Looking for heat pump repair or installation in Northern Virginia? Leonard Splaine repairs every brand and installs high-efficiency and dual-fuel heat pumps that heat and cool your home year-round on one system.
Why us?
Serving Northern Virginia
Heat pumps carry Northern Virginia homes through mild winters and hot summers on a single system, and they're one of the most efficient ways to stay comfortable year-round. We repair every brand, no heat or no cool, weak airflow, a unit stuck in defrost, a bad reversing valve, a failed compressor or capacitor, or low refrigerant, and we install high-efficiency and dual-fuel heat pumps that lower your energy costs. Right-sizing matters, so we factor your ductwork and insulation into the load calculation instead of guessing from the old unit. When the temperature really drops, a dual-fuel setup hands off to a gas furnace so you're never cold.
Heat pumps demand more from a technician than a furnace or an AC, because one machine does both jobs. Our certified employees work on every brand, and carrying both Lennox Premier Dealer and Mitsubishi Diamond Contractor credentials means we install the equipment those manufacturers stand behind hardest. Seven decades in Northern Virginia taught us which systems actually survive our winters.
Whether your heat pump is stuck in defrost or you're weighing a dual-fuel upgrade, one call reaches a staffed phone at any hour. Repairs and free installation estimates alike usually land on that day's schedule.
Our Services
Repair, installation, and the parts that make a heat pump heat and cool efficiently all year.
No heat, no cool, or a unit stuck running in defrost, we diagnose it fast. Our techs fix every brand of heat pump: bad reversing valves, failed compressors and capacitors, low refrigerant from a leak, iced-up coils, and defrost controls that quit, so your system heats and cools the way it should.
We install high-efficiency heat pumps across Northern Virginia, sized to your home with a real load calculation and set up to actually cut your energy bills. One system heats and cools, and as a Lennox Premier Dealer we back it with free estimates and next-day installs on most systems.
The reversing valve is what lets a heat pump switch between heating and cooling, and the defrost cycle keeps the outdoor coil from icing up in winter. When either fails you get one mode but not the other, or a unit buried in ice. We diagnose and replace both.
A dual-fuel system pairs a heat pump with a gas furnace: the efficient heat pump does the work in mild weather, and when it gets truly cold the furnace takes over. We design and install these hybrid systems so you get low bills most of the year and never lose heat on the coldest nights.
A right-sized, well-maintained heat pump is one of the most efficient ways to stay comfortable in Northern Virginia, cooling in July and heating in January off the same equipment. We help you choose, size, and set up a system that keeps bills down all year instead of just replacing what was there.
A heat pump runs year-round, so it earns two tune-ups a year. Our maintenance plan covers scheduled service for heating and cooling, priority scheduling, waived diagnostics, and repair discounts, which keeps your heat pump efficient and your warranty valid. Ask us for the current details.

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 heat pump repair & installation. Anything else, the phone's faster than the internet.
Yes. Modern heat pumps stay efficient well into a Northern Virginia winter, and a dual-fuel setup adds a gas furnace that takes over on the coldest nights, so you get low bills most of the year without ever losing heat.
Common causes are a failed reversing valve, low refrigerant from a leak, a stuck defrost cycle, or a backup-heat problem. We diagnose the real cause on the first visit instead of guessing at parts.
It pairs a heat pump with a gas furnace. The heat pump handles heating and cooling efficiently in mild weather, and when it gets very cold the furnace takes over. You get the efficiency of a heat pump and the muscle of gas heat in one system.
If it's under 10 to 12 years old and the repair is minor, repair it. If it's older, low on R-22, or facing a compressor, we'll show you the honest math on repair versus a new high-efficiency system, with a free estimate either way.
For most Northern Virginia homes, yes. A right-sized, efficient heat pump moves heat instead of burning fuel, which usually means lower energy bills, especially in our mild shoulder seasons.
