Every install we run in McLean includes the core mechanical work, the permit, and the commissioning documentation. Add-ons like duct sealing, electrical upgrades, and new line sets are quoted separately so you can see exactly what you are paying for.
We measure square footage, insulation, window area, and orientation, then size the system to the result. This is the single biggest factor in whether your new heat pump holds temperature on a 15-degree night without leaning on aux heat.
We file the mechanical permit, install to Virginia code, and schedule the final inspection. You get the signed inspection card, which matters when you sell the house and a buyer's agent asks for permitted work.
We recover the old charge with a recovery machine, pull a deep vacuum with a vacuum pump, and charge by weight plus superheat and subcooling verification. No guesswork, no topping off a leaking system and calling it done.
We pair the outdoor condenser and indoor air handler as an AHRI-certified match so the rated SEER2 and HSPF2 numbers hold up. Mix-and-match systems often miss the efficiency they advertise, and they can complicate warranty claims.
You get a sheet with static pressure, temperature split, superheat, subcooling, and defrost timing. If something drifts in year one, we compare against those baseline numbers instead of guessing what changed.
We calibrate the thermostat, set a sensible schedule, and show you filter size, filter location, and how to read a fault code. Fifteen minutes of walkthrough saves a lot of service calls later.
Heat Pump Installation McLean VA is the full mechanical job of removing an old outdoor condenser and air handler, sizing a new system to your home's actual load, running or reusing line sets, wiring the low-voltage controls, and commissioning refrigerant charge to manufacturer spec. It is not a box swap. We run a Manual J load calculation, check static pressure in your existing ductwork, and verify the electrical panel can carry the new compressor's locked-rotor amps before we ever set the pad.
Most McLean homes we see are running 12- to 18-year-old equipment that still cools but costs a fortune to heat. If your system is short-cycling, blowing lukewarm air in January, or tripping the breaker on cold mornings, a new heat pump installation McLean Virginia is usually cheaper than another season of repairs. We also handle HVAC heat pump install McLean jobs where ductwork needs sealing, because a 20% duct leak will erase half the efficiency of a brand-new unit.
From the first phone call to the final commissioning report, here is exactly what happens when you book a heat pump replacement in McLean with us.
Schedule
Call or book online — a real human picks up and confirms a 2-hour arrival window.
Diagnose
Licensed tech inspects on-site, then walks you through the cause and your options.
Fix
The job is completed to code and done right the first time — no shortcuts, no surprises.
Guarantee
Every job backed by a written workmanship warranty — and we stand behind it.
Manifold gauge set
Used to read suction and liquid pressures during charging, then confirm superheat and subcooling against the manufacturer's target for the outdoor temperature.
Vacuum pump
Pulls the line set and indoor coil down to a deep vacuum before charging. Skipping this step leaves moisture in the system and shortens compressor life.
Refrigerant recovery machine
Recovers the old R-410A charge from your existing system so it can be reclaimed properly instead of vented. Required under EPA Section 608 rules.
Duct pressure gauge
Measures static pressure at the return and supply to catch ductwork restrictions before they choke a new system's airflow and efficiency.
Leak detection electronic detector
Finds refrigerant leaks at joints, coils, and Schrader ports on existing systems so we know whether the line set can be reused or must be replaced.
Thermostat calibration tool
Verifies the thermostat is reading room temperature accurately and cycling the system at the right differential, which prevents short cycling after install.
Manual J load calculation
We measure the house room by room, factor in insulation, glazing, and orientation, and size the equipment to the calculated load. This is the step that separates a system that holds temperature from one that runs nonstop.
AHRI-matched system pairing
We pair the outdoor unit and indoor air handler as an AHRI-certified combination. That keeps the rated SEER2 and HSPF2 numbers honest and avoids warranty disputes down the road.
Deep vacuum and weigh-in charging
We pull a deep vacuum, verify it holds, then charge by weight and fine-tune with superheat and subcooling readings. No topping off, no guessing by feel.
Commissioning documentation
Every install ends with a written sheet: static pressure, temperature split, superheat, subcooling, and defrost timing. It is your baseline and our accountability record.
01
What we do: We run a load calc, check attic access and drain routing, and install a matched split system with a new float switch and secondary drain pan. We also seal the accessible duct runs while the attic is open.
→ The house holds temperature within 2 degrees, the attic stays dry, and the homeowner avoids the mid-winter emergency call they were bracing for.
02
What we do: We size and install a ductless mini-split head for the new space, run the line set through a closet chase, and commission the zone with documented charge and airflow.
→ The addition heats and cools independently, the rest of the house is not thrown out of balance, and the homeowner controls the new zone from a phone.
