Looking for an HVAC company in Springfield? Springfield's 1950s and 60s split-levels around Kings Park and North Springfield were built in the first wave of suburban AC, and plenty are still running systems several generations on. We service all of it, fifteen minutes up I-95 from our shop.
Why us?
Serving Springfield
Springfield is layered like tree rings: 1950s and 60s ramblers and split-levels in central and North Springfield, 70s and 80s colonials out in West Springfield and Rolling Valley, and the newer townhomes clustered toward the Franconia-Springfield Metro. Fifteen minutes up I-95 from our Woodbridge shop, it's been part of our daily routes for decades.
The older sections have classic mid-century problems: undersized ducts feeding split-level half-floors, panels that predate central AC entirely, and additions riding on systems that were maxed out to begin with. West Springfield's colonials are on second and third systems, and the commuter townhomes run heat pumps that work hard in both seasons. We know each layer's failure patterns because we've been fixing them since they were new.
Every tech we send to Springfield is a certified employee we trained ourselves, and the price we quote on Backlick Road is the same straight number we'd quote anywhere. One call handles the furnace, the AC, or the water heater, whichever layer of Springfield your house belongs to.
Our Services
AC repair, heating, heat pumps, and ductless, from Kings Park ramblers to Franconia townhomes.
Springfield AC calls skew toward age: original-era equipment in Kings Park and North Springfield, and second-generation systems in West Springfield hitting the 15-year wall. We're fifteen minutes up I-95, so same-day is standard, and our techs know the split-level airflow quirks that make an upstairs feel broken even when the compressor is fine.
From gas furnaces in the colonials to heat pumps in the Franconia townhomes, we repair Springfield heat the same day: no-heat calls, short-cycling, failed igniters and blowers, and the cracked heat exchangers that show up in furnaces past 15 winters. Older homes still on boilers or oil heat are welcome too, we're one of the last around that service both.
Replacing an AC in a 1960s Springfield split-level is a sizing job first and an install second: the original duct design starves the top floor, and cloning the old tonnage repeats the problem. We run real load calculations, fix airflow while we're in there, and back installs with free estimates, 0% financing options, and next-day turnaround on most systems.
Springfield's split-levels, basement in-law suites, and sunroom additions are ductless country. As a Mitsubishi Diamond Contractor we put quiet single-zone heads in the rooms central air never conquered, and multi-zone systems in homes where the ductwork isn't worth saving.
Heat pumps carry a huge share of Springfield's townhomes and an increasing share of its single-family replacements. We repair every brand, install high-efficiency inverter units that hold even temperatures through our muggy summers, and set up dual-fuel systems for owners keeping gas backup.
Springfield's older systems have less margin for neglect: a dirty coil or weak capacitor that a new unit shrugs off will drop a 15-year-old system on the first 95-degree day. Our tune-ups clean, test, and report straight, and maintenance plan members get priority scheduling and waived diagnostics.

Reviews
Real reviews from real Leonard Splaine jobs across Springfield 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, Kings Park, North Springfield, West Springfield, Rolling Valley, and the Franconia-Springfield corridor are all inside our daily service loop, fifteen minutes up I-95 from our shop.
Often, yes. Mid-century duct design starves upper floors and additions, and it's why so many Springfield split-levels feel uneven. We evaluate the ducts with every replacement quote and fix the airflow rather than just swapping the box.
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.
