After reviewing furnace and ac bids from seven local heating and air conditioning contractors in terms of the quality and energy efficiency of the units being sold, the professional experience of the installers, the warranty offered, and the overall cost, we chose Komfort Keepers. We could not be more satisfied. They followed up after installation to make sure everything was just right for us, and I am sure that Komfort Keepers will offer us first-rate service for years to come. I just asked them to work up a proposal for a new gas hot water heater.
