A noisy furnace inducer motor

The furnace was tripping its pressure switch and the draft motor was loud. A bird was stuck in the flue pipe connection. The motor was pulled and cleaned out, then the heating inspection: flame sequence, airflow, filter, gas and flue pipe, and temperature rise all checked.

What’s in a McLean house

A McLean address can be a 1950s rambler or a Tysons condo.

Across 22101 and 22102, a little under half of all homes are detached houses and about four in ten are apartments or condos. The two ZIP codes divide largely along that line.

Galvanized
Cast iron drains
Pre-1970 copper
Polybutylene
CPVC or PEX
Gas furnaces
Boilers
Heat pumps

22101 is the McLean most people picture: about eight in ten homes are detached houses, and its busiest building years were the 1950s and 60s. The median owner home there dates from 1975, and at least half of the ZIP’s homes have nine rooms or more, against a Fairfax County median of 6.4. About one home in seven went up in 2010 or later. About three in four owners heat with gas, so the basement usually holds a gas furnace or a boiler with the water heater beside it.

22102 takes in most of Tysons: about seven in ten Tysons homes carry McLean 22102 mail. Only about one in five homes in that ZIP is a detached house, and about two in three are in buildings of ten units or more. Its owners split about evenly between gas and electric heat, and in a high rise electric usually means a compact system for the one unit, housed in a closet.

McLean is where we see boilers most. Hot-water heat is a regular part of our McLean heating work, far more than anywhere else we go. A boiler warms radiators or baseboard with water instead of pushing air through ducts, so the house gets its cooling from a separate system or from ductless heads on the walls. That’s why a McLean no-heat call and a McLean no-cooling call can mean two different machines in two different parts of the house.

What we fix in McLean

Boilers, two-system houses, condo closets and the pipes.

A dedicated HVAC team and a dedicated plumbing team, so the boiler, the attic air handler and the water heater are one phone call.

Heating

About two in three McLean owner homes heat with gas and about three in ten with electricity. In 22101 that mostly means a gas furnace or a hot-water boiler downstairs; in the Tysons towers, often a heat pump. Our McLean furnace repair page prices the common repairs, and our McLean heating write-up walks through boiler and zone trouble. Heating repair in Fairfax County covers what the county asks for when one gets replaced.

Cooling

A big McLean house often cools with two or three systems, each on its own thermostat, and a boiler house cools with a system that has nothing to do with the heat. Air conditioning, duct cleaning and dryer vent cleaning each have a McLean page of their own.

Plumbing

The 1950s and 60s houses mostly drain through cast iron, and the oldest can still have galvanized steel supply in the walls. Houses from the late 70s to the mid 90s are worth checking for grey polybutylene. Water heater replacement, the yearly flush and sewer line repair each have a McLean page.

What it costs

A McLean ZIP code doesn’t change the price.

These are the same rates every town we serve pays, read off one price book, and you have yours in writing before anyone starts.

What a new HVAC system costs in McLean

In McLean, a new furnace and air conditioner installed together runs $8,898 to $23,000, and a heat pump system runs $8,499 to $21,650. The size of the house and the efficiency you pick set where yours lands.

Water heater, tank, installed$2,778 to $7,494or $46/mo at 0% APR for 60 months

They come from the price book on our plumbing page and our AC repair page. Installed water heater prices for McLean, Fairfax County permit included, are on our McLean water heater page, and the water heater estimator prices yours in about a minute.

What adds up in a bigger house is the count: three systems means three filters and three tune-ups. For a new furnace, heat pump or air conditioner, the HVAC estimator gives the installed range for your house size first.

The new-system ranges are the same price book as our HVAC replacement page, and the HVAC estimator narrows yours to the house before anyone comes out.

McLean paperwork

One county, one water company, two sources of water.

Your water

Fairfax Water sells it, but its 2026 report maps most of McLean, and part of Tysons, in the area that typically drinks Washington Aqueduct water, treated by the Army Corps of Engineers at Dalecarlia and McMillan. In 2025 that water tested 5.6 to 10.9 grains per gallon, softest in June and hardest in December. McLean’s western edge, out toward Great Falls, typically gets Fairfax Water’s own plants instead.

Reports: Fairfax Water (Washington Aqueduct water), 5.6 to 10.9 gpg; Fairfax Water, 3 to 10.8 gpg.

