Many Bristow homes pair a heat pump with a gas furnace, and a tune-up should cover both. Service First Heating & Air checks your furnace, your heat pump and the thermostat settings that decide which one runs. That way your backup heat is ready the first time a freezing night arrives, and you’ll see upfront pricing before any work.

In a Bristow home with a dual-fuel system, the gas furnace might run only a fraction of the heating season. That can make it easy to forget. But a furnace that sits idle for months still needs attention. Dust settles on burners and sensors, ignitors age, and small problems stay hidden until the day the heat pump hands off and nothing happens.
A fall tune-up gives our technicians a chance to fire the furnace, test every safety control and confirm that the heat pump and furnace trade off at the right time. It’s the best way to make sure your backup heat is actually ready. Our preventative maintenance page explains how ongoing plans keep you on schedule.

Bristow is mostly newer subdivisions and townhome communities, and many homes here use heat pumps with gas furnace backup. In that setup, your indoor furnace also serves as the air handler for the heat pump. Its blower moves air in every season, heating and cooling, even when the burners are off. So while the burners may rest, the blower, filter and coil work all year.
A good Bristow tune-up treats the system as one unit. We check the gas side for safe, clean combustion and the electric side for proper heat pump performance. Then we make sure the controls hand off smoothly between the two.
Virginia’s shoulder seasons make this especially important. On a fall day that starts near freezing and warms up by afternoon, your system may switch between heat pump and furnace more than once. Getting the settings right keeps you comfortable and avoids wasted energy.


A tune-up for a Bristow dual-fuel home covers more ground than a standard furnace check:
Staying on top of maintenance also helps both pieces of equipment last longer, which matters when you have two systems to protect.

I met Seth a few years ago when I had another company install a new AC unit improperly. He fixed it and ended up installing a new secondary unit for me a short time later. Ever since then I’ve been a faithful customer and go to Seth for all of our HVAC needs and concerns. I am so thankful to have found a solid company after having countless companies take my money and give me the run around. I cannot recommend Seth or this company enough!! They will take the absolute BEST care of you!!Posted on Google![]()

My heat pump broke in the middle of winter. I called several companies before this one and they all couldn't get to me for a whole month! I called this company and they were able to send someone to take a look at the heat pump the same day. This offered me a lot of relief as I wanted to resolve the broken heat pump as soon as possible so that I didn't have to wear a coat inside my own house or worry about frozen pipes. The technicians were all very respectful of my property and cordial. I ended up getting a new heat pump because we would have had to replace most of the parts of the old one. The price for the new heat pump was fair. Would definitely recommend giving these guys a shot.Posted on Google![]()

Make sure your backup heat is ready before you need it. Call (540) 690-4280 or book online today.
Yes. In a dual-fuel home, the furnace may run only on the coldest days, but it still needs to light reliably and burn safely when called on. Parts like ignitors and flame sensors can wear out or collect residue even during idle months. A yearly tune-up confirms your backup heat is ready before a freezing night.
In a dual-fuel system, we look at both. Many Bristow homes use heat pumps with gas furnace backup, and the two share the same blower, filter and controls. Checking only the furnace would miss half the picture. We make sure each part works on its own and that the hand-off between them happens at the right time.
It’s the outdoor temperature at which your system stops using the heat pump and starts using the gas furnace. Set it too low, and the heat pump struggles in the cold. Set it too high, and the furnace runs more than it needs to. During maintenance, we review this setting based on your equipment and comfort needs.
Check it monthly. Because a dual-fuel system uses the same blower and filter for heating and cooling, the filter works year-round, not just in winter. Many filters need changing every one to three months. In townhomes where the unit is in a closet or attic, a calendar reminder helps you stay on track.
Early fall works best. The summer cooling season is over, and you have time to handle any repairs before freezing weather. Booking early also gives us time to test the furnace side of your dual-fuel system while it’s still mild outside, so you aren’t finding out it won’t light on the first cold night.
