Called another company for a second opinion, didn't tell them anything about my All Temp quote, $250 including labor to replace the board and a new furnace, same energy efficiency and BTUs $2300. When I then showed him All Temp's quote, he was amazed that they could even live with themselves, trying to overcharge me because I didn't know any better. Sad and disappointing.

The tech fixed the issue and then charged OVER $800 PLUS SERVICE CALL TO REPLACE A $35 PART. $35 was the OEM cost through the company site. When Mr. RITTER was confronted he threatened to sue me while demanding he come take the furnace apart immediately on a Friday night costing me yet again another after hours service call from another company vs returning my call right away during business hours earlier in the week. Avoid at all costs.

Staff on the phone has always been personable, prompt, and courteous. Mason's is a top-notch outfit, the likes of which you just don't see much anymore these days. They replaced the A-coil and outdoor condenser unit for our non-working central air, and they did it for substantially less than any other estimate from the well-know big brand names in town. Mason's was highly recommended to me by a co-worker, and I have no problem doing the same. Call Mason's before you decide to go with any other HVAC business, and I bet you won't regret it.