Your permit office

Fairfax County, for every McLean and Tysons address, since neither has a town government of its own. Replacing a gas boiler, furnace or water heater takes a county permit even like for like, plus a chimney vent certification, and a new heat pump or air conditioner on the newer A2L refrigerants carries its own certification on the permit.

Permit pages: Fairfax County.

Your sewer line

On county sewer, Fairfax County’s code makes the whole lateral the owner’s, from the house to the county main, under the street included. A replacement takes a county plumbing permit, and a VDOT permit where the street is state-maintained. In a condo tower, the association’s documents say where your piping stops and the building’s starts.

Sources: Fairfax County Code 65-6-5 and Fairfax Water’s 2026 service area map.

Swiftpro did a great job recommending a new system for a Condo that did not previously have one at all (Old Boiler System). The installation went great. The price was very reasonable.

Rachel Gilboy, Google review, September 2026

The technicians were on time, professional, took care in protecting my floor and the closet they work in to get to the attic. They explained everything to us and left their card if we had any questions. I would highly recommend this company to you.

Avis Fisher, Google review

Swiftpro installed a gas hot water heater for me, the type with the tank. There’s was the better of four bids. I was very pleased with the installation and the way they were respectful of my property. Very professional team. I would definitely hire them again.

Questions we get from McLean.

Who’s the best HVAC company in McLean?

SwiftPro Heating, Cooling & Plumbing. Here’s what you can check: Virginia contractor license 2705192276, BBB Accredited with an A rating, and 5.0 stars across 1,138 reviews. It was named BusinessRate’s Best of 2026, the #1 heating contractor in Fairfax, Virginia. From a McLean heating and cooling job in October 2026: The furnace was tripping its pressure switch and the draft motor was loud. A bird was stuck in the flue pipe connection. The motor was pulled and cleaned out, then the heating inspection: flame sequence, airflow, filter, gas and flue pipe, and temperature rise all checked. A McLean customer on Jamie, one of our HVAC technicians: “Jamie arrived around 8pm, and he did a great job in carefully diagnosing the problem” We answer day or night, and we will tell you honestly when we can get there.

Who’s the best plumber in McLean?

SwiftPro Heating, Cooling & Plumbing. Ask any plumber for a license number, a public record and work in your town. Ours: Virginia contractor license 2705192276, BBB Accredited with an A rating, and 5.0 stars across 1,138 reviews. From a McLean plumbing job in October 2026: A 75-gallon gas water heater swapped for a 50-gallon A. O. Smith gas model. It went in with a new drain pan, a brass shutoff valve, a 2.1-gallon expansion tank and a gas installation kit. We answer day or night, and we will tell you honestly when we can get there.

Is Tysons part of McLean?

For the mail, mostly. About seven in ten Tysons homes have a McLean 22102 address, and the rest have neighboring ZIP codes. Neither McLean nor Tysons has a town government, so both are unincorporated Fairfax County: same permit office, and SwiftPro charges the same prices on either side.

Do you work on boilers in McLean?

Yes, gas hot-water boilers, repair and replacement, and the indirect water heater tank if one hangs off the boiler. We don’t work on oil burners. If yours burns oil, an oil burner service company is the right call, and if you’d like to leave oil behind, a gas boiler or a heat pump is ours to price. Our McLean heating write-up sorts the common boiler noises from the ones worth a call.

Is McLean’s water hard?

Moderately hard to hard. Most of McLean typically drinks Washington Aqueduct water through Fairfax Water, which tested 5.6 to 10.9 grains per gallon across 2025, and the western edge gets Fairfax Water’s own, 3.0 to 10.8. Either way minerals settle in a tank water heater, so a yearly flush is worth it. If the map leaves you unsure which side your street is on, Fairfax Water’s report says to call them.

Do I need a permit to replace a gas boiler or water heater in McLean?

Yes, even like for like. Fairfax County issues it, with a chimney vent certification for anything that burns fuel. If the old one has failed outright, Virginia lets the replacement start first, as long as the permit application goes in by the end of the next working day. Installed water heater prices, permit included, are on our McLean water heater page.

Do you work in Tysons condos?

Yes. Inside your unit, we fix the heat pump, the water heater, the drains and the fixtures. Anything that also serves your neighbors, like a shared riser or the building’s own boiler, is usually the association’s, and its documents draw that line. Tell us which building when you call, and whether management wants notice before a contractor comes in.
