Looking for an HVAC company in Garrisonville? Garrisonville is Stafford's commuter engine, subdivisions off Route 610 filled with early-commute households whose HVAC has to work around 5am departures and evening returns. We schedule like we mean it, from just up I-95.
Why us?
Serving Garrisonville
Garrisonville grew along Route 610 as the southern anchor of the I-95 commute: 80s, 90s, and 2000s subdivisions like Shadow Woods and Oakridge Estates, townhome communities near the commuter lots, and newer construction filling the gaps toward Rock Hill. It's a working community with brutal schedules, and home systems that get noticed only when they fail.
The equipment story is generational like the rest of the corridor: 90s systems aging out street by street, townhome heat pumps running hard on three levels, and newer builds needing documented warranty maintenance. What's distinct here is the scheduling, slug-lot commuters and Quantico families need appointment windows that respect a household that leaves before dawn.
A household that leaves before dawn can't sit around waiting on a contractor, so we quote flat-rate before any work starts and hit the window we promised. Garrisonville is a straight shot down I-95 from our shop, and when you call, day or night, a live person answers.
Our Services
AC repair, heating, heat pumps, and ductless along the Route 610 corridor.
When a Garrisonville AC dies, the household usually discovers it at 6pm after a commute, and we plan for that: same-day and evening-friendly response along the Route 610 corridor. The 90s-era systems in Shadow Woods and Oakridge fail predictably, capacitors, fan motors, leaking coils, and we carry the parts to fix most of it first-visit.
Garrisonville heats with gas furnaces in the subdivisions and heat pumps in the townhomes, and we repair both the same day, no heat, short-cycling, failed igniters, bad blowers. Quantico families rotating in and out get the same straight treatment as thirty-year residents: honest diagnosis, flat-rate price, no games.
The 90s streets off Route 610 are replacing systems in waves now. We size each home individually, real load calculation, finished basement and bonus room counted, and we schedule installs around commuter reality, with free estimates, 0% financing options, and next-day turnaround on most systems.
Garrisonville's bonus rooms, garage gyms, and finished basements, plus the townhome top floors that bake all summer, are ductless problems with ductless answers. As a Mitsubishi Diamond Contractor we install quiet single-zone heads and multi-zone systems that fix the specific room.
The townhome communities near the commuter lots run heat pumps year-round, and that duty cycle ages them fast. We repair every brand and replace end-of-life units with high-efficiency inverter systems that hold the top floor, plus dual-fuel setups in the single-family sections that kept gas.
For households that leave before dawn, a mid-July breakdown is a scheduling disaster, and maintenance is the cheap way out. Our tune-ups catch the weak capacitor in April, keep warranty documentation current on the newer builds, and plan members get priority scheduling and waived diagnostics.
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 Garrisonville 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, it's half of Garrisonville. We offer firm windows, call-ahead notice so you can time the drive, and same-day slots that respect a household that leaves before dawn and gets home at six.
Every week. We know the three-level heat pump setups, the tight utility closets, and the top-floor heat complaints, and we stock for the common floor plans.
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.
