Looking for an HVAC company in Woodbridge? From the historic streets of Occoquan to the newer subdivisions off Prince William Parkway, Leonard Splaine has kept Woodbridge homes comfortable since 1956, and our shop is right here on Occoquan Road.
Why us?
Serving Woodbridge
Woodbridge is home for us. Our shop sits on Occoquan Road, minutes from Potomac Mills and the Occoquan River, and our trucks work Lake Ridge, Dale City, Marumsco, and the rest of eastern Prince William County every day. We know these homes: the split-levels and colonials built through the 70s and 80s that are on their second or third HVAC system, the townhomes packed along Route 1, and the newer builds out toward Prince William Parkway.
Being this close matters when your AC dies in July or your heat quits in January. We're not dispatching a truck from an hour away, we're already in the neighborhood, and a real person answers day or night. After 70 years and three generations, we've never been sold to private equity, and it shows in the work: a 4.9-star average, straight prices, and an $89 diagnostic that's waived for maintenance members.
Homes near the Occoquan and Neabsco Creek can sit low and damp, which is hard on outdoor units and a good reason plenty of Woodbridge families add a standby generator or a sump-pump circuit. One local call covers all of it: cooling, heating, water heaters, electrical, and generators, handled by certified employees we trained.
Our Services
AC repair, installation, heating, heat pumps, and ductless, handled by the crew whose shop is five minutes away.
When the humidity rolls in off the Occoquan and your AC gives out, we run same-day repairs across Woodbridge, Lake Ridge, and Dale City. Our techs handle the failures we see most in this area's 70s-and-80s housing stock: tired compressors and capacitors, refrigerant leaks in aging line sets, frozen coils, and condensate drains that back up in our sticky Prince William summers. Straight diagnosis, flat-rate pricing, most fixed the same visit.
Woodbridge winters swing from mild to bitter, and a furnace that quits at 6am doesn't wait. We repair gas and electric furnaces, heat pumps, and boilers across eastern Prince William, and we're one of the last companies around here that still services oil heat and delivers home heating oil, which plenty of older homes near Occoquan still run on. No heat, short-cycling, bad igniters, cracked heat exchangers, we find it and fix it.
A lot of Woodbridge homes are on their second or third AC, and a builder-grade unit in a Lake Ridge colonial is rarely sized right for the additions and finished basements added since. We install and replace central air with a real load calculation, not a guess, and as a Lennox Premier Dealer we back it with free estimates, 0% financing, and next-day installs on most systems.
The older homes near the Occoquan River and the converted garages and sunrooms all over Woodbridge are perfect candidates for ductless mini-splits, especially the ones with no ductwork or a room that's always too hot. As a Mitsubishi Diamond Contractor we design single- and multi-zone systems that heat and cool quietly without tearing into plaster walls.
Heat pumps are a great fit for Woodbridge's mild-winter, hot-summer climate, and they carry a home year-round on one efficient system. We repair every brand and install high-efficiency and dual-fuel heat pumps, with the dual-fuel setup handing off to gas heat on those few truly cold Prince William nights, so your bills stay down without you ever losing heat.
The dust and pollen that blow through Woodbridge every spring clog coils and filters fast, and our humid summers push tired parts over the edge. A spring tune-up clears the coils, checks refrigerant, and catches a weak capacitor in April instead of during a July heat wave. Ask about our maintenance plan for priority scheduling and waived diagnostics.

Reviews
Real reviews from real Leonard Splaine jobs across Woodbridge 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. Our shop and office are on Occoquan Road in Woodbridge, and it has been our home base since 1956. When you call, you reach our local office, and our trucks are already working Woodbridge, Lake Ridge, and Dale City every day.
We do. Plenty of older homes near Occoquan and along Route 1 still heat with oil, and we are one of the last companies in the area that both services oil systems and delivers home heating oil and off-road diesel.
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.
