AC & Heating Repair in McLean, VA

When your air conditioner quits on a humid August afternoon, nobody searches “ac repair mclean va” for fun — they need cooling restored today, not next week. Golden Arrow Service has kept Northern Virginia homes comfortable since 1999, and our shop at 8740 Wolf Trap Road in Vienna sits roughly five miles from most McLean neighborhoods. That’s why we offer genuine same-day AC and furnace repair across Langley Forest, Franklin Park, Chesterbrook, Potomac Hills, and West McLean — plus 24/7 emergency service, free second opinions, and financing.

McLean’s homes aren’t typical, and neither are their HVAC problems: one street can hold a 1960s split-level with an aging furnace and, two doors down, a brand-new custom home on the same lot. We size, repair, and replace systems for both — checking equipment age first.

Same-Day AC Repair in McLean

Same-day AC repair in McLean works because we’re close. Our technicians roll out of our Vienna shop with fully stocked trucks, so calls from Chesterbrook, Potomac Hills, and beyond are short drives. Call (703) 782-5028 before noon and we aim to be at your door that afternoon.

The air conditioning repair calls we run most here mirror the housing stock: aging R-22 systems in 1960s–70s originals, zone-damper failures in large multi-zone customs, clogged condensate drains in July and August, and capacitors fried by storms. McLean’s lots — a third of an acre up to three-plus in Langley Forest — mean bigger systems and more ductwork, where diagnosing airflow across zones matters more than swapping parts. Our AC repair in McLean starts with a diagnostic ($89–$249); most repairs land between $149 and $2,300. If the fix isn’t worth the money, we’ll tell you.

Thermostat Repair & Smart Upgrades in McLean

Thermostat trouble is one of the most searched HVAC problems in McLean — and the one homeowners misdiagnose most. A “dead” system is often a thermostat issue: corroded wiring in older two-wire setups, a smart thermostat that lost compatibility after a DIY install, or a zoning panel in a teardown-rebuild custom that was never configured properly.

We repair thermostats in McLean — Nest, ecobee, and other smart models — and we’ll tell you honestly whether your wiring supports the upgrade; many older homes need a common wire added or a zoning board tuned first.

Furnace & Heater Repair in McLean

Furnace repair in McLean, VA spikes in the first real cold snap of November, when systems that sat idle all summer are asked to fire for the first time. The symptoms we hear most: the furnace won’t start, it blows cold or lukewarm air, it short-cycles every few minutes, or it’s making grinding or banging noises.

Many McLean homes run two furnaces — one per floor — so a “no heat” call can mean one failed while the other is fine. We check both, plus the heat exchanger, flame sensor, igniter, and blower. If your system is past its useful life, we’ll walk you through the repair-vs-replace math instead of pushing a sale. Call (703) 782-5028 for same-day McLean furnace repair.

Heat Pump Repair, Replacement & Installation in McLean

Heat pump installation in McLean is one of our fastest-growing calls (90 monthly searches at just 4% keyword difficulty). A modern cold-climate heat pump handles most of a Northern Virginia winter, with the gas furnace as backup on the coldest nights — the dual-fuel setup we install in many larger Fairfax County homes.

We repair all makes and models; when replacement beats another repair, heat pump replacement in McLean runs $5,500–$18,500 depending on tonnage, efficiency, and ductwork. Financing is available — we’ll show you the monthly payment before you decide. More on our heat pump installation in McLean page.

AC Installation & Heating Replacement in McLean

AC installation in McLean isn’t about picking a bigger box. In a market where homes are routinely torn down and rebuilt larger, the load calculation matters more than anywhere else in Fairfax County. We run a Manual J on every installation so the system matches the home you have — not the one that used to stand on the lot.

That matters for heating replacement in McLean: many 1960s colonials still run their first or second furnace, and when a home is rebuilt around it, the old system can’t keep up. An AC replacement — or full AC-and-furnace combo ($6,000–$18,000) — is also the moment to get zoning right. If another contractor quoted you, bring us the quote: our free second opinion has saved McLean homeowners from oversized equipment more than once. See AC installation in McLean for options.

