the crew came for a seasonal furnace tuneup and they was very polite. the technician check the burners, clean the flame sensor, and test all the saftey controls. he explain what he find and answer every question we had. the furnace start easier now and it dont make the same clicking noise. they also leave the basement cleaner then before, and the final cost were exactly what we was told.

Our furnace stopped working during a cold morning, and Air Conditioning & Heating Repair arranged service sooner than expected. The technician diagnosed a faulty flame sensor, explained the repair clearly, and provided the total price before beginning. He had the correct part and restored the heat during the same visit. He also tested the safety controls and thermostat before leaving. The response, preparation, and workmanship were outstanding, and every part of the service felt professionally handled.

the technicians arrived within the scheduled window and completed a thorough air conditioning tune-up. they checked the condenser, electrical connections, thermostat settings, air filter, and airflow at several vents. the technician explained what was in good condition and pointed out one component that may need attention in the future. there was no pressure to replace anything early. the service area was left clean, the invoice matched the quoted price, and the AC has been running smoothly since the appointment.

Do not call anyone else! These guys are the best. They installed our AC and were honest, reliable, and provided the best equipment at the best prices. And no slimey sales tactics. When our furnace blows we will for sure call Welters. Also they left a little gift basket after completing the install, which was just SO classy. Very solid company, thank you!
