When our 22 year old heat pump finally decided to quit we had no doubt who to call to replace it. Glendale Heating has serviced it for all those years very well. Sales consultant Debra went over multiple Lennox heat pump options with us. She always responded to our inquiries very promptly even after hours and was very pleasant and knowledgeable.

The communication with her was an absolute breeze. The installers Brian and Zeke were also awesome. They worked very efficiently and their knowledge about installed equipment was evident and undoubted. Our house is very unique and the placement of indoor and outdoor unit is not typical or usual.

They had to overcome multiple challenges that included limited space for new indoor unit and bringing new line set and electric supply into the house due to limited access. They handled everything with the utmost confidence and kept us informed about the installation progress or possible modifications. Yuri completed work, fired the system off and showed us how to use Nest smart thermostat. The entire Glendale Heating team and everybody who participated in our heat pump replacement project was very courteous, honest and professional.

Our new heat pump is super quiet and very efficient. The air quality in the house has improved tremendously and we have noticed it within two days. We now regret that we did not listen to Glendale Heating when they suggested we should start thinking about replacing it several years ago. We are confident that our new heat pump will serve us well for many years to come. Perhaps for another 22 years. Kudos to Glendale Heating for their excellent work ethics.

Response from business owner

Ajitha, I really appreciate your review but you might have us mixed up with another company. We work on home comfort equipment, but don't do air duct cleaning. I hope the work we did for you also met your high standards and we look forward to hearing from you again.

Workers were efficient installing A/C and left nothing to clean up. When there was a problem initially with the A/C they were prompt in fixing the problem. Thank you!!!
