What Your Repair Includes

Every AC repair service covers full system diagnosis, not just a quick look at the obvious problem. We check refrigerant levels, electrical connections, airflow, and all the components that affect how well your system cools your home.

You get quality replacement parts when needed, proper installation, and testing to make sure everything works together efficiently. We also clean up our work area and explain what we fixed so you understand what happened and how to prevent similar issues.

Our repairs come with clear warranties because we stand behind the work. Plus, if you join our Dempsey Comfort Club, you get priority scheduling and ongoing maintenance to catch small problems before they turn into expensive repairs or complete system failures during the hottest days of summer.

Response time depends on the season and current demand, but we prioritize emergency calls during heat waves when your AC failure affects your health and safety. During peak summer months, we typically respond within 24 hours for urgent repairs. Off-season repairs usually get scheduled within a few days. If you’re a Dempsey Comfort Club member, you get priority scheduling which means faster response times when you need service most. We understand that AC problems don’t wait for convenient times, so we work to get to you as quickly as possible.
The biggest culprits are dirty air filters restricting airflow, refrigerant leaks from aging coils, and electrical issues from power surges during summer storms. Massachusetts humidity also creates problems with condensation drainage and mold growth that can block airflow or damage components. Lack of regular maintenance compounds these issues because small problems turn into major failures. Many breakdowns happen right when you need your AC most because the system has been struggling with underlying issues that finally give out under the stress of hot weather and constant operation.
Age is the first factor to consider. If your system is over 15 years old and needs expensive repairs, replacement often makes more financial sense. Frequent breakdowns, poor cooling performance, and rising energy bills are also signs your system is failing. However, many problems that seem major actually have simple solutions when diagnosed properly. Our technicians can evaluate your system’s overall condition and help you understand whether repair or replacement gives you the best value. We’ll never push you toward a more expensive option when a quality repair will serve you well.
Yes, we handle emergency AC repairs when your system fails during extreme heat conditions that could affect your health or safety. Emergency service focuses on getting your cooling restored quickly, though some repairs might require ordering specific parts for completion the next business day. We prioritize calls from elderly customers, families with young children, and anyone with medical conditions that make heat dangerous. Our goal is to get you some level of cooling relief as quickly as possible, even if the complete repair takes additional time to finish properly.
Start with your air filter. A completely clogged filter can make your system stop cooling or shut down entirely. Check your thermostat settings and make sure it’s set to cool with the temperature below your current room temperature. Look at your circuit breaker to see if the AC breaker has tripped. Also check that your outdoor unit has power and isn’t blocked by debris, plants, or other obstructions. If these basic checks don’t solve the problem, you likely need professional diagnosis because most AC issues involve refrigerant, electrical components, or internal mechanical problems that require proper tools and training to fix safely.
AC repair costs vary widely depending on what’s actually wrong with your system. Simple fixes like replacing a capacitor or cleaning coils cost much less than major component replacements or refrigerant leak repairs. The age and type of your system also affects parts availability and labor time. We provide clear estimates before starting any work so you know exactly what you’re paying for. Our goal is to give you repair options that fit your budget while actually solving your cooling problems. Many customers find that investing in proper repairs costs less long-term than repeated cheap fixes that don’t address the real issues.
