Major Types of HVAC Equipment in Reston
There’s more than one way to heat and cool a home. Below is a quick break down of the equipment you might see in Virginia:
What Is It: This unit cools your home by removing heat and humidity from the indoor air. Known as a central air conditioning system, it operates with an outdoor unit and an indoor coil.
How Do I Know I Have One: Air conditioners use ductwork to distribute cool air throughout the home. The outdoor unit is usually found outside the house, while the indoor coil is placed in the duct system near the furnace.
Life Span (Years): 10-15What Is It: It’s large, in-charge, and responsible for heating your home. Typically referred to as a central heating system, this piece is set apart from boilers by its lack of a tank.
How Do I Know I Have One: These units rely on ductwork to move warm air around. They’re typically located in the center of the home.
Life Span (Years): 15-20What Is It: When it comes to flexibility, it’s hard to beat a heat pump. Able to alternate between heating and cooling, these units merge the functionality of an AC unit and furnace. They’re also ultra-efficient. These units can be ducted or ductless.
How Do I Know I Have One: You flip your thermostat to HEAT and the exterior unit turns on. You had to add an air handler.
Life Span (Years): 10-15
What Is It: In homes in Reston with central HVAC, the furnace’s blower motor is responsible for air distribution. For people with heat pumps or just air conditioners, an air handler is installed to take its place.
How Do I Know I Have One: You don’t have central heating but still have a large box in your home. It typically has a slot for your air filter.
Life Span (Years): 15-25
What Is It: Though sometimes able to alternate between heating and cooling, not all mini-splits are heat pumps. They’re a go-to choice for people who want to add air conditioning to a ductless home. They’re also an ideal option for additions and garages.
How Do I Know I Have One: These units feature wall mounted units called cassettes. You also lack ductwork.
Life Span (Years): 20-25

Dave's Reviews
EXCELLENT Based on 56 reviews Karen PlanteNovember 18, 2024Trustindex verifies that the original source of the review is Google. I have been a customer of Dave’s Heating and Air Conditioning for 20 years. From day one they have been the absolute best! They are always professional, courteous and reliable. They are reasonably priced as well. I woke up with no heat on a recent Sunday and they were quick to respond and come out to repair my furnace. I would highly recommend them to anyone. Love these guys! Veronica MooreNovember 18, 2024Trustindex verifies that the original source of the review is Google. I highly recommend Dave’s Heating and Air Conditioning! Adam went above and beyond. He not only helped me, he answered all my questions and took the time to educated me along the way. Thanks Adam! Matthew LopataOctober 17, 2024Trustindex verifies that the original source of the review is Google. I’ll give credit where credit is due. Dave’s Heat & AC did a great job replacing our system, especially given the immediacy of the situation. Even when one of the factory parts arrived damaged, they went out of their way (on a weekend no less) to get a replacement part so our system was operational with little down time. Both techs (Adam & AJ) have serviced our system prior and were instrumental in this new installation. In sum, we have been a Dave’s customer for years and will continue to stay with them as they have proven themselves to be a dedicated and responsive service. Andrew GuernseyOctober 14, 2024Trustindex verifies that the original source of the review is Google. I recently had an HVAC system replaced in our home in Herndon with a new heat pump and air handler by Dave's Heating & Air Conditioning. We learned about them from a glowing recommendation from a neighbor, and couldn't be happier with our experience! The team was incredibly professional, arriving on time and ready to work, and finished all in the same day. During the consultation, Todd took the time to answer all my questions, offered competitive pricing, and provided detailed information-- and made us feel comfortable throughout the process. The installation process was seamless. The technicians, Adam and Anh-Jon, in particular, did a great job, were efficient and respectful of my home, making sure everything was cleaned up before they left. The new system is working wonderfully—much more efficient and quieter than my old one! Thank you for a fantastic job! Anne McCloskeySeptember 20, 2024Trustindex verifies that the original source of the review is Google. I just had my HVAC system replaced by Dave’s. The team was professional, courteous, efficient, and careful. They did a great job cleaning up and leaving everything neat and tidy. They walked me through everything I needed to know and answered all my questions. I highly recommend Dave’s - I’ve been using them for years and they always come through! Timothy CalkinsSeptember 9, 2024Trustindex verifies that the original source of the review is Google. The crew who replaced our heat pump did a great job; all 3 men were extremely personable and thorough. They did a good job of cleaning up when they were done, too. Lindsey GrilliotAugust 31, 2024Trustindex verifies that the original source of the review is Google. My family has been a customer of Dave’s Heating and Air Conditioning for years. They treat their customers well and are experts in their field. Most recently we had to have our AC unit replaced and they were so kind to send over a portable unit on a Friday night to help us get through the weekend in comfort. They worked diligently to get the unit installed perfectly on a very hot day and helped us find the best method to finance the new unit. I would recommend Dave’s to everyone not just for their expertise, but for their excellent customer service. Russell NeelyAugust 29, 2024Trustindex verifies that the original source of the review is Google. Dave’s installed a new gas furnace and AC unit in my home last weekend and did a superb job. Adam and his team started on time and spent the whole day removing the old units and installing the new ones and updating all the various connections. They even made way for a plumber to install a new hot water heater at the same time in the same space, which was helpful to me and very gracious on their part because it delayed their work a bit. At all times Adam and his team were courteous and professional and explained what they were doing. After installation Adam showed me how to work the new system and was very helpful. I highly recommend Dave’s for any HVAC work you need. Also, the new owner Javier came to check out the work and meet and thank me, which I appreciated very much. 5 Stars!
