I had a problem with my 20 -/+ year old furnace igniting reliably. I’m pretty handy (farming/technical background) but didn’t want to screw anything up, plus it was a good opportunity for inspection (per carbon monoxide poisoning). After reading reviews of Prescription Heating & Cooling, I was confident enough to give them a shot. Mike (the owner) definitely lived up to the reviews: I left a voicemail with him & he returned my call within 10 minutes and made appointment for that same day. Mike was right on time & opened up my furnace within 90 seconds of arrival. He also inspected the heat exchanger for carbon monoxide poisoning without being asked. Mike diagnosed problems and gave me the option to fix it myself or have him do the with a 30 minute price quote. I elected to fix the problem myself & he had no problem with that. He gave a boat-load of free advice on looking down the road at replacements without the assumption of him being the only one to work with. He still applied a discount coupon, but his service was so great I gave him more. I really value information & relationships like Prescription Heating & Cooling provides.
