Repair & Maintenance

Major Air will assess your unit and depending on the diagnosis will repair it on the spot or, for more complicated issues, the unit will be brought to our state-of-the-art facility for repair.

We also offer pressure steam cleaning to rid your unit of those harmful contaminants, dust, spores and pollen that collect on your unit over the years. A clean machine will run more efficiently, not only saving on your electric bill but also the environment.

When it comes to Thru-The-Wall air conditioning and heating, Major Air Service Corp. is the most respected name in the industry and has been for over 45 years.
