Heating Installation & Replacement


If you are looking for a forced air furnace, McAlister Mechanical has qualified heating installation specialists to cover all your needs and answer all of your questions. We can help you choose a new model be it standard or high efficiency or install what you have already purchased.

Our experienced heating installation technicians can help you design the most efficient and comfortable heating system within you budget. McAlister technicians are up to date on the latest technology in the HVAC industry and will informatively help you through the evaluation process which can be overwhelming. As we do not sell direct to customers, we offer our honest opinion based on your unique situation.

If your existing system is old, needing repair or costly to operate, consider replacing your current system with a new unit. New units can be as much as 60% more efficient than a system purchased just 10 years ago, can offer long-term cost and reliablility benefits. Qualified McAlister heating installation professionals can help you determine an appropriate size for your new heating system by running heat requirement calculations. Systems that are too small will fail to keep your home or business at a comfortable temperature and will often compromise the system itself due to overuse. Systems to large will be inefficient and costly to operate. Often system efficiency can be drastically increased by updating the thermostat. Our trained heating installers will fully understand the control system and happily make sure you understand how to use the thermostat efficiently.


When replacing an existing system home owners often choose a new unit with equal or higher efficiency ratings compared to their previous system. Replacing a unit that is 10- to 15-years-old with a new highly efficient system may reduce natural gas or electricity costs by 30 to 50%. When replacing an existing central forced air system McAlister Mechanical’s heating installation technicians will inspect the property’s ductwork, insulation, electrical service, wiring, thermostat, flue piping, flue terminations, chimney liner, filters and much more.

If converting to a forced air system in a home or business that has not had central heat before requires the installation of duct-work. Duct-work is composed of two parts, supply and return. Supply duct-work delivers air to each room in a home. Return ducts draw air out of the rooms to be heated and filtered, which occurs at the furnace.
