Every AC Problem We Handle

Whether your AC won’t turn on, isn’t cooling properly, is making strange noises, or cycling on and off constantly, Dempsey Energy handles it all. We work on all major brands and types of air conditioning systems common in Quincy homes.

Our service includes diagnosing electrical issues, replacing worn components, fixing refrigerant leaks, cleaning dirty coils, and addressing airflow problems. We also provide AC tune-ups to catch small issues before they become expensive repairs.

What you won’t get is a sales pitch for a whole new system when a repair will do the job. We’re honest about when a repair makes sense and when replacement might be the better option for your situation and budget.

Response times depend on the season and current demand, but Dempsey Energy prioritizes emergency calls, especially during heat waves. We understand that a broken AC in the middle of summer isn’t just uncomfortable – it can be dangerous for elderly family members or young children. When you call, we’ll give you a realistic timeframe and do everything possible to get someone out the same day. For non-emergency repairs, we typically schedule within 24-48 hours and always confirm appointment times in advance.
Before any major repair work begins, you’ll get a detailed explanation of what’s wrong and a clear estimate of costs. Dempsey Energy believes in transparency – no surprise charges or pressure tactics. If your AC needs expensive repairs, we’ll help you understand your options, including whether repair or replacement makes more sense for your situation. We use quality parts that come with warranties, and our work is guaranteed. You’ll never be pressured into spending more than necessary.
Yes, Dempsey Energy works on all major AC brands and system types commonly found in Quincy homes, including central air systems, ductless mini-splits, heat pumps, and window units. Our technicians have experience with older systems as well as the latest high-efficiency models. We keep common parts in stock and can source specialized components when needed. Whether you have a basic system or a complex zoned setup, we have the knowledge and tools to diagnose and repair it properly.
Several factors determine whether repair or replacement makes sense: the age of your system, frequency of breakdowns, energy efficiency, and repair costs compared to replacement value. Generally, if your AC is over 10-15 years old and needs major repairs, replacement might be more cost-effective long-term. However, newer systems with minor issues are usually worth repairing. Dempsey Energy will give you an honest assessment based on your specific situation and budget, not what makes us the most money.
Our AC tune-up includes cleaning or replacing air filters, checking refrigerant levels, inspecting electrical connections, cleaning condenser coils, testing system controls, lubricating moving parts, and checking for any signs of wear or potential problems. We’ll also test system performance and efficiency to make sure everything is running optimally. This preventive maintenance helps catch small issues before they become expensive repairs and keeps your system running efficiently, which saves money on energy bills.
Dempsey Energy stands behind our work with warranties on both parts and labor. If the same problem occurs again within the warranty period, we’ll return to address it at no additional charge. We take the time to properly diagnose issues the first time to avoid callbacks, but if something does go wrong, we’ll make it right. Our goal is to build long-term relationships with customers, which means ensuring you’re completely satisfied with every repair job we complete.
