AC Maintenance in Westborough

NATE Certified Technicians Serving Westborough Since 1991

CPS Heating & Cooling has been locally owned and operating in Westborough for over 34 years. We know this community because we’re part of it, and that history shows up in every maintenance call we make across the Boston Metro West area. Our technicians are NATE Certified, meaning they’ve demonstrated working proficiency on today’s complex cooling systems well beyond what basic state licensing requires. We service all makes and models, whether we installed your system or not.

We hold an A+ accreditation with the Better Business Bureau and have been named a Nextdoor Neighborhood Favorite, recognition that comes directly from the people we serve. Every visit starts with honest communication and ends with a clean work area. Air conditioning maintenance estimates are 100% free, with no pressure and no upfront diagnostic cost.

Ready to schedule your AC tune-up? Call us at (508) 501-8848 or reach out online. We’re available 24/7, so you’re never stuck waiting for business hours to get answers.

What We Cover During an AC Maintenance Visit

A thorough maintenance visit isn’t a quick visual check. Our technicians take a diagnostic approach, tracing issues to their root causes rather than addressing surface symptoms. That discipline can save homeowners money on repairs that wouldn’t have been necessary with an accurate assessment upfront.

A professional air conditioning maintenance visit with our team typically includes:

Refrigerant level and pressure check to confirm the system is operating within manufacturer specifications
Electrical component testing to identify worn contactors, capacitors, or connections before they fail
Thermostat calibration to verify accurate temperature sensing and staging
Coil inspection and cleaning for both the evaporator and condenser coils
Filter replacement or cleaning based on current condition
Condensate drain clearing to prevent water backup and moisture damage
Lubrication of moving parts to reduce friction and mechanical wear
Airflow and temperature split verification to confirm the system is delivering consistent cooling

Most AC manufacturers require annual professional maintenance to keep equipment warranties valid. We can walk you through exactly what we found and what your options are, in plain language and without pressure. Scheduling once a year, before cooling season starts, is the standard recommendation for helping keep a system running reliably.

Preventative Maintenance Membership

A one-time tune-up is a good start. Our Preventative Maintenance Membership is a better long-term strategy. Members receive ongoing care for their AC and heating systems with concrete benefits that go well beyond a single annual visit.

Membership includes:

Priority scheduling over non-member customers, so you move to the front of the line when demand is high
Automatic reminders for spring and fall inspections so nothing slips through the cracks
50% off the standard diagnostic fee on contracted equipment
15% off all repairs on contracted equipment
Multi-point inspection on every visit, plus filter replacement or cleaning as needed and lubrication and safety testing of contracted equipment

We’re also a Mass Save program partner. Homeowners who pair regular maintenance with qualifying efficiency upgrades can access rebates and incentives through that program, and we can help identify where those opportunities apply to your home. If a maintenance visit surfaces a system nearing the end of its useful life, flexible financing options are available for homeowners considering an upgrade.

Properly maintained systems can run more efficiently and are less likely to require the kind of mid-season service that leads to an emergency call. Membership is a cost-effective way to stay ahead of that.

Why Annual AC Maintenance Matters in New England

Massachusetts summers bring a combination of humidity and sharp temperature spikes that put sustained demand on residential cooling systems. Equipment that hasn’t been serviced carries that load with components operating outside their ideal conditions, accelerating wear in ways that aren’t visible until something fails.

The most common culprits are also the most preventable. Refrigerant leaks, blocked condensate drains, dirty coils, and clogged filters are inexpensive to address during a scheduled visit. Left unattended, each can escalate into a major repair or a full system failure, typically during the stretch of summer when demand is highest and wait times are longest.

Beyond helping reduce the risk of breakdowns, a well-maintained system can operate more efficiently. It can move air more consistently, hold temperature more evenly, and avoid working harder than it needs to, which can translate to lower utility costs over a cooling season. Annual air conditioning maintenance also helps homeowners stay ahead of decisions about their equipment, turning system replacements into planned investments rather than emergency ones.
