Gas, propane and oil furnaces. Owner-run, based in Macungie, answered 24/7.
When a furnace quits in a Lehigh Valley winter, you want someone who answers the phone and knows what they are looking at. I’m Tyler Furbacher. Unity Heating & Air Conditioning is my company, I run it out of Macungie, and I do the furnace repairs myself: natural gas, propane and oil furnaces, standard and high-efficiency, in Allentown, Emmaus, Whitehall, Breinigsville, Trexlertown and across the Lehigh Valley.
A good repair starts with finding the actual fault, not swapping parts until the heat comes back. On a no-heat call I track down what failed, check the safety controls, flame and venting, and tell you what the repair costs and whether the furnace is worth fixing before any work starts.
No heat right now? Call or text (267) 644-9516. Emergency calls are answered around the clock.
Furnace problems I fix
Most no-heat calls come down to a short list of parts. These are the ones I see most in Lehigh Valley homes:
Furnace running but blowing cold air
Igniter, flame sensor and gas valve faults
Blower motors and capacitors
Control boards and limit switches
Draft inducer and pressure switch faults
Clogged condensate drains on high-efficiency furnaces
Oil burner nozzles, filters, pumps and electrodes
Thermostats and low-voltage wiring
How a furnace repair visit works
You talk to me, not a call center. On the phone I ask a few questions (is the blower running, any blinking lights, gas, propane or oil, roughly how old the furnace is) so I show up ready for the likely fault.
On the visit:
Find the fault with meters and a combustion analyzer instead of guesswork
Check the safety controls, flame, venting and filter
Explain what failed and what the repair costs before any work
Make the repair, then run the furnace through full heating cycles to make sure it holds
Tell you plainly if the furnace is near the end, with the numbers to decide

Quick checks before you call
Every winter a few no-heat calls turn out to be something you can fix in two minutes. Try these first. If none of them brings the heat back, call.
Safe things to check:
Thermostat
Set to Heat and a few degrees above room temperature, with fresh batteries if it uses them.
Furnace switch and breaker
The switch on or near the furnace (it looks like a light switch) is on, and the furnace breaker hasn’t tripped.
Filter
A clogged filter can make a furnace overheat and shut itself off. If it’s gray, change it.
Blower door
The panel over the blower has a safety switch. If the door isn’t seated, the furnace won’t run.
Oil or propane level
Check the tank gauge. An oil furnace that ran out usually needs the line bled before it will restart; press the oil burner reset button once at most.
Condensate drain
On a high-efficiency furnace, a clogged drain or a full condensate pump will shut the furnace down.
Smell gas, or a carbon monoxide alarm going off? Don’t troubleshoot. Get everyone out of the house, call 911 or your gas utility from outside, then call me.
Repair or replace?
Most furnaces I see are worth repairing. A failed igniter, flame sensor, blower motor or control board on a furnace under about 15 years old is a repair. It tips toward replacement when:
The heat exchanger is cracked. That is a carbon monoxide risk, and replacing the heat exchanger costs a large share of a new furnace.
It’s the second major repair on a 15 to 20 year old furnace. At that age the next failure usually isn’t far behind.
An oil furnace can’t pass a combustion test after cleaning and adjustment.
Do you repair oil furnaces as well as gas and propane?
Yes. I work on natural gas, propane and No. 2 heating oil furnaces, including high-efficiency condensing furnaces, and on most brands found in Lehigh Valley homes.
Can you come today?
Emergency calls are answered 24/7. Call or text (267) 644-9516 and you’ll get an honest arrival time on the phone.
Why is my furnace blowing cold air?
Usually the burners aren’t lighting or keep shutting off: a dirty flame sensor, a failed igniter, an overheating shutdown from a clogged filter, or on high-efficiency furnaces a blocked condensate drain or vent. On oil furnaces it’s often an empty tank, a clogged filter or nozzle, or a burner that has locked out.
Why does my furnace turn on and off every few minutes?
That’s called short cycling. Common causes are a dirty flame sensor, overheating from a clogged filter or closed vents, a furnace that is oversized for the house, or a thermostat problem. It wears the furnace out faster, so it’s worth fixing.
Should I repair or replace a 20-year-old furnace?
If the repair is small and the heat exchanger checks out, a repair can buy you a few more winters. If the repair is major or the heat exchanger is cracked, replacement is usually the better use of the money. I’ll tell you which, with the numbers.
Which towns do you cover for furnace repair?
Macungie, Alburtis, Emmaus, Allentown, Whitehall, Bethlehem, Easton, Breinigsville, Trexlertown, Wescosville, Fogelsville, Ancient Oaks, Upper and Lower Macungie, Coopersburg, Center Valley and Quakertown.
