  • Trucks that are stocked daily with parts to provide you with immediate repairs to fix your system and restore your comfort.
  • Technicians that go through a plethora of background checks and random drug tests (where permitted by law) throughout their employment, so you can rest assured you're in the best possible hands.
  • Comfort consultants and service technicians that will treat your home and family with courtesy and respect, just as they'd treat their own homes.

Air Conditioning Services

K2 Mechanical specializes in air-conditioning services and repair for residential homes. Whether it's a full AC system replacement, new installation of any central air conditioning system brand or repair, or a new installation of HVAC ductwork, we have you covered.

If the time has come to replace your central air conditioning system, let our experienced, knowledgeable sales team consult with you concerning your comfort needs. We can offer you the best advice on which HVAC system will offer you the best long-term savings and energy efficiency to meet your comfort needs.

Heating Services

No matter what heating service you're in need of, we are here to assist you. If you need a new heating system, you can explore your HVAC options with our experienced team to discuss which type of heating system is right for you. If you're seeking repairs for your existing gas furnace or boiler, oil-fired system or heat pump, our technicians will diagnose your problem and repair it quickly to get your home back to an ideal comfort level.

24-hour Service Provider

Our office is staffed Monday-Friday from 7am to 8pm, and Saturdays from 7am to 5pm. However, our technicians are available 24-hours a day to handle your emergency needs. We provide flat rate pricing to ensure that all our customers are charged equally for every repair, regardless of how long the job may take. If you are an existing Service Agreement Customer and need after-hours or emergency service, you are not charged any overtime rates. If you are not a Service Agreement Customer and would like to inquire about this excellent program, please call our office for more information.

With any new installation, we also recommend our Preventive Maintenance Contracts that are customized to your individual needs. Improper maintenance can lead to costly system failure. Without a proper seasonal tune up, an air conditioner left unserviced can lose efficiency and cost thousands to fix. Our technicians will service or repair your AC system, heat pump or geothermal system in order to protect your investment by keeping your air conditioning system running efficiently. Be sure to ask your installation specialist how a maintenance contract can protect your investment.

If you're in need of any HVAC service, call our office at 800-531-2160 to set up an appointment.
