Air Conditioning

Expert AC services for comfortable and energy-efficient cooling and ventilation. Our certified technicians install, repair, and maintain systems ensuring control for your home or business.

About the service

DC summers are not the time to find out your AC isn't ready. Tim Whistler Plumbing's HVAC team installs, repairs, and maintains residential and commercial cooling systems across Maryland, Virginia, and Washington DC, from central AC and heat pumps to ductless mini-splits and full duct replacements. We size every system properly, install it to manufacturer spec, and tune it for the efficiency you're actually paying for.

If your unit is short-cycling, blowing warm air, leaking water, or your energy bill jumped this year, we'll find the actual cause (refrigerant level, capacitor, compressor, blower motor, ductwork, or controls) and tell you straight whether to repair or replace.

A correctly sized and properly installed AC system can run 15 years or more. An undersized or poorly installed one will cost you in comfort and energy every month for as long as you own the home.

We service all major brands and offer annual maintenance plans that catch small problems before they become a no-cool call on a 95 degree day. Older brick rowhomes in Capitol Hill and Georgetown, mid-century ranchers in Silver Spring and Falls Church, and newer construction across Northern Virginia all have different cooling challenges, and our techs know what to look for in each.

What we handle

Central AC installation and replacement, heat pump installation and repair, ductless mini-split systems, ductwork repair and replacement, refrigerant leak detection and recharge, capacitor and compressor replacement, thermostat upgrades including smart thermostats, AC tune-ups and seasonal maintenance, indoor air quality improvements, and 24/7 emergency cooling repair across Bethesda, Arlington, Alexandria, Fairfax, Tyson's Corner, Springfield, Frederick, and the rest of the DMV.

FAQs

Common Questions You May Have

These are the most common questions people ask our professional plumbers and electricians.
Do we install tank and tankless water heaters?

Yes. We install, replace, and service traditional tank water heaters and ENERGY STAR rated tankless gas systems for homes and businesses across Washington DC, Maryland, and Northern Virginia. We handle the gas, water, and venting work in-house since our team is licensed across plumbing, gas, and HVAC. Tankless conversions often qualify for utility rebates, and we'll walk you through which option makes sense for your home.

Do you install EV chargers and handle electrical panel upgrades?

Yes. Our licensed electricians install Level 2 EV chargers and handle full electrical panel upgrades (100A, 200A, and 400A) across the DMV. Older homes often need a panel upgrade to support modern loads like an EV charger, heat pump, or solar system. Every project is permitted, inspected, and brought to current code. Call 1-866-477-6190 for a panel evaluation.

Do you offer free estimates?

Yes. We provide free estimates for most installation and replacement projects, including water heaters, boilers, AC units, panel upgrades, gas line work, and full system installations. For diagnostic work on existing equipment (like an AC that isn't cooling), there may be a small service call fee that's credited toward the repair if you move forward. Call 1-866-477-6190 to schedule.

Do you offer 24/7 emergency plumbing, gas, HVAC, and electrical service?

Yes. Tim Whistler Plumbing offers true 24/7 emergency response for plumbing, gas, HVAC, and electrical issues across the DMV. Whether it's a burst pipe at 2 a.m., a suspected gas leak, a furnace that died on the coldest night of the year, or a panel that's tripping breakers, we have a licensed technician available. Call 1-866-477-6190.
