The Allentown18109 calls we answer most often
If your system is doing any of the following, it is worth a diagnostic before the fault gets more expensive.
Heat pump stuck blowing cold air in heating mode

Skyrocketing utility bills with no change in usage
Thermostat reading several degrees off from reality
Loud banging on start-up (compressor slugging)
Breaker trips every time the system starts
Heating and air conditioning service built around Allentown
If your gas and oil furnaces with central air has started short cycling, blowing warm air or making a noise it never used to make, you are not alone — Allentown generates some of the highest call volume we handle in Pennsylvania. Cold winters in the west and humid summers statewide, with lots of older systems due for replacement.
Homes in Lehigh County tend to be a mix of older builds with original ductwork and newer infill construction, which means airflow problems show up very differently from one street to the next.
Peak cooling demand here runs June through August. Booking a tune-up in early spring means you are not competing with the whole neighbourhood for a tech in July.

Allentown18109 HVAC questions, answered
How quickly can a technician get to Allentown?
For the 18109 service area our target response time is 2-4 hours from the moment dispatch confirms your address. Real-world timing depends on the day — the first sustained heat or cold snap of the season is always our busiest period — but we hold technicians locally specifically so that window is achievable rather than aspirational.
Should I repair my system or replace it?
The usual rule of thumb: if the repair costs more than half the price of a replacement and the equipment is over ten years old, replacement generally wins. We will run that comparison with you on site and show you the maths — and if the honest answer is a $180 capacitor rather than a $9,000 system, that is the answer you get.
Can you give me a price over the phone?
We can give you realistic ranges — and this page lists the ones homeowners in Allentown see most often — but a firm price needs eyes on the equipment. Any company that quotes a final number without seeing the unit is usually quoting low to get through the door.
What brands do you service in Allentown?
All of them. Our 18109 technicians are trained on Rheem, American Standard, Carrier, Heil and essentially every other residential brand sold in Pennsylvania, including discontinued lines. We keep a broad parts catalogue on the trucks for exactly that reason.
Do you charge extra for nights, weekends or holidays?
No. Our pricing in Pennsylvania is the same at 2am on a holiday as it is at 2pm on a Tuesday. Emergency calls are dispatched the same way as scheduled calls and carry no overtime premium.
Is my carbon monoxide risk something I should worry about?
With any combustion appliance, yes. A cracked heat exchanger can spill carbon monoxide into the living space, and it is odourless. We perform combustion analysis and a CO test on every furnace and boiler call in Allentown, and we recommend a working CO alarm on every level of the home regardless of who services your equipment.
