Air Conditioner Repair

With the right equipment and regular maintenance, your heating and cooling systems can pay you back. Our NATE-certified technicians are trained to maintain and repair central air conditioners and heat pumps from Carrier and all other brands. If you are experiencing problems with your furnace or AC system, we’ll make sure that your system is working properly, and we won’t leave until the job is complete and your home is comfortable. In this busy world, we understand the importance of prompt appointment scheduling and reliable service. We even offer 24-hour emergency service and after-hours air conditioner repairs that fit your busy schedule.


Indoor Air Quality

Believe it or not, your HVAC system can affect your health. Because the air is recycled in a contained space, airborne particulates like pet dander, allergens, mold, fungi, cleaning chemicals, and more can become a major issue. We specialize in ensuring the indoor air quality of your Northern Virginia home is of the highest level. To this end, we offer a full line of indoor air quality products and services, including air purifiers, ventilators, humidifiers, UV lamps, and air duct cleaning. Our qualified technicians are trained to ensure your family breathes easily.



Financing your new equipment is a simple process. Our financing programs are very competitive and our full-service financing team has the experience to work out the best plan for your situation and then guide you through the process. There is no down payment required, and no penalty for paying off your loan early.

Brennan's Heating & Air Conditioning Van

The HVAC industry has grown a lot since Brennan’s Heating & Air Conditioning opened. Today, high-tech comfort systems require highly-trained technicians who are NATE-certified and experienced in all areas of air conditioning repair, heating, and indoor air quality. After 35+ years, we’ve changed a lot too. At Brennan’s Heating & Air Conditioning, we still provide good, old-fashioned service, but we also offer the full line of cutting-edge products from the heating and cooling experts at Carrier.
