Everything Your AC System Needs

We handle the full range of air conditioning services, from routine maintenance that prevents problems to emergency repairs that get you back to comfortable fast.

Massachusetts summers are unpredictable, but your cooling doesn’t have to be. We understand how humidity affects comfort, how older homes present unique challenges, and how to make systems work efficiently even when it’s 95 degrees and muggy outside.

Most AC systems need professional maintenance once a year, ideally in late spring before the heavy cooling season starts. This timing lets us catch potential problems before they become expensive breakdowns during heat waves. However, if your system is older than 10 years, runs constantly during summer, or you’ve noticed higher energy bills, twice-yearly service can help maintain efficiency and prevent costly repairs. Regular maintenance typically includes cleaning coils, checking refrigerant levels, testing electrical connections, and replacing filters – work that keeps your system running smoothly and efficiently.
First, check your thermostat settings and make sure your circuit breaker hasn’t tripped – these simple issues cause many service calls. If those aren’t the problem, turn off your system to prevent further damage and call for service immediately. While waiting for repair, close blinds and curtains, use fans to circulate air, and stay hydrated. If you have a basement or lower level, spend time there since cool air naturally settles. Don’t attempt repairs yourself, especially anything involving electrical components or refrigerant, as this can be dangerous and may void warranties.
Generally, if your system is less than 10 years old and the repair costs less than half the price of replacement, repair makes sense. However, if you’re facing expensive repairs on a system that’s 12-15 years old, constantly needs service, or struggles to keep your home comfortable, replacement is usually the better investment. Other signs pointing toward replacement include dramatically higher energy bills, uneven cooling throughout your home, or needing frequent refrigerant additions. We’ll always give you honest advice about whether repair or replacement makes more financial sense for your specific situation.
Several issues can cause this frustrating problem. A dirty air filter restricts airflow and forces your system to work harder while cooling less effectively. Low refrigerant levels, often from small leaks, prevent proper heat transfer. Dirty evaporator or condenser coils can’t exchange heat efficiently. Sometimes the issue is ductwork problems like leaks or blocked vents that prevent cooled air from reaching living spaces. In older homes, inadequate insulation or air sealing can overwhelm even properly functioning AC systems. A thorough diagnostic will identify the specific cause and determine whether you need simple maintenance, targeted repairs, or system upgrades.
Proper AC sizing depends on much more than just square footage. We calculate cooling load based on your home’s size, insulation levels, window placement, ceiling height, and local climate conditions. An oversized system cycles on and off frequently, wasting energy and failing to remove humidity properly. An undersized system runs constantly but never achieves comfortable temperatures. Most homes need between 1.5 to 5 tons of cooling capacity, but the only way to determine the right size is through professional load calculation. This ensures you get efficient cooling without overpaying for unnecessary capacity or struggling with inadequate performance.
Start with a programmable thermostat set to 78 degrees when you’re home and higher when away – each degree higher can save 6-8% on cooling costs. Keep air filters clean, seal air leaks around windows and doors, and use ceiling fans to circulate air effectively. Close blinds during the day to block heat gain, and avoid using heat-generating appliances during peak afternoon hours. Regular professional maintenance keeps your system running efficiently, potentially saving 10-15% on energy costs. If your system is more than 10 years old, upgrading to a high-efficiency unit can significantly reduce monthly bills while improving comfort.
