Great technicians




Sergio and Tony took the time to diagnose and did a great job fixing my heating system. I highly recommend Great Lakes!


Response from Great Lakes Heating, Air Conditioning & Electrical:

Thank you for the feedback! We are anxious to get Tony P out on his own, he is a fine man with a lot of talent. It is good for us to hear positive feedback on him and on Sergio. Mike

Very happy with great service, and great service technician




Sergio came for a routine air conditioning checkup, and ended up locating and fixing a gas leak for us. He was polite, professional, and obviously knew what he was doing. We also found him to be careful, methodical, and thorough--- everyone's ideal of a great service technician! We were also delighted he could repair the leak on that same visit, and that we didn't have to reschedule another service call. We have been with Great Lakes for years, have always been satisfied with the good service, products, and pricing, and continue to recommend Great Lakes to friends and family.

Excellent! Found flaw which had caused problem for years.




For years, our zones had not responded to thermostat settings. It always got too hot and dry for my musical instruments, in spite of setting as low as 66 F. Mr. Sergio Jesus Quijada, the service rep from Great Lakes, figured out that 3 of 4 valves were not functioning. He also instructed us to always set the thermostat for "auto" rather than "on" because "on " will result in everything being wide open and too much hot air coming through. As for the number of stars for rating, I give 5 for quality of service, but have nothing to compare the cost to or the convenience, so I don't really know what to say. I gave 5 stars for the latter two anyway, because I gave 5 for the service person.


Response from Great Lakes Heating, Air Conditioning & Electrical:

These 5 star reviews are music to our ears! Thank you for a great review!
