“I had Kevin work me into his schedule on one of the hottest days during a brutal heat streak. He was quick, respectful, and fixed my problem within 2 hours of my initial phone call. The office staff was also very nice, polite, and extremely helpful.”

“This place is worth all of the good reviews. We had an issue with our unit, that wasn't the fault of Bethany Air, and Bethany Air went above and beyond to fix it. Everyone was friendly, compassionate, and helpful. I have a lot of trust and faith in them after working with them.”

“A truly great experience. I called and was able to get a technician the same day. The call manager was extremely kind and helpful, checking every option despite being completely booked and found me a tech in my area.”

“A very good morning with our service technician: on time, fast, friendly and no surprises. I had a technician in my home within 24 hours with excellent results. We had a check of the system units and also made the vibrations in the outside unit go away.”

The reason to do this before the first cold night is simple: a furnace that has sat idle since March will show its problems on the night you need it, and that is the worst night to find a technician.
What Gets Checked
The heat exchanger inspected: the component that separates combustion gases from the air you breathe. This is the safety check that matters most.
Combustion and venting verified: that the furnace is burning cleanly and that everything it produces is leaving the building.
Safety controls tested: limit switches and the flame sensor, which are what shut it down before a fault becomes dangerous.
Airflow and filter checked: restricted airflow is the most common cause of a furnace overheating and short cycling.
