     “In the past several weeks, when the weather started warming up again, the thermostat was switched to "auto" and nothing happened. You could hear buzzing inside the AC unit, yet it never came on. We called a local company , but were shocked when the diagnosis came back that our 20 year old system had a bad compressor(even though the compressor had been replaced in 08). The technician told us that when he went to put freon in it, it just leaked right out of the compressor head. We were pretty shocked when we were sent a quote of $3300 for a new compressor and about $11000 for a new system (ground source heat pump). So we asked Luke Welker of Welker Heating, Cooling, Plumbing to take a look before we took the expensive plunge. Guess what? The compressor was fine; there was a leak in the thermal expansion valve. Luke fixed it, re-charged the system and it has been working fine ever since. He was able to correctly diagnose the problem that had been misidentified by a technician with many years of experience. You can probably guess who will work on our system from now on, and install the new system when the time comes. Welker Heating, Cooling, Plumbing just saved us a HUGE!!!!! chunk of money. ​Honest, competent, fair, and dependable, you can feel good when the job is completed because you know you have been served well."​
