Northern Virginia HVAC Experts —AC, Heating & 24/7 Emergency Service

"Cong is very friendly and professional, gets the job done right. Strongly recommend!"

"Our AC died on the hottest day of the year. Tran Air had a technician at our door within two hours and a brand-new system installed the next morning. Honest pricing, no upsell."

"I've used Tran Air for both my home and rental property. Always on time, always clean, always explains what they're doing. They earned a customer for life."

"Annual maintenance, duct cleaning and a furnace repair — every visit has been excellent. The technicians treat your home like their own."

"Got three quotes for a new heat pump. Tran Air was the most thorough, the most reasonable, and the only company that actually measured the airflow before recommending equipment."

"Emergency call at 9 PM on a Sunday. They picked up, walked me through what to check, and were out first thing Monday. That's real customer service."

"Cong replaced our 20-year-old furnace with a high-efficiency unit. Came in $2,000 under the other quotes we got and finished in one day. Couldn't be happier."

"Booked online at 7am, had a tech here by 11. Diagnosed a bad capacitor, replaced it on the spot for a fair price. No upsell, no drama. This is how HVAC should be."

"I manage a small office building and Tran Air handles all four of our rooftop units. Never had a missed appointment, always sends the same techs who know our system."

"Had them do a full duct cleaning before we moved in. Showed before/after photos, wore booties in the house, were genuinely kind to our dog. Air quality is noticeably better."

"Heat pump stopped heating overnight. Cong walked me through resetting the breaker over the phone and saved me a service fee. When it failed again the next day, he was here in 90 minutes with the right part."

"Tran Air installed two ductless mini-splits in our converted basement. Clean install, great explanation of the controls, followed up a week later to make sure everything was perfect."

"Annual tune-up turned into 'your blower motor is about to die.' They showed me the amp draw readings, gave me the option to wait or replace it, and there was zero pressure. Replaced it — saved a summer breakdown."

"Got a same-day quote, financing approved in minutes, new AC installed two days later. The whole experience felt like dealing with a friend in the business, not a sales pitch."
