17 HVAC Maintenance Contractors in Salem, NH

Salem sits in southern New Hampshire's climate zone where winter temperatures drop to around 20 F and the heating season stretches from October well into April, followed by humid summers that push indoor thermometers toward 82 F. This dual demand cycle makes regular HVAC maintenance in Salem a practical consideration for homeowners rather than a luxury. Seventeen contractors serve the area, and their combined average rating of 3.3 based on 148 reviews reflects a market where quality varies significantly between providers.

Homeowners budgeting for a furnace tune-up can expect to pay between $82 and $227, while an AC tune-up typically runs $72 to $206, and a full HVAC inspection costs anywhere from $155 to $412. These price differences often reflect the depth of diagnostic work and the comprehensiveness of the service checklist. In New Hampshire, contractors must hold a Class A, B, or C license from the Office of Professional Licensure and Certification, and local permitting requirements add another layer of accountability that reputable companies navigate routinely.

Customer feedback points to clear differences in service approach.

B&B Mechanical Services draws similar enthusiasm in seven reviews highlighting professional demeanor across both residential and commercial work.
