Looking for an HVAC company in Falls Church? The Little City mixes 1940s cottages with brand-new custom builds, often on the same block, and each needs a different kind of HVAC company. We're both, and we've serviced Falls Church for decades.
Why us?
Serving Falls Church
Falls Church may be Northern Virginia's most concentrated teardown market: original 1940s and 50s cottages and ramblers in Broadmont and Greenway Downs sit next to 5,000-square-foot custom builds that replaced their neighbors. For an HVAC company that means two completely different practices on one street, keeping a 70-year-old home's retrofitted systems alive, and servicing the multi-zone, high-efficiency equipment the new builds run.
The older homes bring classic problems: retrofit ducts that starve back rooms, boilers and early furnaces due for honest end-of-life advice, and panels that predate everything. The new customs bring their own, builder-installed zoning that never got balanced, humidifiers nobody commissioned, and warranty maintenance that has to be documented from year one.
The Little City sits right in our daily loop, and cottage or custom, every visit counts toward the same scoreboard: a 4.9-star average built across 1,300+ Google reviews. We keep it the boring way, honest calls on repair versus replace, and help the same day when a system quits mid-heat-wave.
Our Services
AC repair, heating, heat pumps, and ductless for Broadmont, Winter Hill, and the city core.
Falls Church AC calls split by era: retrofit systems in the 40s and 50s cottages failing from age and awkward installs, and near-new equipment in the custom builds failing from commissioning shortcuts, unbalanced zones, sloppy charge, kinked flex duct. We diagnose per-house, not per-formula, and fix most of it the same visit.
From original boilers in Broadmont cottages to two-stage furnaces in the new builds, we repair every heating system Falls Church runs, the same day. We're also one of the last companies servicing oil heat, which still warms a few of the Little City's oldest homes.
In an original Falls Church cottage, replacement is a chance to fix decades of retrofit compromises; in a newer custom, it's about matching the multi-zone design the house was built around. Either way we size with a real load calculation, quote free, and offer 0% financing options with next-day installs on most systems.
The Little City's cottages, attic offices, and detached studios are ideal ductless candidates, and even the big new builds use mini-splits for bonus spaces the main zones don't reach. As a Mitsubishi Diamond Contractor we install quiet single- and multi-zone systems that fit both eras.
Falls Church leans green, and heat pumps are the centerpiece: cold-climate inverter systems replacing gas pairs in renovations, and ductless hybrids in the older stock. We repair every brand and install high-efficiency units sized for how each house is actually built and insulated.
Falls Church's mature canopy loads condensers with pollen and leaf litter, and the new builds' warranties demand documented annual service. Our tune-ups handle both ends, cleaned coils, checked refrigerant and electrical, kept records, with priority scheduling for maintenance plan members.

Reviews
Real reviews from real Leonard Splaine jobs across Falls Church 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, and often on the same street. The 1940s cottages need retrofit expertise and honest end-of-life advice; the new customs need zoning balance and documented warranty maintenance. We do both every week in Falls Church.
It's common, builder zoning often ships unbalanced, but it's fixable. We test and balance the zones, correct dampers and airflow, and get the system performing the way the house was designed to.
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.
