Furnace Installation on Long Island

If your old heating system is struggling or over 10 years old, you should consider getting it replaced. Todays high-efficiency furnaces will save you money and time over the course of the life of your furnace. Give us a call for an appointment, and well make sure that you have the perfect heating system for your Long Island home installed professionally.

Heating Assessment of Your Home

After you call us out to your Long Island home, our trained professional staff will perform a thorough assessment, considering a range of factors related to your homes potential heating needs. Its more than a measure of your homes total square footage; it’ll include an inventory of your doors and windows, the insulation of your home, the existing ductwork, and other ways your home is affected by the cold winters we get here.

We also perform a heat loss calculation and a load calculation that helps us to understand your homes overall heating needs. We will give you a recommendation for your new heating system based on our years of experience providing HVAC services. Well give you some options regarding the equipment we think youll need to keep your house warm efficiently for years to come based on the British Thermal Units (BTU). Furnaces that are too small are going to struggle to keep you warm, and one thats too powerful is going to decrease efficiency and reduce the lifespan of the furnace. We want to make sure you have the right fit for your home.

Installing Your New Furnace

After we safely remove your old furnace, well start clearing the way for your new one. Most furnaces that we replace have different dimensions from the new, higher efficiency furnaces. We will have already evaluated the measurements and fitting before we arrive for the installation. We will be prepared for most contingencies when it comes to fitting your new furnace snugly in place and tightly connected to the existing ductwork system. If you are replacing a natural gas furnace, well get it hooked up to your natural gas line using high safety standards. After your furnace is in place and connected to the ductwork, well integrate your new furnace with your electrical system to get it powered up. With a combination of our experience and technical expertise, your furnace will start producing heat to warm your home. Well make sure we meet the local codes and regulations while ensuring your preferences are accommodated by your new furnace.

Inspect, Test, and Calibrate Your New Heating System

Once we have the furnace operating, our work continues as we inspect and evaluate the entire system. Well check for gas leaks, proper ignition system operation, thermostat calibrations, and check that the hot air flow is distributed evenly throughout the house. If we installed a new thermostat, well make sure that its working correctly and that you are comfortable with its overall operation.

Before We Leave Your Home

After our HVAC professionals deem the system running efficiently and safely, we will talk to you about the operation and maintenance of your new heating system. If it needs a filter, well let you know how often it needs to be changed to run efficiently. Well also let you know about any other routine maintenance you can do that will keep your system running smoothly during the cold days of winter. Lastly, well clean up after ourselves so thoroughly youll never know we were there, except for that warm flow of air running throughout your home.
