"My experience could not have been better, every time I needed Ariel. More than once my medical practice has had air conditioning problems and he has done everything he could resolve the situation as fast as possible. The same has happened at my home. I have the utmost respect for him and his business. He is efficient, very responsive and his price is very fair. He has never disappointed and I think anyone can expect the same outcome!!"

"We've had two visits by Core Mechanical.
One for diagnosis and customer approved temporary repair to allow time to acquire a replacement unit.
Second for replacement of faulty a/c unit.
Both occasions the service tech telephoned with expected arrival, and an updated weather delay.
Services performed quickly and with no difficulties.
Costs were as quoted.
We were happy to provide a gratuity beyond the quoted price.
We would not hesitate to recommend Core Mechanical to anyone needing their services.

Heating and Air Conditioning questions, answered by experts

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.

Yes, a mini split AC system can replace central air—and quite easily, too. Since mini splits don’t require ductwork, homeowners can convert their central air system to a mini split to save money and energy. Consult with an HVAC professional to learn more about the process of replacing your central air with a mini split.

Yes, mini-split systems are generally less expensive to run than central air conditioners and are significantly more energy-efficient. Because mini-splits do not rely on ductwork, they avoid the energy loss associated with ducted systems, allowing cooled or heated air to reach its destination more efficiently. Additionally, they offer zoned control, meaning you can run units in individual rooms and turn them off in unoccupied areas. This capability can lead to energy savings of about 30% compared to a central air system, resulting in a lower monthly energy bill.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.

The best time of year to purchase or replace an HVAC system, including components like an air conditioner or furnace, is during the off-season—spring and fall. During these periods, HVAC professionals are less busy than in summer and winter, when extreme temperatures create urgent demand. Shopping during the off-season can lead to savings of 10% to 15% on an AC unit and allows you more time to find the best deal and other cost-saving incentives. Typically, air conditioning units go on sale in the fall after demand drops, while furnace prices tend to decrease in the spring.
