Complete AC Maintenance Duxbury

Everything Your AC System Needs

You get thorough air conditioning services that cover every aspect of your cooling system. Emergency repairs when something breaks. Regular maintenance that prevents expensive problems. When the time comes to replace an old system, we offer new installations.

The maintenance includes filter changes, coil cleaning, refrigerant checks, and electrical connections. This regular maintenance promises that your AC operates efficiently and prolongs its lifespan.

For Duxbury homes, that means dealing with salt air corrosion, high humidity levels, and the distinct challenges that come with coastal New England weather. Our technicians know these local factors and adjust service accordingly.

How often should I have my air conditioner serviced in Duxbury?

You should have your AC serviced once a year, ideally in late spring before the cooling season starts. In Duxbury’s coastal environment, the salt air can be particularly hard on outdoor units, so annual maintenance is essential for preventing corrosion and confirming efficient operation. During service, technicians clean coils, check refrigerant levels, inspect electrical connections, and replace filters. Such maintenance prevents most breakdowns and keeps your system running efficiently, which saves money on energy bills and extends the life of your equipment.

What should I do if my AC stops working during a heat wave?

First, check your thermostat settings and make sure the circuit breaker hasn’t tripped. If those are fine, check your air filter—a severely clogged filter can cause the system to shut down. If none of these simple fixes work, call for emergency AC repair immediately. Don’t try to fix refrigerant leaks or electrical issues yourself. While waiting for service, close blinds and curtains, use fans to circulate air, and stay hydrated. Most AC emergencies during heat waves are caused by dirty coils, low refrigerant, or electrical problems that require professional repair.

How do I know if I need AC repair or a complete replacement?

If your AC is over 10-12 years old and needs frequent repairs, replacement usually makes more sense financially. Other signs include rising energy bills, uneven cooling throughout your home, strange noises, or the system running constantly without reaching the set temperature. However, newer systems with minor issues are typically worth repairing. A qualified technician can assess your specific situation and give you honest advice about whether repair or replacement is the better investment. We’ll consider the age of your system, repair costs, and energy efficiency when making recommendations.

Why is my air conditioner freezing up in summer?

AC units freeze up when airflow is restricted or refrigerant levels are low. The most common cause is a dirty air filter that blocks airflow over the evaporator coils. Other causes include blocked vents, dirty coils, or refrigerant leaks. If your AC is frozen, turn it off immediately and let it thaw completely before restarting—this usually takes several hours. Check and replace your air filter, then try running the system again. If it freezes again, you need professional service to diagnose refrigerant issues or other mechanical problems that require specialized tools and knowledge.

How can I lower my cooling costs without sacrificing comfort?

Start with regular maintenance—clean systems run 15-20% more efficiently than neglected ones. Set your thermostat to 78°F when you’re home and higher when you’re away. Use ceiling fans to circulate air, which lets you feel comfortable at higher temperatures. Close blinds during the day to block heat, and make sure vents aren’t blocked by furniture. Replace your air filter regularly—dirty filters make your system work harder. Consider a programmable thermostat to automatically adjust temperatures when you’re not home. These simple steps can significantly reduce your energy bills without major investments.

What size air conditioner do I need for my Duxbury home?

AC sizing depends on your home’s square footage, insulation, window placement, and local climate factors. In Duxbury, coastal humidity and sun exposure affect cooling needs differently than inland areas. A system that’s too small won’t cool effectively, while an oversized system will cycle on and off frequently, wasting energy and not removing humidity properly. Professional load calculations consider your home’s specific characteristics, including ceiling height, insulation levels, and window efficiency. This confirms you get a system that cools efficiently without wasting energy or leaving you uncomfortable during peak summer heat.
