Lewiston sits near Lake Anna in southwestern Spotsylvania County, and many homes here are rural properties or lake-area houses, with some seasonal places in the mix. The most common repair call we hear from this part of the county starts the same way: the owner arrives on a cold weekend, turns up the thermostat and nothing happens.
Sometimes the fix is small, like a dirty flame sensor or a tripped switch. Sometimes a part has worn out while the system sat. Either way, we find the cause, show you what we found and give you upfront pricing before we start. Our heating services page covers everything else we do to keep homes warm.
Your safety and comfort come first. Our team is fully insured and trained to handle all AC services with precision.
We use only trusted brands like Rheem to ensure long-lasting performance and energy efficiency.
From 10% discounts for veterans and seniors to flexible financing plans, we make cool comfort affordable.
Seasonal tune-ups and regular maintenance keep your system efficient, reliable, and ready for summer.
Furnaces that go weeks without running tend to fail in a few predictable ways:
Lake-area and seasonal homes put a different kind of stress on a furnace. Instead of running steadily all winter, the system may sit for long stretches, then be asked to heat a cold house quickly. That hard start is when weak parts give out. Humid summers near the lake can also leave moisture in closets and crawlspaces, which is tough on electrical connections and metal parts over time.
Lewiston houses tend to follow the rural Spotsylvania pattern of heat pumps, propane furnaces or a pairing of the two. Propane furnaces need a steady fuel supply and a properly adjusted gas valve, while a heat pump with electric backup has its own set of controls to check. Our technicians work on all of these, so one call covers whatever you have.


Most furnace problems in seasonal homes are repairable, and we’ll say so when that’s the case. A new flame sensor or ignitor can have a furnace running again the same visit.
A new furnace starts to make sense once the heat exchanger has cracked, an aging unit needs an expensive component, or the same system keeps calling you back for fixes. In that case we’ll put repair and replacement next to each other, show you equipment from trusted brands such as Rheem, and explain flexible financing. We never push a new system when a fair repair will do.

Homeowners around the lake rate us highly on Google because we keep things simple. Our technicians are licensed and insured, our pricing is upfront, and veterans and seniors get a 10% discount. We also work on heat pumps, air conditioners and indoor air quality, so you have one team for the whole house. See everything we offer on our Lewiston HVAC page.

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![]()

No one wants a chilly weekend at the lake. Phone (540) 690-4280 or tell us about the problem online, and we’ll set up a time to come out.
After a long idle stretch, the usual suspects are a dirty flame sensor, a cracked ignitor, a dead thermostat battery or a problem with the fuel supply. In lake-area and seasonal Lewiston homes, mice can also move into a quiet furnace and damage wiring. A technician can test each part and find the one that’s stopping the startup.
This is often a flame sensor problem. The sensor has to confirm the flame within a few seconds, and a light coating of residue can stop it from doing so. It can also point to low gas pressure from the tank or regulator. Cleaning or replacing the sensor is a fairly quick repair, but gas pressure should always be checked by a professional.
Yes. Many owners of seasonal and lake-area homes in Lewiston schedule a visit before the first cold weekend of the year. We’ll need a way into the home, and we’ll let you know what we find. That way the heat is ready when you get there instead of failing on your first night.
A light dusty smell for a few minutes on the first run of the season is common, since dust settles on the burners and heat exchanger. If the smell is strong, smells like burning plastic or lasts longer than a short while, turn the furnace off and call us. That can point to an electrical or motor problem.
Get everyone out first. Skip the light switches, phones and anything that could spark, and once you’re outside, call 911 or your propane company. Once the leak is handled, we can inspect the furnace, gas valve and connections before it runs again. It’s also smart to keep working carbon monoxide detectors near sleeping areas in any home with a fuel-burning furnace.
