Looking for furnace repair in Northern Virginia? Leonard Splaine runs same-day, no-heat furnace repair on gas and electric furnaces, every brand, with a straight diagnosis, upfront pricing, and most repairs done the same visit.
Why us?
Serving Northern Virginia
When the furnace quits on a cold night, our certified techs find and fix it fast. We handle every common failure: no heat at all, a furnace that short-cycles or won't ignite, a bad igniter or flame sensor, a failed blower or inducer motor, a cracked heat exchanger, a stuck gas valve, weak airflow from dirty filters or ductwork, and control boards and thermostats that lost their signal. A well-running furnace also burns more efficiently and lasts longer, so a timely repair protects both your energy bills and the system's lifespan. You get a straight diagnosis and upfront pricing before any work starts, and most repairs are finished the same visit.
Winter no-heat calls are where an HVAC company shows its character, and ours has been on display in Northern Virginia through three generations of one family. The playbook hasn't changed in 70 years: diagnose honestly, put the price in front of you before a wrench comes out, and keep a flat $89 diagnostic that's waived for maintenance members.
Wake up to a cold house and call us: our phones are staffed around the clock, and no-heat repairs get first claim on each day's schedule, so a certified tech is usually at your door before the day is out.
Our Services
The most common furnace failures we fix same-day across Northern Virginia, on every brand.
No heat on the coldest night is our top priority. We diagnose why the furnace quit, whether it's a tripped safety, a failed part, a bad thermostat signal, or a furnace that short-cycles and never warms the house, and fix it the same visit whenever we can.
A furnace that clicks but won't light is usually the ignition system. We replace cracked hot-surface igniters, clean or replace dirty flame sensors, and fix the ignition control so the burners light reliably instead of locking out on you.
If the furnace fires but no warm air moves, or you hear grinding and rattling, it's usually a motor. We repair and replace blower motors, inducer draft motors, and the run capacitors and control boards behind them, so the furnace moves heat the way it should.
A cracked heat exchanger is a carbon monoxide risk, not just a comfort problem. We inspect the heat exchanger, test for cracks, and give you a straight answer on whether it's safe to run, repairable, or time to replace, never a scare tactic.
Weak, uneven, or yellow flames and a furnace that won't stay lit usually trace to the gas valve, burners, or pilot. We clean and adjust burners, replace faulty gas valves, and get the flame burning clean and blue again for safe, efficient heat.
When the furnace acts random, dead one minute and running the next, it's often the control board or wiring. We test the board, limit switches, transformer, and connections, and replace what's failing so the furnace runs on a signal it can trust.

Our certified techs repair every major brand of gas and electric furnace, from Lennox and Carrier to Trane, Goodman, Rheem, and beyond.

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 questions Northern Virginia homeowners ask us most about furnace repair. Anything else, the phone's faster than the internet.
Common causes are a tripped safety switch, a bad igniter or flame sensor, a failed blower or inducer motor, a thermostat that lost its signal, or a clogged filter shutting the furnace down on a limit. Our techs find the real cause on the first visit instead of guessing at parts.
In most cases, yes. We hold same-day slots for no-heat calls all winter across Northern Virginia, and a real person answers day or night.
It can be, because a crack can let carbon monoxide into your air. If we find one, we show you, explain the risk honestly, and lay out your options, repair versus replacement, without pressure or scare tactics.
It depends on the part and the problem, but you'll always get an upfront price before we start. Our diagnostic is a flat $89, waived for maintenance members.
If your furnace is under 15 years old and the fix is minor, repair it. Older than that, or facing a cracked heat exchanger or a failed inducer, replacement is often the smarter money. We give you the honest numbers and a free replacement estimate either way.
