Furnace & Heating Repair in Gaithersburg, MD
Losing heat on a freezing Maryland night is more than uncomfortable — it can put your family and your pipes at risk. P&Y Heating and Cooling provides fast, licensed furnace and heating repair across Gaithersburg, and because we're available around the clock, you're not left waiting until morning.
Our technicians are trained to diagnose gas and electric furnaces safely. We check the ignition system, flame sensor, blower, thermostat, and safety controls, then explain exactly what failed and what the repair involves before we touch a wrench.
Common Furnace Problems We Fix
Some heating issues are simple; others involve safety systems that should only be handled by a licensed technician. Call us if you notice:
- No heat, or the furnace blows cold air
- The furnace short cycles — turning on and off repeatedly
- Yellow or flickering burner flame instead of steady blue
- Clicking, booming, or rattling on startup
- A burning or gas-like odor when the system runs
- The blower runs constantly or never engages
- A tripped high-limit switch or repeatedly tripping breaker
Our Furnace Repair Process
Heating equipment burns fuel and moves electricity — safety comes first on every call.
Safety check first
We inspect for gas odors, cracked heat exchangers, and combustion issues before anything else, because carbon monoxide and gas leaks are non-negotiable.
Diagnose the failure
We test the ignitor or pilot, flame sensor, gas valve, limit switches, blower motor, and thermostat to find the real cause of the no-heat or short-cycling problem.
Written repair options
You get a clear scope with parts and labor, plus an honest note if a repair on an aging furnace isn't the smart long-term move.
Repair and safety verify
After the fix we cycle the furnace, confirm safe combustion and proper airflow, and make sure every safety control is working before we leave.
Why No-Heat Calls Spike in Montgomery County
Maryland winters bring hard freezes and seasonal snowfall that regularly tops 20 inches, and furnaces that coasted through mild weather often fail on the first truly cold night. Aging ignitors, dirty flame sensors, and clogged filters are the usual culprits — small parts that stop a whole system.
Regular maintenance catches most of these before they leave you cold, but when a failure happens, we're ready 24/7 to restore heat quickly and safely.
When Furnace Repair Becomes Replacement
A cracked heat exchanger, a furnace over 15 years old with a major failure, or repeated repairs each season are signs it may be time to compare replacement. We'll never hide a safety issue, and we'll give you honest numbers so you can weigh a repair against a new, efficient system.
What Affects Furnace Repair Cost
Furnace repairs generally fall in the $160–$675 range, with diagnostics commonly $89–$175. Common parts like an ignitor or flame sensor run $115–$330. Your cost depends on:
- The failed component — a flame sensor is inexpensive; a blower motor or gas valve costs more
- Gas vs. electric furnace and the fuel type
- Accessibility of the equipment (tight attic or crawlspace installs take longer)
- Warranty status of the furnace and its parts
- Standard-hours vs. overnight emergency service

Huge thank you to Pedro! Our furnace stopped working and he came out fairly quickly, diagnosed the issue right away, and had everything up and running in no time. He was polite, thorough, and took the time to make sure we understood the issue and how to avoid it in the future.

Furnace Repair
We had a recent service call due to our heat not working, in freezing cold weather and a winter storm. Pedro came out and was very professional as he diagnosed the issue. He was able to get things working again in a short period of time. Excellent service from P&Y Heating and Cooling.

Heating System Repair
Pedro was incredibly knowledgeable, professional, and courteous. His quote was also very fair, coming in far below several other companies. I highly recommend him for anyone with complicated issues that many HVAC companies do not have the capacity to address, such as old hot water boilers and radiators.
