Furnaces

A reliable furnace is essential for staying warm, comfortable, and safe during the harsh DeKalb winters. Our team has the necessary experience repairing most makes and models of gas and electric furnaces — if your system experiences uneven heating, strange noises, energy consumption spikes, and other issues, our technicians will diagnose and resolve the underlying problem.
To keep your system in good shape throughout the year and avoid preventable breakdowns, we offer furnace tune-ups that include furnace cleaning, lubricating, adjustments, and calibration.
If you need a replacement system or want to upgrade to a high-efficiency furnace, a technician can assess your home’s size, layout, existing ductwork, insulation, and other factors to calculate your home’s heating load precisely. Then, they help you choose a new model based on your space, preferences, and budget.
Heat pumps
Heat pumps are an energy-efficient option that’s increasingly popular in DeKalb homes. Operating on a refrigerant-based heat-exchange process, heat pumps transfer heat to and from your home as needed to heat or cool your space, depending on the season and your home’s needs. In other words, heat pumps provide both heating and cooling in a single unit, delivering year-round comfort.
At G&R Heating and Air, we offer maintenance and repair services to optimize the efficiency, performance, and longevity of your heat pump. If you’re upgrading from an existing unit or switching from another system type, our technicians help you select a new unit that’s sized to your home’s needs.

Frequently Asked Questions
How often should I schedule HVAC maintenance?
ACs typically need service at least once per year — ideally in the spring, before the summer temperatures and peak cooling season ramp up. Likewise, furnaces or other heating equipment should be serviced before winter in DeKalb.
How do I know if my AC needs repair?
Several signs indicate that your AC needs repair, such as:
- Insufficient cooling or warm air
- Strange noises
- Moldy or other unpleasant odors
- Reduced airflow
- Frequent cycling
- Leaking water or frozen coils
- Unresponsive or faulty thermostat
My system is making a strange noise. Is that a problem?
New and odd noises can be a problem. HVAC systems typically operate at a low hum, no louder than a conversation, during cooling or heating cycles. You may also hear a click when a cycle initiates. However, banging or popping sounds from your furnace may indicate small explosions caused by delayed ignition in the combustion chamber. Grinding, squealing, and similar noises suggest mechanical problems.
How can I tell if I need a new furnace or air conditioner?
Your furnace or air conditioner may be due for replacement if it’s near or past its expected service life. HVAC equipment gradually wears out as it approaches the end of its expected lifespan, reducing its ability to meet your home’s heating or cooling needs. This strain results in high energy bills, inconsistent temperatures, unusual noises, nonstop cycles, and other problems. Our team can assess whether your system is ready for replacement and help you select a new unit.
