Dempsey Energy has been serving Quincy families since 2001, building relationships with over 12,000 customers who count on us when their AC systems fail. We’re not the fly-by-night contractors who show up unprepared.
Our family-owned business understands Quincy’s unique climate challenges—from the humid summers that strain condenser units to the aging ductwork in historic neighborhoods like Wollaston and Merrymount. We know which equipment performs best here and how to maintain systems for maximum efficiency.
When you call us, you’re working with technicians who live and work in Norfolk County. We understand what Quincy homeowners face, and we show up prepared to solve it.
First, you call and we listen to what’s happening with your system. We schedule a time that works for you—often the same day for urgent repairs.
Our technician arrives with diagnostic tools and the parts needed for most common repairs. We start with a thorough diagnostic to identify the root cause, not just the symptoms. No guessing, no multiple trips for basic problems.
You get an upfront explanation of what’s wrong and what it costs to fix before any work begins. After we complete the repair, we test everything to make sure it’s working properly and clean up our work area. Our follow-up system tracks your service history and sends maintenance reminders so your system keeps running smoothly long-term.

Our AC repair services cover everything from minor tune-ups to major component replacements. We handle refrigerant leaks, compressor issues, thermostat malfunctions, and electrical problems that commonly affect systems in Quincy’s coastal climate.
Quincy’s older homes—many dating back to the 19th and early 20th centuries—often have aging ductwork that requires specialized attention. We understand these unique challenges and come prepared with solutions that work for both historic properties and newer builds in areas like Marina Bay.
Massachusetts weather puts extra stress on HVAC systems with cold winters and humid summers. Our technicians know which components fail most often in this climate and carry the right parts to fix them. Whether your system is under 10 years old and needs fine-tuning or over 15 years old requiring component replacement, we have the expertise to keep it running efficiently.
We prioritize emergency AC repairs during heat waves and typically respond the same day for urgent calls. Our technicians carry diagnostic tools and common parts for the most popular AC brands, which means faster repairs in most cases.
During peak summer months when temperatures hit 82°F or higher, we understand that AC failures aren’t just inconvenient—they’re potentially dangerous, especially for elderly residents or families with young children. Our fully stocked trucks allow us to complete most repairs on the first visit without waiting for parts to be ordered.
If your AC completely fails during extreme heat, we’ll work to get you some level of cooling restored quickly, even if the full repair takes additional time. Our goal is to never leave a Quincy family without relief during dangerous heat conditions.
Quincy’s high summer humidity—often climbing above 70%—puts extra strain on condenser units and coils, leading to more frequent refrigerant issues and component failures. The salt air from our coastal location can also accelerate corrosion on outdoor units.
We see frequent problems with dirty air filters causing weak airflow, especially during humid months when systems work harder to remove moisture from the air. Thermostat issues are also common when humidity levels fluctuate dramatically between seasons.
Older Quincy homes often have ductwork challenges that affect system performance. Poor insulation or aging ducts can cause uneven cooling and force your AC to work harder than necessary. Our technicians are experienced with these local issues and know how to address them effectively without unnecessary system replacements.
Yes, we provide 24/7 emergency AC repair service throughout Quincy. AC systems don’t break down on convenient schedules, and we understand that some situations can’t wait until regular business hours.
Our emergency service covers situations like complete system failures during heat waves, electrical issues that could be safety hazards, or refrigerant leaks that need immediate attention. We respond quickly because we know how uncomfortable and potentially dangerous it can be when your AC fails during extreme weather.
Emergency service calls do carry additional fees compared to regular appointments, but we’re transparent about pricing upfront. Our technicians come prepared with common parts and diagnostic equipment, so even emergency calls can often be resolved the same day rather than requiring multiple visits.
Generally, if your AC system is over 10-12 years old and facing major component failures, replacement often makes more financial sense than expensive repairs. We look at factors like repair cost versus remaining system life, energy efficiency of your current equipment, and frequency of recent repairs.
Signs that repair makes sense include minor issues like dirty filters, thermostat problems, or refrigerant top-offs on newer systems. But if you’re facing compressor failure, major electrical issues, or multiple component problems on an older unit, replacement typically provides better long-term value.
We’ll give you honest recommendations about repair versus replacement based on your specific situation and budget. Our goal isn’t to sell you the most expensive option—it’s to provide solutions that make sense for your home and financial situation. We’ll explain the pros and cons of each approach so you can make an informed decision.
Yes, as a Mass Save partner, we help Quincy homeowners access valuable rebates and tax incentives for energy-efficient AC upgrades and replacements. Massachusetts offers some of the best incentives in the country for upgrading to high-efficiency systems.
We stay up-to-date on current rebate opportunities and can guide you through the application process. Many of our customers are surprised to learn how much money is available to offset the cost of new, efficient equipment. These programs can make upgrading more affordable than continuing to repair an old, inefficient system.
We also offer financing options to help spread the cost of larger repairs or replacements over manageable monthly payments. Our goal is to ensure that budget constraints don’t force you to live with an unreliable AC system or delay necessary repairs that could prevent bigger problems down the road.
In Quincy’s humid climate, changing your air filter every 1-3 months is crucial—dirty filters are one of the most common causes of weak airflow and system strain. During peak summer months when humidity is high, filters can clog faster than in drier climates.
Keep your outdoor condenser unit clear of debris, leaves, and vegetation. Salt air and coastal moisture can cause buildup on coils, so gentle cleaning with a hose can help maintain efficiency. However, avoid using pressure washers or harsh chemicals that can damage delicate fins.
Schedule professional maintenance at least once a year, ideally in late spring before peak cooling season. Massachusetts weather puts extra stress on HVAC systems, so regular professional inspections help catch small problems before they become expensive repairs. Our Dempsey Comfort Club members get priority service and comprehensive maintenance that includes refrigerant level checks, safety control testing, and component cleaning.
