"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 questions, answered by experts

You will only need to refill your AC with refrigerant if it has a leak. Otherwise, a modern, well-maintained AC will most likely never need a recharge. You may notice a leak in an older system if your bills are higher, you hear a hissing sound, or if the air is blowing out hot.

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.

While most air conditioners can last between 10 and 20 years, they will only last this long (or longer) if properly taken care of. Routine maintenance and inspections help keep your AC unit running in tip-top shape but understanding what factors will decrease its lifespan will also help keep your unit running cool.

Some things that shorten your AC’s lifespan include:

  • Extreme outdoor conditions, like high humidity or extensive salt spray 

  • Improper installation

  • Extended run times, either by the unit being too small or the thermostat setting too low

  • Not performing required maintenance

Signs of a damaged evaporator coil include warm air from vents, frequent starts and stops without proper cooling, failure to turn on, refrigerant leaks, and unusual noises. If you suspect issues with your AC system or its components, it’s best to call an AC repair technician for proper diagnosis and repairs.

Unfreezing an AC unit is not a DIY project unless the problem is a dirty air filter. Changing out an air filter is easy for homeowners, but otherwise, trying to repair ductwork, refill refrigerant, or replace a blower fan motor are tasks best left to the pros. Otherwise, you could cause further damage to your cooling system or even harm to yourself.
