Cooling Systems We Service in Northern Virginia
Central Air Conditioning
Still the most popular cooling choice in Northern Virginia, central AC systems deliver whole-home comfort through ductwork. Our team installs, repairs, and maintains central units in homes across Fairfax, Arlington, and Loudoun, keeping them efficient through long stretches of summer heat and humidity.
Ductless Mini-Split Systems
Ideal for homes without existing ductwork, ductless mini-splits provide flexible comfort and can lower cooling costs by up to 30%. They’re especially popular in older Alexandria and Arlington properties, basement apartments, or home additions where extending ducts isn’t practical.
Heat Pumps
Heat pumps offer efficient cooling in the summer and double as a heating solution in the winter — making them perfect for Northern Virginia’s variable seasons. With mild spring and fall weather, many homeowners in Fairfax and Loudoun counties rely on heat pumps as an energy-saving, all-in-one comfort system.

Frequently Asked Questions About AC Services
The team at HVAC & Plumbing Unlimited has seen it all when it comes to air conditioning repair, installation, and maintenance. That’s why we’ve put together some of the most common questions we receive from homeowners in Northern VA.
What AC services does HVAC Unlimited provide in Northern Virginia?
We handle everything from emergency AC repairs during July heatwaves to new system installations for homes across Arlington, Fairfax, Loudoun, and Prince William counties. Our team also provides seasonal tune-ups designed for the humid Mid-Atlantic climate, where heavy summer use can wear systems down quickly.
How do I know if my AC needs repair or full replacement?
In Northern Virginia, systems work hard through long stretches of 90°+ days and high humidity. If your unit is more than 8–10 years old, struggles to keep up during peak afternoons, or drives up your Dominion or NOVEC utility bills, replacement may be more cost-effective than repeated repairs.
Do you service all types of homes and AC systems in this region?
Yes. From ductless mini-splits in older Alexandria rowhouses to high-capacity central systems in newer Loudoun County builds, our technicians are trained on all brands and models. We adapt service to Northern Virginia’s mix of historic properties and modern suburban homes.
How often should I schedule AC maintenance in our climate?
Because Northern Virginia summers are hot and sticky, we recommend scheduling an annual tune-up each spring before the cooling season kicks in. Regular maintenance helps protect against mid-summer breakdowns and improves efficiency during the region’s highest humidity months.
Do you offer emergency service when the weather spikes?
Yes. Heat waves in this area can push indoor temps dangerously high, so HVAC Unlimited provides 24/7 emergency AC repair across the region — from Alexandria and Arlington up through Ashburn and Leesburg. We’re local, so we understand how urgent comfort and safety can be during those stretches.
What financing options are available for new AC systems?
We know a new air conditioner is a major investment. HVAC Unlimited offers financing options for qualified Northern Virginia homeowners, making it easier to install an energy-efficient system without delaying comfort during the hottest months.
Does my new AC installation come with a warranty?
Yes. As an authorized dealer for top brands, we provide manufacturer warranties along with our own workmanship guarantee. Homeowners in Fairfax, Loudoun, and surrounding areas can count on reliable coverage for both parts and labor.
Can AC service also improve my indoor air quality?
Absolutely. In Northern Virginia, pollen, dust, and humidity can make indoor air feel heavy. During tune-ups and installations, our technicians can recommend solutions like high-efficiency filters, UV lights, and dehumidifiers to keep your home’s air cleaner and healthier.
Call (703) 337-4892 today or book online now — let HVAC & Plumbing Unlimited keep your AC running strong when you need it most.
