The time to service it, before the first cold snap
Four ways people usually arrive on this page. Pick the one that sounds like your house.
Diagnosis and repair to get the house warm again.
Maintenance before the first cold week, not during it.
Installation for a first system, an addition, or a conversion.
Swapping a system that has reached the end of its life.
Furnaces, boilers, and gas water heaters all burn fuel, and anything that burns fuel can produce carbon monoxide when it goes wrong. You cannot smell it or see it, so the order you do things in matters more than the heat does.
Do not go looking for the source. Move everyone outside to fresh air, call 911 from outside, then count heads. Do not go back in until the responders say you can, and do not run the appliance again until it has been serviced.
Carbon monoxide has no smell and no color, and it reads like flu without the fever. If more than one person in the house feels it, or it improves when you go outside, get out to fresh air first and then call 911.
That is our call to take. If snow or ice has built up around the outside vent for a fuel burning appliance, clearing it is worth doing, because a blocked flue is one of the ways carbon monoxide backs up into a house.
Carbon monoxide guidance from the U.S. Consumer Product Safety Commission, which advises getting outside to fresh air first and calling 911 rather than looking for the source. Read the CPSC fact sheet.
Half of Northern Virginia runs on heat pumps, and this is the call we take most often in winter. It is almost always the system doing exactly what a heat pump does, and almost nobody is told to expect it.
A furnace burns fuel and pushes out air far hotter than you are. A heat pump moves heat rather than making it, and the air it delivers lands close to the temperature of your own skin. Warm enough to heat the house over time, not warm enough to feel hot on your hand. Almost nobody is told this when they get one, and it is the single most common call we take about heat pumps.
The outdoor coil picks up frost when it is cold and damp, so the system reverses itself for a few minutes to melt it off. You will see vapor rising outside and the air indoors may go cool while it happens. Then it goes back to heating on its own. Nothing is broken and there is nothing to do.
When it really is a problem. Call us if the house is not reaching the temperature you set it to over several hours, if auxiliary or emergency heat is running more or less constantly, if the outdoor unit is encased in solid ice rather than lightly frosted, or if the air at the register is genuinely no warmer than the room. Those are faults. Air that feels cool on your hand while the house slowly warms up is not.
If you have a furnace rather than a heat pump. Lukewarm air points somewhere else entirely, usually a clogged filter, a thermostat fault, a failing igniter, or a system shutting itself down on a limit switch. Our heating repair page covers what happens on a call, and the heat pump page is there if you are weighing one up.
Seasonal care, year round systems, and the equipment that sits on the same air handler your heat runs through.
A seasonal service before the cold arrives, which is also the inspection the CPSC says a fuel burning furnace should have every year.
Learn moreOne system that heats in winter and cools in summer, with no separate furnace and no fuel burning at all.
Learn moreSet the heat back overnight and while the house is empty, without anybody having to remember to do it.
Learn moreUltraviolet lamps fitted inside the air handler, aimed at the coil and drain pan. The same air handler moves your heat, so it runs in winter too.
Learn moreWinter heating dries a house out. This adds moisture back through the ductwork you already have, rather than filling tanks room by room.
Learn moreA furnace has a burner and a flue, and it also has a board, an igniter, and a circuit. We are licensed for both, so there is no second contractor to book and nobody to blame each other.
On a fuel burning system that means looking at the heat exchanger, the flue, and the venting, not just whether it lights and runs.
On a heating system that means the fault, whether it is worth fixing on a unit of that age, and what a replacement would actually involve. All of it agreed before anybody picks up a tool.
Heating work qualifies for our discount for active duty military and veterans. The program page carries the terms.

Verified Reviews
If your furnace is over 15 years old, needs frequent repairs, or your bills keep climbing, replacement often makes more sense. For newer systems, a repair is usually the smart call. We give you an honest assessment either way, and our decision tool can help.
At least once a year, ideally in fall before heating season. Regular maintenance keeps your system efficient and helps prevent breakdowns on the coldest nights. On a fuel burning system it is also the annual inspection the CPSC points to when it talks about carbon monoxide.
Common causes include a dirty filter, a thermostat issue, a failing igniter or heating element, or a system that is short cycling. If you have a heat pump rather than a furnace, air that feels cool at the register can also be perfectly normal, which is covered further up this page. Our technicians diagnose the cause quickly and explain your options before any work begins.
Often, yes. Modern heat pumps heat efficiently even in cold weather and provide cooling in summer too, making them a strong year round option for many local homes.
Yes. When your heat quits in dangerous cold, we offer fast emergency heating repair across Northern Virginia.
We are the same team in both seasons. Our air conditioning services cover the summer half, and the HVAC service agreement covers both, with priority scheduling when everybody else is calling at once.
