Total replacement of 2 high efficiency furnaces and AC units, ductwork, removal of rock wool insulation and replacement with r60 at our request. David was great to work with on our redesign and upgrades of our HVAC. He spent all the time I asked to make sure we would get what we wanted out of the project. We ended up rezoning the AC units and added appropriate returns and supply to make sure everything would work as expected. HVAC crews were some of the most professional and cleanest I have ever dealt. They were thorough in their work and even impressed the city inspector. They were able to complete all the work in a few days and made sure we were not without climate control. They were respectful of our home and made sure we were all right with any site changes to the plan. Everything about them screams professional. We now have two top tier Dave Lennox systems that provide a 3-5 mile per hour breeze through out home at all times. Even with running the fan more, we are seeing a 30-35% energy savings in summer and winter so far. The house smells so fresh and is so comfortable. The insulation team did a fantastic job of removing the old rock wool and then when the time came for the new insulation were able to get the 3100 square foot house completed in a single day. Absolutely no mess anywhere in the house. I cannot recommend EHS and David’s teams enough. I will let them work on my other home when the time comes. They are a great locally owned business that cares about their customers and the results of the work they do. Call them today, say Hi to Jill (one of the greatest office managers on the planet), get your systems, get your insulation, and be comfortable. PS. I am not related to this company other than they did great work for me and they will for you too.
