"It went better than I could have imagined. All the other calls I made required a repair technician appointment and a separate salesperson appointment. Vitaliy the HVAC Doctor was extremely knowledgeable -- able to repair our old A/C enough to get us through until the new A/C was installed AND get us set up with a new one. We got a great new 2-stage A/C at a terrific price. Vitaliy really knows HVAC, and did a super job. Also, he has an incredible work ethic. He fit us in on short notice on a Saturday, and took his time answering all our questions. Once we were satisfied with the solution, he fixed everything by headlamp in the dark. He made sure we never felt pressured or rushed. We absolutely have a new favorite HVAC company."

"We were very impressed with Mike and his team. They were prompt, communicative and professional. We had not had our ducts cleaned for a considerable time and it showed! Integrity took before and after pictures to show their work and they did a phenomenal job. They also gave us pointers for things to watch for. We will definitely be using them again in the future and make this a part of our regular annual routine."

"B&D did a great job replacing my 19 year old inefficient furnace and AC unit. The guys pulled new vent lines and new AC piping out the side of my home with only a 2' x 4' opening in the ceiling of a room adjoining the mechanical room (the old furnace was flue vented). I was surprised they could get this done in such a tight space. In addition to the furnace install they cleaned up the routing of our gas supply manifold and some of the furnace duct work in the furnace room. This was above and beyond what I expected. The furnace room looks more open and cleaner after they finished the job. They finished the work in two days. They were on time, courteous, and left a clean work area when everything was completed. I'd gladly hire B&D for any future needs."

"We met serviceman Alex L. from DJ's today. He worked as long as it was necessary to diagnose and fix issues with our furnace humidifier. It needed several adjustments. He worked very diligently and the price was reasonable (especially by today's standards for pricing). We would definitely hire DJs again for other HVAC and plumbing work. We also appreciated the company's thoroughness in providing reminder calls and other contact on the day of service to ensure we met Alex at our home at the right time. This shows an emphasis on customer service that we appreciate. Both Charlotte and Karen were very helpful to us on the phone today as well."

Heating and Air Conditioning questions, answered by experts

Replacing an HVAC system does not always include new ductwork. The decision depends on the condition of your existing ducts. If they are in good shape, correctly sized for the new unit, and meet current standards, they can often be reused. However, if the ducts are damaged, poorly designed, or improperly sized, they will likely need to be replaced or upgraded to ensure the new system operates efficiently. An HVAC contractor will assess your ductwork and recommend the best course of action. Typically, ductwork is purchased separately, and a full replacement will add to the overall project cost.

Most AC repair technicians will take between two and six hours to carry out repairs, depending on the work needed and the accessibility of the unit. For example, recharging refrigerant lines should take one to two hours to service, while replacing a compressor, blower fan, or other major components can take five to eight hours. You can ask your AC repair technician how long they expect the job to take, but just in case, you should plan on being home and available for most of the day.

Yes, having mismatched evaporator and condenser coils in your AC system can lead to serious issues. For instance, it can result in higher monthly energy costs as the system runs longer to compensate for the mismatch. This mismatch can also put extra stress on the system, compromising its efficiency and longevity. 

Along with that, mismatched coils can lead to higher temperatures and humidity levels in the home. What’s more, using coils of different sizes may violate the manufacturer's warranty, as they are designed to work synergistically, and any mismatch could lead to repairs and system failure.

DIY is possible for basic cleaning. Professional services handle advanced maintenance like recharging the refrigerant.

Whether an HVAC damper should be open or closed depends on the season, the zone it controls, and the temperature in that zone. In the summer, open upstairs dampers and close lower-level dampers to get the most efficient cooling possible. In the winter, do the opposite. Cool air will naturally flow down to lower levels, while warm air will rise. This keeps your system from working harder and helps prevent common AC problems.
