Two systems do most of the work in a typical home, and they're the two we repair most. Here's what to expect when you call.
A dead air conditioner on a hot afternoon is the call we run most. The usual culprit is a small electrical part, a capacitor or contactor, that our trucks carry, so most AC repairs are finished in one visit. Every repair comes with an upfront quote and an honest opinion on repair versus replacement.
Most furnace breakdowns come from a handful of parts: flame sensors, igniters, inducer motors, and control boards. We find the one that failed and fix it, usually in a single visit. You'll get a clear quote first, plus a safety check of the combustion and venting while we're there.
HVAC trouble can appear without warning. If you're seeing any of these problems, don't wait to call for fast, professional help.
A system pushing warm air in summer is the call we run most. Our trucks carry capacitors, contactors, and motors to restore cooling same-day.
AC repairFrequent on-off cycling is the furnace protecting itself from a real problem. Ignoring it risks the heat exchanger, the most expensive part in the cabinet.
Furnace repairEnergy bills creeping up while comfort drops means the system is working harder than it should, dirty coils, clogged filters, or failing motors are the usual suspects.
Maintenance & tune-upsWe size replacements with a real load calculation, not a guess, so the new system delivers even temperatures and lower bills from day one.
System replacementDust settling everywhere within a day of cleaning, musty odors when the system kicks on, or allergy flare-ups indoors all point to the ductwork.
Air duct cleaningAdditions and bonus rooms rarely get enough duct capacity. A dedicated ductless head fixes the problem permanently.
Mini-split installationMost repair calls are diagnosed and fixed in a single visit because we stock the common parts, capacitors, contactors, igniters, motors, on every truck.
The person at your door knows HVAC inside and out, from superheat readings to error codes, because we hire seasoned pros and keep them sharp on the methods that actually work.
You'll get a clear written quote before any work starts, and the price you approve is the price you pay. That's why so many customers call us back.
Installations get the full treatment, real load calculation, correct line sets, sealed and balanced ductwork connections, and a complete commissioning test before we leave.
For over 12 years, Allentown HVAC has been the trusted name for HVAC service in this part of PA. Our locally based technicians know the specific conditions that local comfort systems face, from the age of local housing stock and its ductwork quirks to coastal air that corrodes condenser coils.
Anyone can bolt in a condenser. Lasting comfort comes from understanding the home and the system together, and that's where our years working in this area pay off, fewer callbacks, faster fixes, and installs that pass inspection without drama.
Talk to someone who actually knows heating and cooling. Honest, no-pressure pricing over the phone.
From the first call to the final airflow check, our method is built to solve the problem completely the first time.
Ring (610) 753-9199 whenever it suits you. We'll talk through the symptoms, tell you if anything needs immediate attention, and lock in a visit time that fits your schedule.
Our technician tests the system, capacitors, motors, refrigerant charge, ignition, airflow, safeties, pinpoints the actual fault, and presents your options with clear, upfront pricing.
Most repairs finish the same visit, our trucks carry the common parts. Replacements are installed to code with proper sizing, sealed connections, and clean workmanship.
To keep your comfort reliable long-term, we can set up seasonal maintenance that cleans coils, checks the charge, and catches small issues before they strand you in the wrong season.

Speed matters when the temperature is climbing or dropping. This is the sequence our team runs through, from the moment your call comes in to the moment your system is running again.
When you call (610) 753-9199, you reach our local team directly. We listen to what's going on, note the details that matter, and get you on the books, often within hours, with quick guidance on what to do until we arrive.
Your technician shows up ready to work, not just to look. The common failure parts ride on every truck, so the visit moves straight from diagnosis into repair.
The technician confirms exactly what failed and why, then fixes it on the spot, and if the system is beyond saving, walks you through right-sized replacement options with real numbers and a realistic timeline.
We verify the fix held and answer any questions after the visit. For older systems we set up seasonal tune-ups to extend the system's life, which is the cheapest comfort insurance there is.
"The furnace kept short-cycling, kicking on and off every few minutes and never really warming the house. The technician found a clogged filter had tripped the limit switch and cleaned the flame sensor while he was in there. It runs like new now, and he showed me which filter to buy going forward."
"When our old furnace was on its last legs, they walked us through converting to a heat pump instead of just quoting a like-for-like swap. Our winter bills dropped noticeably the first season, and we got cooling out of the same equipment. Best decision we made on this house."
"We put a ductless mini-split in the bonus room over the garage that was always freezing in winter and roasting in summer. They measured and calculated instead of eyeballing it, and the install was clean and quick. That room is finally usable year-round."
Good HVAC service comes down to doing the small things right. These are the commitments that earn Allentown HVAC repeat customers and referrals year after year.
The difference shows up in the results. Our technicians have logged real years on these systems, so they identify the actual fault the first time and fix it properly instead of throwing parts at your system until something sticks.
An oversized system short-cycles itself to death; an undersized one runs nonstop and never satisfies. Our team calculates the right capacity for your home and explains every option before you commit.
A maintained system simply lasts longer, and we'd rather earn your trust than sell you a condenser early. Every maintenance visit is thorough and documented. For older equipment, a $40 capacitor caught early can save a $2,000 compressor. Period.
