Furnaces

As a locally owned and family-operated company, we are committed to putting our customers and employees first, and that dedication shows in every furnace installation, repair, and maintenance job we complete. Whether you are dealing with an aging system that struggles to keep up or you need emergency service on the coldest night of the year, we offer fast response times and take full responsibility for our work.

Furnace Installation Done Right

A furnace installation is one of the most important investments you will make in your home. The process begins with a thorough assessment of your living space, including square footage, insulation quality, ductwork condition, window efficiency, and your household’s specific comfort needs. We perform a Manual J load calculation to determine the precise heating capacity your home requires. An oversized furnace cycles on and off too frequently, wasting energy and creating uneven temperatures, while an undersized unit runs continuously without adequately heating your home. Getting this calculation right is essential to long-term performance and efficiency.

Once we determine the correct system size, we walk you through available options including single-stage, two-stage, and modulating furnaces. Modulating furnaces represent the pinnacle of heating technology, adjusting their output in small increments to maintain a consistent temperature throughout your home. We handle every aspect of the installation process, from removing and properly disposing of your old equipment to configuring the new system, testing safety controls, and verifying airflow across every room. We take great pride in serving our community, and that includes ensuring every installation meets or exceeds manufacturer specifications and local building codes.

Furnace Repair and Diagnostics

Furnace breakdowns rarely happen at convenient times. Strange noises, inconsistent heating, frequent cycling, and unexpected shutdowns are all signs that something needs attention. Our technicians use advanced diagnostic tools to quickly identify the root cause of the problem, whether it involves a faulty ignitor, a cracked heat exchanger, a malfunctioning blower motor, or a thermostat communication issue. We are here to understand your situation and offer personalized service rather than pushing unnecessary replacements.

According to the U.S. Department of Energy, heating accounts for approximately 29% of a typical home’s energy consumption, making it the single largest energy expense for most households. A malfunctioning furnace does not just compromise comfort. It can significantly increase your utility costs and even pose safety hazards, particularly with gas furnaces where carbon monoxide leaks are a real concern. We prioritize safety in every repair, testing combustion levels and verifying proper venting before we consider a job complete.

Preventive Maintenance That Extends Furnace Life

The average furnace lifespan ranges from 15 to 20 years, but reaching that upper range depends heavily on regular maintenance. Industry data suggests that well-maintained furnaces retain up to 95% of their original efficiency throughout their service life. Our preventive maintenance visits are comprehensive and designed to catch small problems before they become expensive repairs. Here is what a typical maintenance visit includes:

1. Thermostat calibration and testing to ensure accurate temperature control throughout your home
2. Inspection and cleaning of the burner assembly to promote safe and efficient combustion
3. Heat exchanger examination for cracks or corrosion that could lead to carbon monoxide exposure
4. Blower motor and belt inspection to verify proper airflow and reduce strain on components
5. Air filter replacement or cleaning to maintain indoor air quality and system efficiency
6. Safety control and ignition system testing to confirm reliable startup and operation
7. Flue and venting inspection to ensure proper exhaust of combustion gases

Giving Back Through Warmth

We believe everyone deserves a warm home. Our community initiatives include providing free furnace installations to families in need during the winter season, contributing to the HVAC installation for the St. Jude Dream Home, and supporting the Children’s Justice Center’s new facility.
