Looking for an HVAC company in McLean? McLean homes run three and four HVAC zones, wine cellars, pool houses, and estates where a single failed system can mean thousands of square feet gone uncomfortable. We service them with the discretion and precision the neighborhood expects.
Why us?
Serving McLean
McLean's housing stock is large, complex, and mechanical-heavy: multi-zone systems on every floor, dedicated equipment for wine storage and pool houses, whole-home humidification, and generators as standard equipment. When something fails in a Langley or Chesterbrook home, the question isn't just what broke, it's which of four systems, and whether the others are compensating quietly.
This scale rewards a company that documents everything. We map each home's systems on the first visit, zone by zone, so the next call starts with knowledge instead of exploration. And because plenty of McLean homes also include an original 1950s wing or a guest cottage, the old-house skills matter here too, boilers, retrofits, and ductless where ducts never went.
Discretion and documentation come standard in McLean, and so do our regular terms: real quotes in writing, an $89 diagnostic waived for maintenance members, and certified employees on every visit. We've worked these streets for decades, quietly, which is exactly how the neighborhood prefers it.
Our Services
Multi-zone systems, boilers, ductless, and specialty-space HVAC for Langley, Chesterbrook, and beyond.
In a McLean home with three or four cooling zones, a failure can hide, one system limps while another compensates, until a heat wave exposes it. We diagnose per-zone across Langley, Chesterbrook, and Salona Village, repair every brand including the high-end variable-speed equipment common here, and document what we find for next time.
McLean heating plants range from multiple high-efficiency furnaces to boilers running radiant floors and estate wings. We repair all of it the same day, and we're one of the last companies that services boilers and hydronic systems properly, which matters in the neighborhood's older and finest homes.
Replacing equipment in a multi-zone McLean home is a systems job: matching capacity per zone, integrating controls, and staging the work so the house never goes fully down. We run real load calculations per zone, offer free estimates, and coordinate cleanly with housekeepers, contractors, and schedules.
Pool houses, guest cottages, garden studios, gyms, and wine rooms, McLean's outbuildings and specialty spaces run on ductless, and we install a lot of it. As a Mitsubishi Diamond Contractor we fit precise, near-silent systems, including temperature-critical applications like wine storage.
High-efficiency inverter heat pumps are replacing older equipment across McLean, quieter, steadier, and cheaper to run at scale. We repair every brand and design multi-zone and dual-fuel configurations that fit homes where comfort expectations are absolute.
Four systems mean four maintenance schedules, and McLean homes can't afford the entropy. Our maintenance plan puts the whole estate on one calendar, every zone tuned seasonally, filters and humidifiers serviced, documentation kept, with priority scheduling when anything does fail.
Brands
We repair every major brand and install new systems from the best of them. We're a Lennox Premier Dealer and a Mitsubishi Electric Diamond Contractor.

Reviews
Real reviews from real Leonard Splaine jobs across McLean and Northern Virginia, from same-day AC repairs to full system installs. We've earned our 4.9-star average the slow way: answering the phone, showing up on time, and doing right by every home.
Lynn Gilbertson Google review Kyle provided emergency holiday weekend service when our a/c was completely out with 104F "feels like" temperatures. He quickly diagnosed and fixed our system, with solutions for avoiding similar problems in the future. We are grateful to Kyle and Leonard Splaine!
Katie Kada Facebook recommendation Couldn't have asked for better service! Leonard Splaine was timely, honest and did a wonderful job replacing our very outdated AC unit. We plan to use them again for any service or replacement in the future and we'll recommend them to our friends and family.
I will definitely use this company again! Our AC went out on one of the hottest days of the year. They answered and came to the rescue! Family owned and very kind. Technician was knowledgeable and quick.
Ankur Mundra Facebook recommendation I've used Leonard Splaine the last 5 years. They are professional, provide quality service, and answer my questions and concerns. Michael Ford came out this year to do my spring maintenance as well as eztrap installation and condenser coil cleaning. He did an excellent job.
Candace Bond Google review They were such gentlemen and seemed to be very knowledgeable and honest. They were also very patient and took the time to answer all of our questions. I would highly recommend these guys.
A/C stopped working on the hottest day of the year, so far. They came over the same day and had it up and running in no time. The price was reasonable and the tech was great.

Good questions
The things homeowners ask us most. Anything else, the phone's faster than the internet.
Yes, on one plan and one calendar. We map every zone and system on the first visit, tune each seasonally, and keep the documentation, so any tech we send arrives already knowing your house.
Yes. Specialty spaces are routine work for us in McLean, precise ductless and dedicated systems for wine storage, pool houses, gyms, and guest cottages, installed and serviced quietly.
In most cases, yes. We run a large fleet out of Woodbridge and hold room in the schedule for same-day repair calls across Northern Virginia. Call before noon and we can almost always be there the same day. Earlier in the day is better during peak season.
For residential HVAC, our diagnostic fee is $89. It covers a real diagnosis and a straight, written price before any work starts. Maintenance members have the diagnostic fee waived when they proceed with the repair. Ask us about the membership. Replacement estimates for HVAC systems, water heaters, electrical panels, and EV chargers are always free.
Yes. We work with multiple financing partners and pass along manufacturer promotions as they run, including 0% and low-monthly-payment options on new systems. Tell us your budget and we'll build options around it.
All of them. Our technicians repair every major brand of furnace, heat pump, AC, boiler, and water heater. For new installations we're a Lennox Premier Dealer and a Mitsubishi Diamond Contractor, including ductless mini-splits, and we also specialize in Carrier.
We do. We're one of the last companies in Northern Virginia that both services oil heating systems and delivers home heating oil and off-road diesel. If you have an oil furnace or boiler, you only need one phone number.
Yes. Alongside heating and cooling we install air filtration, whole-home humidifiers, UV purification, and air purifiers, a big help during Northern Virginia's pollen seasons and dry winters. Ask about it during any air conditioner or furnace visit, or book an air quality assessment on its own.
Yes, and it matters. Leonard Splaine has been owned and run by the same family for three generations, since 1956. We haven't been bought by private equity, and we're not going to be. When you call us, you're dealing with people whose name is on the trucks.
Same-day service across Northern Virginia. Talk to a real person, day or night.
