Looking for an HVAC company in Stafford? Stafford's commuter subdivisions from the 90s boom through Embrey Mill's newest streets all run hard-working HVAC, and some of the county still runs on wells and propane. We cover it all, straight down I-95 from Woodbridge.
Why us?
Serving Stafford
Stafford County grew in waves down the I-95 corridor: Park Ridge and Hampton Oaks in the late 80s and 90s, Austin Ridge through the 2000s, and Embrey Mill still building today. Add the established homes near Quantico and the rural properties west of the interstate, and you get a county that spans brand-new builder systems, 25-year-old equipment due for honest replacement talks, and homes running propane and well water.
The 90s subdivisions are Stafford's biggest HVAC story right now: original and first-replacement systems aging out street by street, water heaters failing in finished basements, and panels full just as everyone wants an EV charger for the commute. The newer sections need warranty-documented maintenance and fixes for builder shortcuts; the rural properties need techs comfortable with propane furnaces and well-pressure quirks.
After 70 years we've never sold to private equity, and Stafford gets the full benefit of that: an easy run down I-95 means a same-day call gets a same-day truck, and the person diagnosing your system is our own employee quoting a price you can hold us to.
Our Services
AC repair, heating, heat pumps, and propane systems down the I-95 corridor.
Stafford's 90s-era systems in Park Ridge and Hampton Oaks are failing on schedule, capacitors, condenser fan motors, leaking coils, while Embrey Mill's newer equipment mostly needs commissioning fixes and warranty work. We run same-day repairs down the I-95 corridor with flat-rate pricing and honest repair-or-replace advice.
Stafford heats with gas furnaces in the subdivisions, heat pumps in the townhomes, and propane out where the gas lines don't reach, and we repair all of it the same day. No-heat calls get priority all winter, and the rural properties west of I-95 are as routine for us as the cul-de-sacs.
Whole Stafford streets built in the same 90s summer are replacing systems together now. We size each home individually with a real load calculation, finished basement and bonus room included, instead of cloning the builder spec. Estimates are free, financing is available, and Quantico families save 5% with our military discount.
Stafford's bonus rooms over garages, finished basements, and detached workshops, common on the county's larger lots, are exactly what ductless solves. As a Mitsubishi Diamond Contractor we install quiet single- and multi-zone systems that give those spaces their own comfort without touching the main ductwork.
Heat pumps carry a big share of Stafford, especially the townhome communities, and dual-fuel setups make sense where propane backup beats resistance heat. We repair every brand and install high-efficiency inverter systems that handle the county's full seasonal swing.
A 90s-era Stafford system on its last legs needs maintenance to see another summer, and Embrey Mill's warranties require documented service to stay valid. Our tune-ups cover both, cleaned coils, checked refrigerant and electrical, kept records, with priority scheduling for plan members.

Reviews
Real reviews from real Leonard Splaine jobs across Stafford 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. Plenty of Stafford west of I-95 runs both, and we service propane furnaces, size generators to carry well pumps, and account for well water in water-heater work.
You're in the window, and yes, we see Stafford streets replace in waves. A tune-up tells you honestly where your system stands, and pricing the replacement before it's an emergency beats doing it during a heat wave.
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.