McLean's Teardown-Rebuild Reality: Why We Check HVAC Age First

Walk through Franklin Park or older Chesterbrook and you’ll see 1960s split-levels and ramblers — originals — next to brand-new 10,000-square-foot customs on the same street. McLean’s teardown-rebuild cycle is relentless: buyers pay land value, scrape the lot, and build bigger.

So the first thing we check in a McLean home is equipment age. Fairfax County buyers and inspectors flag aging HVAC during the sale of mid-century homes, and a 20-year-old furnace in a home headed for renovation is a different decision than the same furnace in one you’re keeping. We size for the new envelope when a rebuild is planned, don’t oversell on homes that will be scraped in two years, and document system condition in plain language that helps at inspection. We’ve watched this cycle since 1999 — and no other HVAC company serving McLean builds the estimate around what happens to the lot next.

Duct Cleaning in McLean

With McLean’s constant construction — teardowns next door, additions, full renovations — duct cleaning earns its keep here. Fine drywall dust reaches supply runs even when your home wasn’t the one being remodeled, and 1960s ductwork can carry decades of debris no filter catches.

We recommend duct cleaning after nearby construction, after a system replacement, or when airflow has quietly worsened room by room. Our duct cleaning in McLean techs inspect first and clean only what’s needed.

What HVAC Service Costs in McLean

Most HVAC repairs in McLean run $149–$2,300, diagnostics $89–$249, and full replacements $5,500–$18,500 (heat pump) or $6,000–$18,000 (AC + furnace). What moves a job within those bands:

Job	Typical McLean range	What pushes it up
Diagnostic visit	$89–$249	After-hours emergency call
Common AC/furnace repair	$149–$2,300	Compressor, heat exchanger, multi-zone controls
Heat pump installation	$5,500–$18,500	Tonnage, efficiency rating, ductwork changes
AC + furnace replacement	$6,000–$18,000	Zoning, custom-home square footage

McLean tickets run larger than average because the homes are larger, so financing math belongs in the conversation: a $12,000 system on a 60-month plan is roughly $200 a month depending on approved terms. Oversized quotes are common on big homes; our free second opinion exists so you never sign one.

Free Second Opinion Before You Replace

Replacement quotes on large McLean systems are the easiest place in HVAC to overspend — on tonnage you don’t need, efficiency tiers that never pay back, or a full replacement when a targeted repair would buy five more years. If another company told you your system is done, call (703) 782-5028 before you sign. We’ll inspect and give you our honest read. The second opinion is free.

Frequently Asked Questions About AC & Heating Repair in McLean

How much does HVAC repair cost in McLean, VA?

Most repairs run $149–$2,300; diagnostics $89–$249. McLean tickets skew higher because the homes and systems are larger. Full replacements: $5,500–$18,500 (heat pump), $6,000–$18,000 (AC + furnace). Financing is available, and our free second opinion means you never pay for a replacement you didn’t need.

Do you provide emergency HVAC services in McLean?

Yes — 24/7 emergency HVAC repair across all of McLean, dispatched from our Vienna shop minutes away. Call (703) 782-5028 any hour: we triage by phone first (some emergencies are a tripped breaker), then dispatch with upfront pricing. No-heat calls in winter and AC failures in summer get priority.

Can you fix my furnace today?

Usually, yes. Our trucks carry the parts that fail most — igniters, flame sensors, capacitors, blower motors — and most McLean neighborhoods are a short drive from Vienna. Call before noon for a same-afternoon visit. If a part isn’t in stock, we stabilize the system and return, typically within 24 hours.

Should I repair or replace my AC?

Use the 50% rule: if the repair costs more than half of a new system and your AC is over 12–15 years old, replace. In McLean, ask what happens to the lot — if a teardown or renovation is planned, a targeted repair that buys a few years often beats a premium system sized for a home that won’t exist much longer.

Do you repair thermostats in McLean?

Yes — thermostat repair is one of our most common McLean calls. We fix wiring issues, compatibility problems after DIY smart-thermostat installs, and misconfigured zoning panels. We install Nest, ecobee, and other smart thermostats, and verify your wiring supports the upgrade before you buy.

What McLean neighborhoods do you serve?

All of them: Langley Forest, Langley Farms, Franklin Park, Chesterbrook, Chesterbrook Woods, Salona Village, Evans Farm, Potomac Hills, and West McLean — across ZIPs 22101, 22102, and 22106.
