Had a new central air system installed last July and the entire experience was outstanding. The team showed up on time, explained every step, and left our home spotless. Our energy bills dropped noticeably the first month. Could not be happier with the quality of work.

Michael Brennan

Rydal, PA

AC Installation
Our furnace stopped working on the coldest night of the year. Called ChillTech Corporation and they had a technician at our door within an hour. He diagnosed the issue quickly and had it fixed the same night. Lifesavers — literally. Will never call anyone else.

Jennifer Walsh

Jenkintown, PA

Heating Repair
Signed up for their annual maintenance plan two years ago and it has been worth every penny. Both our AC and furnace are running more efficiently, and we have not had a single breakdown since. The technicians are always professional and thorough.

David Kim

Abington, PA

Maintenance
AC went out during a summer heat wave and I was dreading a long wait. They came out the same day, found a faulty capacitor, and had it replaced in under an hour. Fair pricing, honest assessment, and no upselling. This is how HVAC service should be.

Sarah Thompson

Glenside, PA

AC Repair
Replaced our 25-year-old furnace with a high-efficiency model. The installation crew was incredibly professional — they protected our floors, explained the new thermostat setup, and even hauled away the old unit. The difference in heating performance is night and day.

Robert Costello

Huntingdon Valley, PA

Heating Installation
A pipe issue caused our boiler to shut down on a Sunday evening. I expected to wait until Monday, but they answered right away and sent someone within the hour. The technician was friendly, knowledgeable, and fixed it fast. Outstanding emergency service.

Maria Gonzalez

Elkins Park, PA

Emergency Service
Got three quotes for a ductless mini-split system and ChillTech Corporation was the most thorough and competitively priced. The installation was clean and professional, and the system works perfectly. They even helped us get the manufacturer rebate. Highly recommend.

Thomas O'Brien

Willow Grove, PA

AC Installation
Been using them for annual tune-ups for five years now. Every visit, the technician takes the time to explain what they checked and any minor issues to watch. No surprise repairs, no scare tactics — just honest, reliable maintenance. A rare find these days.

Linda Patterson

Wyndmoor, PA

Maintenance
Our heat pump was making a terrible grinding noise. The tech diagnosed a failing blower motor and had the part in his truck. Fixed it on the spot. He also noticed our air filter was overdue and swapped it out at no extra charge. Excellent service from start to finish.

James Chen

Cheltenham, PA

Heating Repair
After another company misdiagnosed our AC problem twice, we called ChillTech Corporation for a second opinion. Their tech found the real issue — a refrigerant leak — and repaired it properly. The system has been running perfectly ever since. Wish we had called them first.
