"We had a phone call and he actually helped me figure out that I might need a plumber instead of HVAC repair. Mark was very courteous and so helpful! If we do end up needing to go back to him I will definitely call for them to make a visit."

"This Company is top notch! They quickly responded to my urgent message in regard to no heat in the house and had the service guy arrive to the door right after completing another job. They were very professional and did the repair in no time and price quoted over the phone was exactly what was charged for the service. We will definitely call this Company again for any boiler repairs. Thank you!"

"Kahlil is very professional, takes his time to answer questions, arrived at appointed time even during a rain storm. During the course of the install, it was found wiring for the air conditioning needed to be changed from 110 to 220. Khalif found someone to take care of it immediately. The men working with him -Andy and Jose, were courteous, left the work site in a neat and clean order- they placed protective coverings down to protect my wood floors. We are now enjoying a comfortable evening in our home . I highly recommend Khalifa and his company"

Heating and Air Conditioning FAQs, answered by experts

You should know the main components of an air conditioner: the condenser coils, evaporator coils, drip pan, AC filter, ducts, and refrigerant. Each part plays a key role in the performance and safety of your AC system. When tracking the source of AC issues or odors, it helps to know where to look. Your outdoor unit houses your condenser coils, fan, and compressor. Your indoor unit houses your evaporator coils, drain lines, and filter, and it connects to your ductwork. 

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

As mentioned above, not all HVAC Schrader valves are necessarily the same. While the valve core and pin or spring size on Schrader valves used for HVAC are generally similar, the valves are not all universal and interchangeable. The size of Schrader valves varies depending on whether it's used in an air conditioner, bicycle tire, or motor vehicle tire.

An AC drip pan may stop draining if there’s a clog where the drip pan connects to the drain line. Clogs can form from a lack of cleaning or from rust or corrosion buildup. Cleaning the drip pan at least once per month lowers the chances of debris clogging the drain line.

As a general rule, you should have your HVAC system professionally serviced at least once a year, though it's best to follow the manufacturer's specific recommendations. Many experts suggest twice-yearly maintenance: once in the spring for the cooling system and once in the fall for the heating system. This is especially recommended for older units, systems with recurring issues, or heat pumps that provide both heating and cooling. Regular service, which can cost between $100 and $550, keeps the system running efficiently, helps prevent costly future repairs, and saves money on utility bills.
