so quickly - within 24 hours. I would highly recommend comfort zone and specifically Raymond for the service provided.

Great communication. Had to have my fan motor replaced. Steve, Jim and Ray all great guys. Been using Comfort Zone for many years for my annual maintenance. Fast and friendly service.

Excellent customer service! Very thorough servicing of our two HVAC units. Highly recommend Jim. Thank you.

The Comfort Zone technician, Ray, was polite and helpful. He made sure we were satisfied and offered advice for future troubleshooting. For over 5 years, anytime we need service for our heating/cooling system, we always use Comfort Zone!
