What Proper AC Service Actually Gets You

Your AC system runs quietly in the background, maintaining the exact temperature you want without driving up your energy bills. No more sweating through hot nights or worrying about system breakdowns during heat waves.

When your air conditioning works properly, you forget it’s even there. That’s the goal. Your home stays consistently comfortable, your utility bills stay predictable, and you have one less thing to stress about during New England’s unpredictable summer weather.

The difference between a well-maintained AC system and one that’s been neglected is night and day. Regular maintenance catches small issues before they become expensive emergencies, extends your system’s lifespan, and keeps your indoor air quality where it should be.

Most AC systems need professional maintenance once a year, ideally in late spring before the heavy cooling season starts. This timing lets us catch any issues that developed over the winter and make sure your system is ready for summer demand. If you have an older system or one that runs heavily, twice-yearly service can help prevent breakdowns and extend its lifespan. Regular maintenance typically includes cleaning coils, checking refrigerant levels, inspecting electrical connections, and replacing filters – all things that directly affect how efficiently your system runs.
Call for service right away if your AC is blowing warm air, making unusual grinding or squealing noises, or cycling on and off constantly. Ice forming on the unit, water leaking inside your home, or electrical issues like tripped breakers are also signs that need immediate attention. Strange smells, especially burning odors, should never be ignored. These symptoms usually indicate problems that will get worse quickly if left alone, often leading to more expensive repairs or complete system failure during the hottest days of summer.
Simple repairs like replacing a capacitor or cleaning clogged drain lines usually take 30-60 minutes. More complex issues involving refrigerant leaks, compressor problems, or electrical repairs can take 2-4 hours depending on the specific problem and parts availability. We always give you an estimated timeframe once we’ve diagnosed the issue. Most repairs can be completed the same day, though some situations requiring special parts might need a follow-up visit. Emergency repairs get priority scheduling, especially during heat waves when AC failures are most critical.
If your AC is over 10-12 years old and needs a major repair costing more than half the price of a new system, replacement usually makes more financial sense. However, minor repairs on older units can still be worthwhile if the system has been well-maintained. We’ll give you honest advice about whether a repair is a smart investment or if you’re better off upgrading. Factors like energy efficiency, refrigerant type, and your long-term plans for the home all play into this decision. Sometimes a repair buys you time to plan for replacement rather than dealing with an emergency installation.
Change your air filter regularly – every 1-3 months depending on the type and your home’s conditions. Keep the outdoor unit clear of debris, leaves, and vegetation that can block airflow. Don’t ignore small problems like unusual noises or reduced cooling performance, as these often signal issues that will get worse. Schedule annual professional maintenance to catch problems early and keep your system running efficiently. Also, avoid constantly adjusting your thermostat, which makes your system work harder than necessary and can lead to premature wear.
