Affordable Preventative Maintenance for All Major Makes & Models of Furnaces, Heat Pumps & Packaged Systems

NES Mechanical provides the San Gabriel Valley with expert preventative maintenance services for all residential and commercial heating systems. Our heater tune-ups are affordably priced and highly effective at preparing furnaces or combined HVAC systems for the coldest months of the year. By scheduling maintenance visits on a regular basis, you'll help your heater run smoother and more efficiently, catch problems early, improve indoor air quality, and extend the life of your system. Over the last 34 years, we've provided our HVAC maintenance services to thousands of satisfied clients and earned a reputation for quality workmanship, reasonable prices, and exceptional customer service.

Comprehensive 14-Point Tune-Ups for Improved Performance & Energy Efficiency of Your Heater

With NES Mechanical, you'll always get a comprehensive heater tune-up performed by an experienced, highly skilled technician. Our 14-point tune-up includes running diagnostic checks, ensuring that the furnace is operating safely and properly, cleaning the equipment and components, lubricating moving parts, tightening any loose connections, and other general maintenance procedures. This tune-up is provided by one of our NATE-certified HVAC service technicians, who are thoroughly familiar with the industry's best practices for maintaining and repairing all major brands of furnaces, air conditioners, heat pumps, packaged systems, and ductless mini-splits. Additionally, because we're a Carrier Factory Authorized Dealer, our technicians have received specialized training directly from Carrier.

Reviews

" This is business that really cares about the customer. They were honest, professional, and helpful in every step of the process. We could not repair the old system (more than 30 years old), so they gave us options, and let us choose what was best for us . . .