03
What we do: We test the compressor windings, capacitor, and contactor, confirm the compressor is failing, and quote a replacement with a new disconnect and whip to bring the electrical side up to code.
→ New system, new electrical, permitted and inspected. No more breaker trips, and the aux heat no longer runs all night.
04
What we do: We quote a variable-speed cold-climate heat pump sized to the house, verify the panel capacity, and pull the Fairfax County permit. We also register the manufacturer warranty at commissioning.
→ Heating costs drop noticeably, the system qualifies for the credit, and the warranty is registered in the homeowner's name, not ours.
McLean sits in a mixed-humid climate with real winters. January lows land in the teens, July afternoons hit the mid-90s, and the shoulder seasons swing 30 degrees in a day. That range is exactly what a heat pump is built for, but only if it is sized and charged correctly. Most of the housing stock here is 1950s to 1990s construction, and we regularly find undersized returns, leaky duct joints, and air handlers squeezed into attic closets with barely enough clearance for a filter change. We handle HVAC heat pump install McLean jobs with that reality in mind: we measure static pressure, seal what we can reach with duct sealant, and route condensate drain lines so they actually drain. Fairfax County requires a mechanical permit and inspection for a changeout, and we pull it every time. If you are comparing heat pump system installation near me McLean options, ask each contractor whether they run a Manual J and pull the permit. The answers tell you a lot.
Langley Forest
Larger lots and mature trees mean condenser pads often sit under leaf drop. We spec clearance and recommend a leaf guard so the coil does not clog by November.
Chesterbrook
Many 1960s and 1970s ramblers here have attic air handlers with tight access. We plan the removal and replacement path before install day so nothing gets damaged.
West McLean
Additions and finished basements are common. We check whether the existing trunk line can carry the new load or whether a zone damper or mini-split makes more sense.
Salona Village
Some homes still have older electrical panels. We verify capacity for the new compressor's locked-rotor amps and quote a panel or circuit upgrade if needed.
Freeze-thaw cycles from December through March
Defrost cycle performance matters more here than in milder parts of Virginia. We verify board timing and sensor operation at commissioning so the coil does not ice over during a long cold snap.
Humid summers with 90-plus degree afternoons
Correct refrigerant charge and clean coils are the difference between a system that holds 72 degrees and one that runs all afternoon. We document superheat and subcooling on every install.
Older ductwork with leaky joints and undersized returns
A new high-efficiency unit on bad ductwork underperforms. We measure static pressure and seal accessible leaks so the equipment actually delivers its rated capacity.
Fairfax County mechanical permit and inspection requirement
We file the permit and schedule the inspection as part of the job. It adds a step to the timeline, but it protects you at resale and confirms the work meets Virginia code.
Most McLean homeowners call us because something is already failing. Here are the four problems we hear about most, and what a properly installed replacement does about each one.
Problem
You wake up to a 62-degree house, aux heat runs nonstop, and the electric bill spikes. A stuck reversing valve or failed defrost board rarely fixes itself.
Our Fix
We test the reversing valve, defrost control board, and refrigerant charge. If the unit is past its service life, we quote a new heat pump installation McLean Virginia with a modern defrost algorithm that handles McLean's freeze-thaw cycles cleanly.
Problem
Ice builds on the outdoor coil, capacity drops, and the system runs longer to hit setpoint. Repeated freeze-ups stress the compressor and shorten its life.
Our Fix
A new system with a working defrost cycle and correct charge stops the icing. We also check the outdoor unit's clearance and drainage, because a unit sitting in a snowdrift in a West McLean side yard will ice up no matter how good the board is.
Problem
An aging compressor and leaking ductwork can add 30% or more to winter bills while rooms still feel uneven. You pay more and stay less comfortable.
Our Fix
We run a load calc and a duct pressure test, then install a right-sized, AHRI-matched system. Sealing leaks with duct sealant and balancing dampers often recovers half the efficiency a new unit alone would deliver.
Problem
Capacitor, contactor, and blower motor failures stack up. Once you are past two repairs in a season, the math usually favors replacement over another fix.
Our Fix
We give you a straight comparison: repair cost versus a new install with warranty. If repair wins, we repair. If replacement wins, we quote a heat pump system replacement McLean Virginia with financing options and a firm install date.
A correctly installed heat pump cuts winter electric bills, holds temperature within 2 degrees, and qualifies for federal tax credits through 2026. Here is what you actually get when the job is done right.
Lower winter bills
A modern variable-speed heat pump with a properly charged R-410A or R-32 system can cut heating costs 25% to 40% versus a 15-year-old unit running electric resistance backup. In McLean, where January lows hit the teens, that difference shows up on every Dominion Energy bill from December through March.
