Looking for an HVAC company in Aquia Harbour? Aquia Harbour's gated, wooded streets along Aquia Creek have their own rhythms, private roads, marina moisture, and 70s-and-80s homes deep in the trees, and we've serviced them for years from just up I-95.
Why us?
Serving Aquia Harbour
Aquia Harbour is one of a kind in our service area: a gated community of 1970s and 80s homes wound through heavy woods along Aquia Creek, with a marina, a golf course, and private roads patrolled by its own police. The setting is the point, and it's also the HVAC story: deep shade, constant leaf load, creekside humidity, and homes now on their second or third systems.
Wooded, water-adjacent lots are hard on equipment. Condensers live under year-round organic fall, crawl spaces run damp enough to rust ductwork from below, and the humidity off the creek makes dehumidification part of real comfort here, not an add-on. Add the community's aging original equipment, and honest repair-or-replace judgment matters more than anywhere.
Service inside the Harbour starts with knowing the gate, and our techs do, along with the winding streets behind it. We're a short run down I-95, family-owned for three generations, and same-day applies behind the gate like everywhere else, whether the call is a heat pump, a water heater, or the standby generator half the neighborhood runs.
Our Services
AC repair, heating, heat pumps, and ductless for the gated community along Aquia Creek.
Harbour AC units fight shade-side corrosion, leaf-packed coils, and creek humidity, and the community's 70s-and-80s systems are well into replacement age. We run same-day repairs inside the gate, our techs know the procedures, and we give straight advice when a repair is just delaying an inevitable replacement.
The Harbour heats with heat pumps and gas and propane furnaces, plus the occasional older oil system we're one of the last to service. Winter no-heat calls in the back sections get the same priority as anywhere, and we carry the common failure parts so one visit usually does it.
Replacing a system in Aquia Harbour means placing equipment for a wooded, damp site: condensers sited out of the heaviest leaf fall, pads set for drainage, and capacity sized for creekside humidity, not just square footage. Real load calculations, free estimates, 0% financing options, next-day installs on most systems.
Harbour homes love their sunrooms, screened porches being converted, and lower levels facing the creek, all spaces the original ductwork never conditioned well. As a Mitsubishi Diamond Contractor we install quiet ductless heads that give those rooms their own comfort, with the dehumidification the waterfront demands.
Heat pumps suit the Harbour's mild-winter woods, and most of the community runs them. We repair every brand, replace aging units with high-efficiency inverter systems that manage humidity far better than 80s technology, and set up dual-fuel where owners want propane backup.
Nowhere on our routes does maintenance matter more: Harbour condensers bury themselves in leaves and pollen every season, and damp crawl spaces quietly eat ductwork. Our tune-ups clean, inspect underneath, and catch the moisture problems early, with priority scheduling for plan members.

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 Aquia Harbour 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, we work in the Harbour regularly and know the gate and guest procedures. Have the gate expect us and we handle the rest, same-day service applies inside the community like anywhere else we serve.
Heavy shade, constant leaf and pollen fall, and creekside humidity are hard on condensers, ductwork, and electrical. Regular maintenance offsets most of it, which is why so many Harbour homes are on our plan.
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.
