Our technician arrives at your home with a fully stocked service vehicle ready to diagnose the problem on the spot. We start by checking your thermostat to make sure it is sending the right signal to the furnace. Then we test whether the furnace actually fires up and produces heat. If it does not, we check the ignition system, flame sensor, and gas valve one by one.
Once we identify the issue, we explain it to you in plain terms before doing any work. Common causes of no heat include a faulty igniter, a dirty or failing flame sensor, a bad gas valve, or problems with the blower motor that prevent warm air from circulating. For most repairs, we can complete the work the same day. If a special part is needed, we order it quickly and schedule a follow-up visit at your convenience.

What causes a furnace to stop producing heat?
Several things can cause this. A faulty thermostat, a dirty or failing flame sensor, a bad igniter, a closed gas valve, or a broken blower motor can all prevent your furnace from heating your home. A professional inspection identifies the exact cause.
How fast can someone come out to fix my furnace?
We prioritize same-day service for heating emergencies. Many common parts are in our vehicles, so repairs often finish in one visit. Call (412) 946-2160 to schedule service.
Should I repair or replace my furnace if it will not heat?
If your furnace is less than 15 years old and the repair cost is reasonable, fixing it makes sense. If the unit is older, needs frequent repairs, or is losing efficiency, replacement may cost less over time. We help you weigh these options with no pressure to upsell.
Is it dangerous if my furnace will not heat?
It depends on the cause. If you smell gas, leave your home immediately and call us from outside. If the issue is mechanical with no gas smell, it is not an immediate safety hazard, but you should schedule repair soon to restore heat and avoid frozen pipes.
We don’t upsell—we listen, recommend smart solutions, and stand behind our work.

Electric furnaces are increasingly popular throughout Western Pennsylvania due to their clean operation and reliability in areas where natural gas lines aren’t readily available. Our electric furnace repair specialists understand the unique challenges these systems face, from heating element failures to control board malfunctions that can leave your home uncomfortably cold during harsh Pennsylvania winters.
Unlike gas systems, electric furnaces rely entirely on electrical components, making them susceptible to power fluctuations common in rural areas around Murraysville and Monroeville. Our technicians are equipped to diagnose issues with heating elements, sequencers, and blower assemblies that are specific to electric units. We also address problems with electric furnace thermostats and safety switches that can prevent proper operation.
When your electric furnace needs attention, our team provides comprehensive diagnostics and repairs that complement our broader furnace repair services. We understand that electric heating systems often work in conjunction with air conditioning systems, so we evaluate your entire HVAC setup for optimal performance. Our repair approach also considers the importance of proper ductwork maintenance to ensure efficient heat distribution throughout your home, which is especially critical for electric systems that can be more expensive to operate than gas alternatives.
Furnace emergencies don’t wait for convenient hours, especially during Western Pennsylvania’s unpredictable winter weather patterns. When temperatures plummet unexpectedly in areas like the Pittsburgh area or when ice storms knock out power and affect heating systems, our emergency furnace repair team is ready to respond 24/7 to restore warmth to your home.
Emergency situations often involve complete system failures, dangerous gas leaks, or carbon monoxide concerns that require immediate professional attention. Our emergency technicians carry fully stocked vehicles with common replacement parts and diagnostic equipment to handle urgent repairs on-site. We prioritize safety above all else, especially when dealing with gas furnaces that may pose health risks to your family.
Our rapid response service covers everything from sudden blower motor failures to igniter problems that leave you without heat. We understand that emergency repairs often reveal underlying issues that may require follow-up with our comprehensive furnace repair services or even system replacement. While addressing your immediate heating crisis, we also perform safety inspections to ensure your system operates reliably going forward. Our emergency service includes temporary heating solutions when needed and coordination with our maintenance team for preventive care to avoid future emergency situations.
The blower motor serves as the heart of your furnace’s air circulation system, and when it fails, even a perfectly functioning heating system can’t distribute warm air throughout your Western Pennsylvania home. Blower motor problems are particularly common in older homes throughout the region, where motors work overtime during extended heating seasons and may struggle with the dust and debris that accumulate in ductwork systems.
Our blower motor repair service addresses various issues including worn bearings, faulty capacitors, and motor overheating that can cause complete system shutdown. We diagnose problems ranging from unusual noises and reduced airflow to complete motor failure that leaves your furnace running but producing no heat distribution. Our technicians are experienced with both single-speed and variable-speed blower motors, understanding how each type integrates with modern HVAC systems.
Blower motor issues often indicate broader system problems, which is why our repair approach includes comprehensive evaluation of your entire heating system. We frequently coordinate blower motor repairs with air scrubber installation to remove debris that may have contributed to motor strain. Our service also considers how blower motor performance affects your air conditioning system during warmer months, since the same motor typically serves both heating and cooling functions. We recommend regular maintenance to extend blower motor life and improve overall system efficiency.
Flame sensors are critical safety components in gas furnaces that detect whether the burner has successfully ignited, preventing dangerous gas buildup in your home. Throughout Western Pennsylvania’s heating season, these sensors can become coated with carbon deposits or corrosion, causing them to fail and shut down your furnace even when all other components are functioning properly.
Our flame sensor replacement service addresses this common but often misdiagnosed problem that can leave homeowners frustrated when their furnace cycles on and off repeatedly without producing heat. The sensor’s location near the burner assembly makes it particularly susceptible to contamination from dust, pet hair, and other debris that circulates through your home’s air system. Our technicians use specialized tools to safely access and replace these sensors while ensuring proper positioning for reliable operation.
Flame sensor problems often occur alongside other furnace issues, making professional diagnosis essential to avoid unnecessary repairs. Our replacement service includes thorough testing of the ignition system and evaluation of factors that may have contributed to premature sensor failure. We coordinate flame sensor replacement with comprehensive gas furnace services to address underlying issues. Our approach also considers how proper air duct maintenance can reduce contamination that affects sensor performance, and we often recommend regular tune-ups to prevent future sensor problems through proactive cleaning and adjustment.
Heat exchangers represent the most critical component of your furnace, responsible for safely transferring heat from combustion gases to the air circulating through your home. In Western Pennsylvania’s climate, where furnaces operate extensively throughout long heating seasons, heat exchangers face significant stress from repeated heating and cooling cycles that can eventually lead to cracks or other structural failures.
Heat exchanger problems are among the most serious furnace issues, as damaged exchangers can allow dangerous carbon monoxide to enter your home’s air supply. Our heat exchanger repair service begins with comprehensive inspection using specialized cameras and testing equipment to identify cracks, corrosion, or other damage that may not be visible during routine maintenance. We understand that heat exchanger issues often indicate the need for complete system evaluation and potential replacement.
Given the complexity and safety implications of heat exchanger repairs, our service includes detailed analysis of whether repair is cost-effective compared to complete furnace replacement. We coordinate our heat exchanger services with comprehensive system inspections to identify contributing factors such as improper installation or inadequate maintenance. Our approach also considers how heat exchanger efficiency affects your overall energy costs and integrates with cooling system performance. We provide detailed recommendations for preventive maintenance to maximize heat exchanger lifespan and ensure safe operation of your heating system.