Fairfax County permits pulled
Every heat pump system installation near me McLean job we run includes the Fairfax County mechanical permit and final inspection. That matters at resale: an unpermitted install can stall a closing or force a buyer credit. We schedule the inspection and hand you the signed card.
Correct sizing, not guesswork
Oversized units short-cycle, undersized units run nonstop. We measure square footage, window orientation, insulation values, and duct static pressure, then match capacity to the Manual J result. That is how you get a system that holds 70 degrees on a 15-degree night without aux heat screaming.
Warranty that actually pays
We register the manufacturer parts warranty and back labor with our own workmanship coverage. If a capacitor, contactor, or reversing valve fails inside the term, you are not paying retail for the fix. Ask us for the warranty sheet before we start, not after.
Typical 2026 pricing in McLean runs $6,800 to $14,500 for a full split-system changeout, all-in. That range covers equipment, labor, the Fairfax County permit, refrigerant, and commissioning. Where you land depends on system size, efficiency tier, whether the line set can be reused, and whether ductwork or electrical needs work. We give you an itemized written price at the estimate, not a ballpark that grows on install day.
Typical Investment Range
$6,800 - $14,500 depending on system size, efficiency tier, and any ductwork or electrical work
A correctly sized, permitted, and commissioned heat pump pays back through lower winter bills, fewer emergency calls, and a clean inspection record at resale. The cheapest quote is rarely the cheapest system once you factor in a second visit.
What changes the price
System size and capacity
A 2-ton system for a small rambler costs less than a 4-ton system for a two-story colonial. The Manual J load calculation determines the size, and size drives both equipment cost and labor time.
Efficiency tier
Single-stage, two-stage, and variable-speed systems sit at different price points. Higher tiers cost more upfront but cut winter runtime, and some qualify for federal tax credits that narrow the gap.
Line set condition
If the existing line set passes a pressure test and is the right size, we reuse it and save you money. If it is undersized, kinked, or leaking, a new line set adds material and labor.
Ductwork condition
Leaky joints and undersized returns reduce real-world efficiency. Sealing accessible ductwork with duct sealant and balancing dampers adds cost but often recovers more efficiency than upgrading the equipment tier.
Electrical upgrades
Older panels sometimes cannot carry a new compressor's locked-rotor amps. A new circuit, disconnect, or whip is quoted separately so you see the number before we start.
Access and removal
An attic air handler with a tight scuttle takes longer to remove and replace than a closet unit. We plan the path at the estimate so the labor number is realistic, not optimistic.

Quoted a heat pump replacement in McLean on a Tuesday and installed it that Friday. They pulled the Fairfax County permit, ran a load calc, and left the commissioning sheet on the counter. No surprises on the final bill.
Yelp ★★★★★4.8
Our old unit died in a cold snap. They came out the same day, confirmed the compressor was gone, and had a new system in two days later. The crew was clean and the attic looked better than when they started.
BBB ★★★★★4.9
Third quote we got, and the only one that measured static pressure. They sealed two duct leaks and balanced the dampers. Upstairs finally matches downstairs, and the winter bill dropped about $150 a month.
Google ★★★★★5.0
Installed a Mitsubishi mini-split for our addition. Clean line set, no drywall damage, and they walked us through the thermostat. When a head threw a code, they came back next morning under warranty at no charge.
Our techs hold NATE certification and EPA Section 608 certification, and we work under a Virginia HVAC contractor license with Fairfax County permits on every install. We have commissioned hundreds of residential splits and ductless mini-splits across McLean, from Chesterbrook ramblers to Potomac Hills two-story colonials. We carry AHRI-certified matched systems so you get the rated efficiency, not a mix-and-match that underperforms the label.
Real experiences from customers who chose our Heat Pump Installation services.
“Our 16-year-old unit finally quit in November. They came out the same day, ran a load calc, and had a new Carrier system in three days later. The install crew pulled the Fairfax County permit and left the inspection card on the kitchen counter. First winter bill was $180 lower than last year.”

“We needed a heat pump replacement in McLean and got three quotes. These guys were the only ones who measured static pressure and actually looked at our ductwork. They sealed two leaks and balanced the dampers. Upstairs is finally the same temperature as downstairs.”
Marcus T.
Homeowner, Chesterbrook
“They installed a Mitsubishi ductless mini-split for our third-floor addition. Clean line set run, no mess, and they walked me through the thermostat schedule. When one head threw a code a month later, they came back the next morning under warranty, no charge.”
