Serving Northern Virginia

Why Northern Virginia homeowners choose Leonard Splaine for air conditioning

Every AC job Northern Virginia summers demand

Cooling a Northern Virginia home means brutal July humidity, older houses with tricky ductwork, and newer builds already on their second system. After 70 years here, we've seen all of it. We repair every brand of AC, right-size replacements with a real load calculation, and install ductless mini-splits for the rooms that never quite cool.

Certified techs, flat-rate pricing, family-owned

Cooling season is when fly-by-night operators flood the market, so it's worth knowing who you're letting into the house. Our AC techs are certified employees, the pricing is flat-rate and in front of you before work starts, and the family that founded this company in 1956 still owns it three generations later.

A real person answers, same-day trucks roll

A real person answers your call any hour you dial, and most cooling calls get a truck the same day, whether it's a repair, a tune-up, or a free replacement estimate.

Air Conditioning Repair

When the AC quits on the first 95° day, we run same-day AC repair across Northern Virginia. Our certified techs fix every brand and every breakdown: systems that won't cool, frozen evaporator coils, refrigerant leaks, burned-out capacitors and compressors, failing blower motors, clogged condensate drains, weak airflow from blocked vents and ducts, units that short-cycle on and off, and thermostats that won't hold a setpoint. You get a straight diagnosis and upfront, flat-rate pricing with no hidden fees before any work starts, and most repairs are done the same visit.

  • weak airflow
  • frozen coils
  • refrigerant leaks
  • compressor & capacitor

From older homes to newer subdivisions, we match the system to the house. As a Lennox Premier Dealer we offer free replacement estimates, 0% financing options, and next-day installs on most systems.

Ductless Mini-Splits

Older Northern Virginia homes without ductwork, plus additions, sunrooms, and converted garages, are ideal for ductless mini-splits. As a Mitsubishi Diamond Contractor we design and install single- and multi-zone systems that heat and cool efficiently and quietly, without tearing your walls apart. It's the fix when one room is always too hot or too cold.

  • single & multi-zone
  • additions & sunrooms
  • garage conversions

AC Maintenance & Tune-Ups

The cheapest repair is the one you never need. Our Northern Virginia tune-ups check refrigerant levels, clean the coils, and catch weak capacitors and worn components before they turn into a July breakdown. Regular maintenance also protects efficiency, extends the system's lifespan, and keeps your manufacturer warranty valid. Ask about our maintenance plan for priority scheduling, waived diagnostics, and a discount on any repairs you do need.

  • seasonal tune-ups
  • coil cleaning
  • refrigerant levels
  • extends lifespan
  • maintenance plans
  • warranty

Refrigerant Recharge & Leak Repair

Low refrigerant almost always means a leak, not just a top-off. Our Northern Virginia techs find and seal the leak, then restore your refrigerant levels to the exact factory charge, whether you're on older R-22 or newer R-410A. The right charge means colder air, lower power bills, and a compressor that isn't running itself to death.

  • refrigerant recharge
  • freon leak
  • leak detection
  • R-410A & R-22
  • weak cooling

Air Filters & Indoor Air Quality

The air your AC moves is the air your family breathes. We handle filter swaps, high-efficiency media filters, and indoor air quality upgrades like UV lamps, air purifiers, whole-home air cleaners, and humidifiers and dehumidifiers. For Northern Virginia homes fighting allergens, dust, pet dander, mold, and other pollutants, the right setup means healthier air, better humidity control, stronger airflow, and a system that doesn't have to work as hard.

  • media & HEPA
  • UV lamps & air purifiers
  • humidifiers

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.
Emma F. Yelp review
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.
Shawn R. Yelp review
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

Frequently asked questions about air conditioning in Northern Virginia

The questions Northern Virginia homeowners ask us most about air conditioning. Anything else, the phone's faster than the internet.

Can you repair my AC the same day?

In most cases, yes. We hold room in the daily schedule for same-day AC repair across Northern Virginia. Call before noon during a heat wave and we can almost always be there the same day, on any brand.

Should I repair or replace my air conditioner?

A good rule of thumb: if the system is under 10 years old and the repair is minor, fix it. If it's older, on R-22 refrigerant, or facing a major repair like a compressor, replacement usually costs less over time. We give you the honest math and a free replacement estimate, never a scare tactic.

What size air conditioner does my house need?

We never guess. Before we quote a new system we run a Manual J load calculation on your home, factoring square footage, insulation, ductwork, windows, and sun exposure. An oversized AC short-cycles and struggles with humidity; an undersized one never keeps up. Right-sizing is the whole game.

Do you service every brand of air conditioner?

Yes. Our certified techs repair every major brand of AC and heat pump. For new installs we are a Lennox Premier Dealer and a Mitsubishi Diamond Contractor, and we also install Carrier, Trane, Goodman, and more.

How often should I have my AC maintained?

Once a year, ideally in spring before cooling season. A yearly tune-up keeps efficiency up, catches worn parts before they fail in July, extends the system lifespan, and keeps your manufacturer warranty valid. Ask about our maintenance plan for priority scheduling and waived diagnostics.
