HVAC reviews in Glendora, California

Steve was super. A/C is essential with my medical condition. Steve arrived early, identified the problem, explained it in a way I could understand and worked out a plan to not only get me comfortable but to verify that the entire issue was resolved. He went above and beyond and I am ever so grateful.

Been with Steve and Comfort Zone since we bought our house. The only AC company we’ll use. 5-stars all the time!

We highly recommend Comfort Zone! Steve Lucey and his crew were professional, highly skilled, and respectful of our home.

Jim’s phenomenal. I’ve been a loyal customer for over 30 years. The service and attention to detail is unmatched.

Great service from Raymond Joyal. Fast, efficient, affordable and easy to deal with. Will certainly use them again .

Ray and the entire team at Comfort Zone are the best. We feel fortunate to have had them install/maintain/support our home's HVAC systems all these years

Jim called me ahead of time to let me know he was coming! He is so personable he’s great! He did a detailed job on the unit cleaned it up good inside and outside! He’s a great guy!😁

Arrived at the set time. Fixed the problem. Inform me of the right filter size, and was very neat. Inform me about preventive maintain the air/heating system.
Very Good experience. Would recommend this company.

Technician was on time. Friendly and efficient. Comfort Zone has always been super organized and has great communication with their customers.

Called the office of comfort zone and was quickly able to get on the schedule. They sent out Jim to do a maintenance on my heater and my AC and everything was great. Can’t wait to use them again for my summer maintenance.

We’re so glad we chose Comfort Zone! Our technician, Raymond, was extremely knowledgeable and professional. He quickly diagnosed the issue with our blower motor and arranged for a replacement part. Just two days later, he returned and had everything fixed quickly and efficiently. We also worked with Ashley regarding the warranty, pricing, and scheduling—she was incredibly organized and made the entire process smooth and stress-free. The pricing was very reasonable, and unlike other companies we’ve tried, there was no pressure to buy extra services or deal with hidden charges. Comfort Zone has truly earned our trust, and they’ll be our go-to AC company from now on!

Jim Heflin from Comfort Zone, Inc. provided excellent service. He was professional, knowledgeable, and took the time to explain everything clearly. The work was completed efficiently and the pricing was fair. I appreciated his attention to detail and courteous manner throughout the visit. Highly recommend Comfort Zone and will definitely use them again for future HVAC needs.

Our AC was short cycling constantly. They diagnosed the issue and replaced a worn component. The system now runs smoothly and efficiently.

Old system kept shutting off their crew inspected the HVAC system and got it running like new again.

The AC wasn’t cooling at all this week. I scheduled A/C repair and the technician replaced a worn capacitor. The house feels cool again in no time.

My system wasn’t responding to schedule changes. Their technician updated the thermostat programming and synced it correctly. Now it follows the schedule perfectly.

I scheduled a pre summer HVAC inspection. The technician checked coils, filters and refrigerant levels. Everything is ready for the heat.

The outdoor condenser was very noisy. They tightened loose panels and lubricated parts. The noise reduced significantly. Excellent repair work.

Our AC suddenly stopped working during a hot day. Their team arrived fast, diagnosed the issue and replaced a worn out part. The house cooled down quickly. Very professional and efficient.

What’s their number? The one on their profile is disconnected

Very affordable prices and great customer service!
Brian and Armando are veer knowledgeable and have a lot of experience.
