Air conditioning systems are crucial for maintaining comfortable indoor temperatures during hot weather. These systems use pressurized coolant to cool and circulate air, providing comfort even on the hottest days. At James A. Dalelis Plumbing & HVAC, we offer an extensive selection of AC units designed for homes and businesses of all sizes. Our technicians perform precise measurements to recommend systems that maximize cooling efficiency and minimize energy costs.
Heat pumps are efficient, all-in-one HVAC solutions for heating and cooling needs. Consisting of an indoor air handler and outdoor unit, heat pumps use refrigerant lines to capture and transfer heat in or out of your home depending on the season. This energy-saving heating and cooling method makes heat pumps an excellent option for eco-conscious homeowners seeking year-round comfort.
Furnaces deliver powerful heating, especially during colder months. Using natural gas or propane, furnaces burn fuel to generate warm air that's then distributed throughout your home. Stan's can evaluate your home's size and heating requirements to recommend a furnace with the proper capacity to keep your living space warm and comfortable. Our team installs furnaces to ensure safe, effective operation for dependable heat all winter long.
Mini split systems are compact, ductless units ideal for cooling, heating, or cooling specific rooms or areas. Perfect for spaces not covered by a central HVAC system, mini splits allow you to control the temperature of individual rooms without extensive ductwork. They're also ideal for additions, garages, or renovations with unique needs, or for homes where one room requires a different temperature than the rest.
Choosing the right thermostat can dramatically enhance your HVAC system's performance. Stan's installs a range of popular thermostats, including Honeywell, Nest, and Ecobee, with options for programmable models that allow you to control your home's temperature remotely. Whether you're home or away, a quality thermostat helps you maintain a comfortable environment while optimizing energy use.

Fast, efficient, and professional. I went to turn my heat on and realized my boiler wasn’t working. It was a Friday before a long holiday weekend but James had one of his guys there first thing Monday morning and my heat was back up and running in just a few hours! Thank you so much!! Highly recommend
Met with me on short notice and took the time to talk about all options, but brief and to the point.
Helped me make a better decision.
Went above and beyond so the work got done in a timely manor and we're very satisfied with the results.
Thank you, James & Crew.
Excellent service. Responded quickly to confirm my appointment and the work was completed quickly the same day. We will be using this company for our yearly heating maintenance.
I had a great experience working with James and his team to install our new boiler and water heater. He worked to understand our needs, gave us solid advice, and provided a competitive bid with no extras or upsells (and no BS!). His work was very professionally done, and it was obvious that he took great pride in his work and in providing the most useful components. He also took the time to explain the work, how the equipment worked, and made sure the settings were what we we were looking for. All in all a great experience, and we will be working with him again.
If your HVAC system is over ten years old, frequently requires repairs, or isn't cooling and heating efficiently, it may be time to consider a new unit. Replacing it can be more cost-effective than ongoing repairs, especially if it's outdated and impacting energy costs.
Installing a new HVAC unit can improve your home's comfort and energy efficiency. Newer models often use less energy, which can lower utility bills, and may qualify for manufacturer or utility rebates, adding to the overall savings.
Professional installation ensures that your HVAC system is set up to operate at maximum efficiency and reliability. A skilled technician will correctly size and install the unit, optimize airflow, and ensure proper ductwork connections, which reduces energy waste and prolongs the life of your system. This ultimately saves you on energy bills and repair costs over time.
Selecting the right HVAC system depends on your home's size, energy needs, and your budget. Factors like insulation, climate, and your preferred comfort level also play a role. At James A. Dalelis Plumbing & HVAC, our expert technicians can assess your home and recommend the best system to meet your comfort and efficiency goals, ensuring you get the most value for your investment.
Regular maintenance is key to keeping your HVAC system running smoothly. This includes annual inspections, changing filters every 1-3 months, and cleaning the system to prevent dust buildup. Routine maintenance helps the system work more efficiently, extends its lifespan, and ensures optimal performance.
