Alanne installed my HVAC systems in my new 2 story home. Jeff was very professional as were his employees. The furnace and air-conditioner I have been working great for two years now, I would highly recommend this contractor. When my kids broke a plastic elbow to the condensate drain, Jeff was quick to respond. During construction I made some changes to the location of the LP range, and they accommodated my last-minute changes.I also like the warranty that comes with the furnace. Would use this contractor again.
