Preventative Maintenance for All Major Makes & Models of Air Conditioners, Heat Pumps, Packaged Systems, and Ductless Mini-Splits

Preventative maintenance plays a major role in the performance of your air conditioning system. By investing in annual tune-ups, your air conditioner will provide more consistent temperature control, run smoother and more efficiently, have fewer breakdowns, and last longer -- all of which help to improve your indoor comfort and save you money.

Experts in Maintaining All AC Brands: Carrier, Bryant, Trane, Frigidaire, York & More

At NES Mechanical, we offer affordable and comprehensive air conditioner tune-ups. During a tune-up, we'll check that your cooling system is operating properly, perform diagnostic checks on pressures and temperatures, tighten and secure all connections, ensure that the condensation is draining correctly, clean the coils, replace or clean filters, and complete a variety of other general maintenance and cleaning procedures. These AC tune-ups are performed by our NATE-certified service technicians who have an average of 10+ years of experience. In order to earn NATE certification, our technicians needed to demonstrate a thorough knowledge of proper repair and maintenance procedures for all types of HVAC equipment from any major brand, including Carrier, Bryant, Trane, Frigidaire, American Standard, Tempstar, Lennox, Rheem, Goodman, Coleman, Luxaire, Ruud, York, Amana, and Maytag.
