Looking for an HVAC company in Ballston? Ballston stacks glassy condo towers on top of 1940s brick neighborhoods, and the two need completely different HVAC answers. We service both sides of the block, and the HOA paperwork doesn't scare us.
Why us?
Serving Ballston
Ballston is two housing markets sharing a metro stop at the west end of the Rosslyn-Ballston corridor. Along Wilson and Fairfax Drive it's high-rise and mid-rise condos, most running water-source heat pumps or compact fan-coil units in closets the size of a phone booth. A block or two out, in Ashton Heights, Bluemont, and Buckingham, it's brick colonials and garden apartments from the 30s and 40s, plenty still heated by radiators with no ductwork at all.
Condo work here means units that fail on the hottest Friday of the year, buildings with rules about when and how contractors work, and equipment that has to come through a lobby and up a service elevator. We've done it for years: we bring the certificate of insurance the building manager asks for, protect the floors, and get the old unit out and the new one running without drama.
In the older blocks the work looks like the rest of Arlington: ductless mini-splits that cool without touching plaster, boilers kept alive by people who still know how, and panel upgrades for houses whose wiring predates half the appliances plugged into it. The same crews cover the whole corridor, from Rosslyn down through Lyon Village to Pentagon City and Shirlington, for households commuting into Washington, DC every day. One number covers all of it, and a real person answers it day or night.
Our Services
Condo heat pumps, ductless retrofits, boilers, and panel upgrades from the corridor to Bluemont.
Ballston AC failures split by building age: condo heat pumps and fan-coils that quit in a closet on the 9th floor, and retrofitted systems in Ashton Heights colonials sweating through August. We repair both same-day, and we handle the building-access dance, COIs, elevator reservations, quiet hours, without you chasing paperwork.
Heating in Ballston runs from building-supplied loops and electric heat pumps in the towers to gas furnaces and original radiators in the side streets. No heat in a condo is usually a failed compressor or valve; in a 1938 colonial it's often the boiler. We diagnose honestly and fix both the same day.
Replacing a condo unit in Ballston means matching the building's riser, water loop, or electrical spec, and getting it approved. Replacing a system in Bluemont means designing around plaster and framing. We've done both enough times to quote accurately the first visit, with free estimates and 0% financing options.
Mini-splits solve Ballston's two hardest rooms: the radiator-heated colonial with no ducts, and the condo den the building system never quite reaches. As a Mitsubishi Diamond Contractor we install low-profile heads sized for the space, with condenser placement that keeps HOAs and next-door neighbors happy.
Half of Ballston already heats and cools with heat pumps, they just live in closets and on roofs instead of side yards. We repair every brand of condo water-source and split-system heat pump, and we install cold-climate inverter units that hold output through January for the houses making the electrification jump.
Condo fan-coils choke on lint and dust; closet filters get forgotten for years; corridor-house condensers eat street grit. Sealed condo air also concentrates humidity and indoor air quality problems that a clean coil and fresh filtration mostly solve. A yearly tune-up catches all of it before the July failure, and maintenance plan members get priority scheduling and waived diagnostics.

Reviews
Real reviews from real Leonard Splaine jobs across Ballston 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, routinely. We send the certificate of insurance your management company asks for, book the service elevator, and work within quiet hours. Tell us the building when you call and we'll have the paperwork moving before the visit.
Almost always. Most Ballston buildings run standard water-source or split-system equipment behind a custom closet door. We match the spec, coordinate approval with management, and swap it with minimal downtime.
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.
