HVAC Preventative Maintenance and Furnace/AC Tune-Ups for Residential and Commercial Customers in and near Anaheim, CA

At McMaster Heating & Air Conditioning, we recommend regular AC and furnace tune-ups to ensure the longevity, safety, and efficiency of your HVAC equipment. We provide Anaheim home and business owners with thorough multi-point heating AC and furnace inspections and maintenance at competitive prices. During a residential or commercial service visit, we will check all essential systems and components, including electrical connections, evaporator coil, piping, motor, thermostat, and more. If we notice any causes for concern during our inspection, we will inform you immediately and provide an expert recommendation on the most cost-effective solution for your needs and budget.

As a general rule, most residential HVAC systems require biannual maintenance (spring AC tune-up and fall furnace tune-up), while commercial systems may require more frequent maintenance on a quarterly or monthly basis. Contact us today for expert advice on the ideal maintenance schedule for your make and model of HVAC equipment, as well as your average usage. HVAC tune-ups can be scheduled as part of a regular preventative maintenance program or as a standalone service.

Back in Feb 2010 I was shopping for center AC for my house. I went to carrier website and only look for authorized dealer with platinum service. 4 companies show up in my area so I decided to call all 4 companies for bidding. Among with all other 3 bidders Ron from McMaster did offer me most cost saving plan and suggestion. He is very easy to work and give out very useful information as far as type of equipments, optional package and installation date. He also provided me the necessary information for my tax return and rebate information. Now the AC is been installed for more than 3 months and I am still very happy with it.

A 10+ JOB

We did not know Ron McMaster prior to having him work in our home. Ron is a wonderful person to work with...we feel he is honest and he delivered what he promised. We feel Ron is knowledgeable about his product & gave us a very reasonable quote for our new air conditioner & heater along with some extra repair work done in our home. The job was done in a timely manner as promised. Ron's crew is very professional and they took great care to keep our home neat and tidy during and after the installation. We highly recommend Ron and his company...Mc Master Heating and Air Conditioning. The Coy's
