Looking for an HVAC company in Lorton? Lorton flipped from prison town to boom town in twenty years, and its housing shows it: Laurel Hill and Lorton Station new-builds next to Route 1 originals. We service both, ten minutes up I-95 from our Woodbridge shop.
Why us?
Serving Lorton
Few places in Fairfax County changed as fast as Lorton. After the old DC prison closed, Laurel Hill, Lorton Station, and Spring Hill filled with 2000s-era single-families and townhomes, while the streets off Route 1 and near Gunston kept their older, modest homes. Ten minutes up I-95 from our shop, we've serviced Lorton through the whole transformation.
The newer neighborhoods are entering their first real replacement cycle: builder-grade systems from the early 2000s hitting 15-20 years, water heaters failing in finished basements, and warranties that lapsed because nobody kept maintenance records. The older Route 1 homes need honest repair-or-replace judgment on equipment that's earned retirement, and some still run oil heat we're one of the last to service.
Seventy years in, we're still the family company we started as, and we're close enough to Lorton that same-day means exactly that. Call us at 2am and a real person picks up; call at 2pm and odds are a truck is already on I-95 headed your way.
Our Services
AC repair, heating, heat pumps, and oil heat, from Laurel Hill new-builds to Gunston originals.
Lorton's 2000s systems are failing on schedule, and we're ten minutes away when yours does. In Lorton Station and Laurel Hill it's usually capacitors, condenser fan motors, and coils leaking at the seams; in the older Route 1 homes it's equipment at true end-of-life. Same-day response, flat-rate pricing, honest repair-or-replace advice.
We repair every heating system Lorton runs: the gas furnaces in the newer subdivisions, heat pumps in the townhomes, and the older oil furnaces still working along Route 1 and near Gunston, which we're one of the last companies to service and fuel. No heat calls get priority all winter.
First-time replacements are Lorton's story right now, the builder systems in Laurel Hill and Lorton Station are aging out together. We replace them with properly load-calculated equipment instead of cloning the builder's spec, the replacement estimate is free, and seniors and military save 5%.
Finished basements in the newer sections, sunrooms and additions in the older ones, and the odd converted outbuilding near Gunston, Lorton has plenty of spaces central air doesn't reach well. As a Mitsubishi Diamond Contractor we fit quiet ductless heads that give those rooms their own comfort.
Lorton's townhomes run heavily on heat pumps, and the originals are due. We repair every brand and replace end-of-life units with high-efficiency inverter systems, plus dual-fuel combos for the single-families that want gas backup on the coldest nights.
If your Lorton home still has its original 2000s system, maintenance is what decides whether it lasts 15 years or 20. Our tune-ups clean coils, check refrigerant and electrical, clear drains, and keep the documentation that protects any remaining warranty. Plan members get priority scheduling and 15% off repairs.
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 Lorton 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.
You're in the window. Builder-grade systems from that era typically last 15-20 years, and Laurel Hill and Lorton Station are hitting it now. A tune-up tells us honestly how much life yours has left, and a free estimate prices the replacement before it's an emergency.
Yes. We're one of the last companies in the region that services oil furnaces and boilers and delivers heating oil, and Lorton's older homes are a regular part of that route.
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. Approve a repair over $250 on the same visit and the $89 comes off your bill, whether or not you are a member. Maintenance members have the fee waived on any repair they approve, with no minimum. 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.
