Local Air Conditioning Company Services
Consistent home cooling and broader HVAC support across Norfolk, Bristol, and Plymouth County since expanding our services in 2001.

If your current system struggles, makes odd sounds, or fails, it impacts your family’s well-being.

AC System Installation Details
Our Approach to New AC Systems
Installing a new air conditioning system correctly is foundational , whether you reside in Norfolk or neighboring Bristol County towns. Firstly, one of our home comfort advisors helps determine the appropriate system type (ie. central air or ductless splits) and size using careful load calculations specific to your home’s layout and features, preventing errors linked to improperly sized units. We then proceed with the physical installation, setting up the outdoor condenser and indoor components.
For central air systems, this involves connecting refrigerant lines using quality copper tubing, linking to existing or new ductwork, and wiring thermostats. Perhaps recommending smart thermostat options for control. Our NATE-certified air conditioning contractor will manage the electrical hookups and verify the correct refrigerant charge (usually R-410A). As a local ac air conditioning company in your area, we prioritize executing the setup using high-quality parts for dependable operation from the start.
AC System Maintenance Importance
Maintain Your Cool with Annual Upkeep
Regular air conditioner maintenance is a practical step to avoid inconvenience, especially before Plymouth County summers set in. Our annual tune-ups involve cleaning coils, checking refrigerant levels, inspecting electrical parts, and changing filters – tasks that upscale your AC performance. Joining our maintenance plan offers set pricing (starting points vary by system type, e.g., Central AC & Gas Heat from $488.29/year) and gives you a 10% reduction on parts and labor for any needed repairs during the year.
Furthermore, knowing help is available anytime provides reassurance; that’s why we offer 24/7 emergency services. We also extend appreciation discounts (5%) to veterans, seniors, and first responders (police, fire, EMTs, nurses/doctors). Investing in maintenance through a trusted air conditioner contractor like Dempsey Energy helps protect your system and your budget, keeping your family at ease.
