Keep Your System Running at Peak Efficiency
All air conditioning units need regular tune-ups and maintenance to stay efficient and reduce the number of repairs over their lifetime. Southern New Hampshire summers bring enough heat and humidity to push cooling systems hard, and a neglected system doesn’t just run inefficiently. It can fail early. Skipping routine AC maintenance in Salem, NH can put you on the fast track to an unplanned installation or full replacement.
Cornerstone Services has been serving residential and commercial customers throughout Rockingham and Hillsborough counties and the surrounding communities of southern New Hampshire for over 20 years. We’re based in Salem and offer same-day service for customers who need help quickly. Whether your home runs a central system or portable and window units, our technicians handle both and are transparent about any repair needs discovered during the visit.
Ready to schedule your AC tune-up? Call Cornerstone Services at (603) 874-1402. We can often get someone out the same day.
What’s Included in an AC Tune-Up
An air conditioning tune-up isn’t a quick filter swap. The service is designed to be thorough so early signs of trouble are detected and addressed before they turn into more expensive repairs. Our technicians inspect, clean, and lubricate components throughout the system, covering the mechanical, electrical, and refrigerant systems that homeowners can’t safely assess on their own.
A Cornerstone Services AC tune-up includes:
- Cleaning of the condenser and evaporator coils
- Inspecting refrigerant levels and checking for coolant leaks
- Recalibrating your thermostat
- Inspecting the ductwork
- Confirming all electrical connections are secure and safe for system operation
- Rating the performance and condition of the blower belt and motor
- Changing air filters
If you use a portable or window unit air conditioning system, our tune-up services include inspection of window seals to help maintain efficiency. For central air conditioning systems, air duct cleaning may be recommended as part of a broader preventive maintenance plan. Our technicians can advise you on what your system actually needs, not what runs up the bill.

Every worker we send to your property has passed a background check. When the job is done, your home is left clean. Our technicians don’t leave a mess behind.
Financing is available for larger service needs. Ask about current terms when you schedule. We also run monthly promotions on scheduled services, so it’s worth asking what’s current when you call.
