Looking for heating service in Northern Virginia? Leonard Splaine repairs and replaces gas and electric furnaces, heat pumps, boilers, and oil heat, and a real person answers day or night. Family-owned since 1956.
Why us?
Serving Northern Virginia
A Northern Virginia winter swings from mild to bitter, and a furnace that quits at 6am doesn't wait. We repair gas and electric furnaces, heat pumps, and boilers, and we're one of the last companies in the region that still services oil heat and delivers home heating oil. One call covers all of it.
Heating is where our history runs deepest. This company has kept Northern Virginia homes warm through seventy winters, and the third generation of the founding family still signs off on how the work gets done: honest diagnosis first, a straight price second, and an $89 diagnostic that's waived for maintenance members.
No-heat calls get answered by a real person no matter when you dial, and they go to the front of the day's schedule. Furnace, heat pump, boiler, or oil burner, the tech who shows up is a certified employee.
Our Services
Furnace repair, heat pump service and installs, and one of the last oil-heat teams in Northern Virginia.
When the heat goes out in Northern Virginia, we're there the same day. We repair gas and electric furnaces, heat pumps, and boilers, and we're one of the last companies in Northern Virginia that still services oil heat and delivers home heating oil. No heat, short-cycling, bad igniters and blower motors, cracked heat exchangers, we find it and fix it right.
Heat pumps carry Northern Virginia homes through mild winters and hot summers, and they're one of the most efficient ways to stay comfortable in Northern Virginia year-round. We repair every brand and install high-efficiency and dual-fuel heat pumps, sized and set up to actually cut your energy bills rather than just replace what was there.
When repair no longer makes sense, we size and install a new gas or electric furnace with a real load calculation, not a guess. You get a free, itemized estimate and 0% financing options before anything is ordered.
A yearly tune-up catches small problems before they become a no-heat night and keeps your efficiency and warranty intact. Maintenance members get priority scheduling and a waived diagnostic fee.
No heat at 2am? A real person answers day or night, and same-day, no-heat calls go to the front of the schedule all winter. Furnace, heat pump, boiler, or oil burner, a certified tech gets you warm again fast.
Hot-water and steam boilers still heat plenty of older Northern Virginia homes, and we're one of the few companies that keep radiator and baseboard systems running. From leaking valves to full boiler replacements, we cover it.
We're one of the last companies in the region that both services oil heat and delivers home heating oil and off-road diesel. If you heat with oil, one phone number covers the burner and the fuel.
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 heating jobs across Northern Virginia. 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 questions Northern Virginia homeowners ask us most about heating. Anything else, the phone's faster than the internet.
Usually, yes. We keep room in the schedule for same-day, no-heat calls all winter across Northern Virginia. A real person answers day or night, and we run a large local fleet, so a truck is rarely far.
If your furnace is under 15 years old and the fix is minor, repair it. Past that, or facing a cracked heat exchanger or a failed inducer, replacement is often the smarter money. We show you the honest numbers and a free replacement estimate, never a scare tactic.
All of it. We repair and install gas and electric furnaces, heat pumps, and boilers, and we are one of the last companies in the region that still services oil heat and delivers home heating oil. One number covers every heating system in your home.
We do. Leonard Splaine both services oil furnaces and boilers and delivers home heating oil and off-road diesel across Northern Virginia. If you heat with oil, you only need one phone number.
It depends on the size, fuel, and efficiency your home needs, which is why we size every system with a real load calculation instead of a guess. We give you a free, itemized estimate and 0% financing options so there are no surprises.
