Routine Air Conditioning Maintenance and Tune-Ups Are Vital for the Upkeep of Your Home’s Air Conditioning

Bordered by Long Island Sound, the Atlantic Ocean, and East River, summers in Long Island tend to be hot, humid, and at times, unbearable. With the temperature tipping at 82 degrees F outside, the only time you really want to be outside is when you’re picking up a BEC for breakfast (or a hero for lunch).


MJC Air is a full-service air conditioning service, repairs, and maintenance solutions provider. Our services include scheduled A/C maintenance, tune-ups, repairs, and emergency services for residential homeowners in Nassau and Suffolk counties.

Quick & Efficient

Air Conditioning Tune-ups


A quick inspection and tune-up by our experienced A/C technicians can help resolve any visible and invisible issues in your home’s air conditioning system before they turn into a major issue. It is important not to avoid or postpone an air conditioning tune-up if it’s required.


With an A/C unit, even small issues can end up causing serious damage to your air conditioning and can cost you thousands of dollars in repairs or the need for a new A/C installation. We help our clients in Suffolk and Nassau counties avoid unnecessary expenses with our regular AC tune-ups.
