Choose the System That Works Best For You
Ductless Mini Split Installation
Mini splits are one of the most flexible and energy-conscious ways to cool your home. If your property doesn’t have ductwork, or if you’re only looking to cool certain rooms, mini splits offer an option that does NOT require invasive construction or bulky retrofitting. Each wall-mounted indoor unit connects to a quiet outdoor compressor, giving you control over each room’s temperature and helping you avoid wasted energy. We install single-zone and multi-zone systems depending on the layout of your space and your long-term goals.
Homes with additions, sunrooms, or converted garages are especially good candidates for ductless cooling. We’ve also seen more homeowners in older homes choosing mini splits as a clean and cost-effective alternative to window units or through-the-wall systems. If you’re unsure whether your home is a good fit, we’re happy to take a look and walk you through your options.
Central Air Conditioning Installation
If you’re looking for a whole-home solution with consistent airflow and temperature control, central air conditioning remains a popular choice throughout our service area. Central AC offers powerful, even cooling through an existing or newly installed duct system. It also integrates easily with air purification and dehumidifying systems if you want cleaner indoor air along with better comfort.
We install high-efficiency systems from trusted brands that have SEER2 ratings in order to meet today’s energy guidelines. Your monthly utility bills will stay manageable even during long stretches of heat. For homes undergoing a renovation or for new construction projects, we can size and design the full system, coordinate closely with other trades, and keep the schedule moving forward.
Heat Pump Cooling & Combined Systems
Heat pumps have quickly become a smart way to handle both cooling and heating from a single piece of equipment. During the summer, they cool your home just like a traditional AC system. When cooler months arrive, they reverse direction and pull in heat from the outside air, even in New England’s colder climate. The technology is remarkable.
Heat pump installation can also be a great add-on to existing ducted AC systems. In many cases, we can retrofit your current setup with a heat-ready coil so that you can use it for heating during spring and fall, or even throughout the winter depending on the model. We work directly with homeowners and contractors to help you decide whether a ducted, ductless, or hybrid solution will give you the best value.
When Should You Replace Your Cooling System?
It’s worth considering a new installation if your current system is more than 12–15 years old, especially if it struggles to keep up on hot days, makes unusual noises, or causes sudden spikes in your electric bill. Replacing an old unit with a modern, energy-efficient system can save you money over time and prevent the inconvenience of breakdowns in the middle of summer.
In homes without any current cooling system (or in new construction) it makes sense to start fresh with a design that fits your square footage, insulation, and duct layout. Reliant Plumbing & Heating can handle the entire installation process and provide system recommendations based on real-world performance and the layout of your home.
