What Our Customers Are Saying About Our Heating and Air Conditioning Services

Don’t just take it from us, let our customers do the talking!

“Your technician was outstanding! A true asset to any company, but especially yours. In addition the phone service rep tried to troubleshoot me on the phone in order to save a service call.”
Charles W.

“In the 10 yrs as a customer I have been treated with the utmost respect. I find your telephone people very knowledgeable and your technicians not only know their job but are fun to talk to.”

You guys are great. Thanks for fast service at my time of need. Had no heat, called 7AM and my heat was on by 3PM. Thank you so much.”
David S.

Bear, DE

“We recently purchased a complete Lennox HVAC replacement system from your company, and our experience with representatives on your behalf was excellent.

Mike Shallcross, your HVAC Specialist, was very thorough in helping us select a replacement furnace and A/C unit that completely met our needs; and, he did so in a professional and informative session that resulted in a very balanced system. Moreover, the new system solved a series of air flow bottlenecks in our 23 year old unbalanced and under sized units. Mike also followed up the day after installation to insure everything met our expectations.

The other important half of a great performing Lennox HVAC solution is the installation itself, and your lead technician (Joe) and his assistant (Justin) were outstanding. The quality of their workmanship was superior, and the result is a customized install based on their knowledge and skill that should bring us comfort for many years to come.

I took the opportunity to share your company’s performance on the Lennox website, to the best of my ability, and plan to refer your service to friends and family. As a 23 year customer of SchagrinGas Company, we look forward to many years of great HVAC support, from a reliable and professional support team.

Thank you.”
