Fast and Reliable Furnace Repair
A broken furnace rarely happens at a convenient time. Whether it's a sudden cold snap or the middle of the night, losing heat is a stressful experience. Our team is equipped to diagnose and resolve furnace issues quickly and effectively. We arrive with fully stocked vehicles, prepared to handle the most common repairs on the spot, minimizing downtime and restoring your comfort as soon as possible.
You may need professional furnace repair if you notice:
- No Heat or Insufficient Heat: The most obvious sign of a problem, whether the system won't turn on or is blowing cool or lukewarm air.
- Unusual Noises: Banging, rattling, squealing, or grinding sounds can indicate mechanical issues like a loose part, a failing blower motor, or an ignition problem.
- Strange Odors: A strong smell of gas requires immediate attention and evacuation. Other musty or burning smells can point to dirty filters or electrical issues.
- Frequent Cycling: If your furnace turns on and off more frequently than usual, it could be a sign of a clogged filter, an improperly sized unit, or a faulty thermostat.
- Increased Energy Bills: A sudden, unexplained spike in your utility costs often means your furnace is working harder than it should to heat your home due to an underlying issue.
Our diagnostic process is meticulous. We don’t just fix the symptom; we find the root cause to ensure a lasting solution, servicing all major brands and models of natural gas and electric furnaces.

Comprehensive Furnace Maintenance for Peak Performance
The most effective way to avoid unexpected breakdowns is through proactive, professional maintenance. An annual furnace tune-up is a critical investment in your system’s longevity, efficiency, and safety. Our technicians perform a detailed inspection and cleaning service that goes beyond a simple filter change. We optimize your system to perform at its best, helping you save on energy costs and extending the life of your equipment.
Our thorough furnace maintenance checklist includes:
- Inspecting the Heat Exchanger: We carefully check for cracks or corrosion that could lead to dangerous carbon monoxide leaks.
- Cleaning and Adjusting Burners: Ensuring clean burners allows for efficient fuel combustion, improving performance and reducing waste.
- Testing Safety Controls: We verify that all safety switches and controls are functioning correctly to prevent potential hazards.
- Checking the Flue and Venting System: Proper ventilation is crucial for safely expelling exhaust gases from your home.
- Lubricating Moving Parts: Proper lubrication of motors and bearings reduces friction, prevents wear and tear, and ensures quiet operation.
- Verifying Electrical Connections: We tighten and inspect all wiring and electrical components to prevent shorts and system failure.
- Calibrating the Thermostat: An accurate thermostat ensures your home reaches the desired temperature without wasting energy.
- Cleaning or Replacing the Air Filter: A clean filter improves airflow, enhances indoor air quality, and reduces strain on the system.
Regular maintenance not only prevents the majority of costly repairs but also ensures your furnace operates safely, giving you peace of mind throughout the winter.
Professional Furnace Installation and Replacement
Even the best-maintained furnace has a finite lifespan, typically around 15-20 years. As your system ages, it becomes less efficient and more prone to breakdowns. If you are facing constant repairs or your heating bills are steadily climbing, it may be time to consider a new, high-efficiency furnace installation.
We can help you determine if replacement is the most cost-effective solution. Our process begins with a thorough assessment of your home's specific heating needs. We perform a precise load calculation to ensure your new furnace is perfectly sized for your space—a critical step that many overlook. An improperly sized unit will struggle to heat your home effectively, cycle inefficiently, and wear out prematurely. We guide you through selecting the right natural gas or electric furnace that fits your needs and budget, focusing on energy-efficient models that will provide long-term savings.
