A successful oil to gas conversion in Hicksville starts long before the first piece of equipment arrives. Our installation process begins with an in-home evaluation where we assess your property's specific requirements, taking into account the characteristics of post-war ranch and Cape Cod homes from the 1950s with original ducted heating systems. We perform Manual J load calculations to determine the exact heating and cooling capacity your home needs, factoring in insulation levels, window types, sun exposure, and the layout of your living space.
Once your new system is installed, our team conducts a complete commissioning process. This includes verifying refrigerant charges, testing all safety controls, calibrating thermostats, and measuring airflow at each register.

Our technicians share these practical recommendations based on years of experience servicing post-war ranch and Cape Cod homes from the 1950s with original ducted heating systems throughout the 11801 area. Following these tips helps Hicksville homeowners extend equipment life and reduce energy costs.
Schedule your annual heating maintenance before October to avoid the winter rush. Hicksville homeowners who tune up early save an average of 15-25% on winter heating bills.
Change your air filter every 1-3 months during heating season. Homes with post-war ranch and Cape Cod homes from the 1950s with original ducted heating systems often accumulate more dust and debris, which restricts airflow and forces your system to work harder.
Keep vents and radiators clear of furniture, curtains, and storage items. Blocked airflow is one of the most common causes of uneven heating in Hicksville homes.
Set your thermostat to 68°F when you're home and 60-62°F when sleeping or away. A programmable or smart thermostat can automate these adjustments and reduce your annual heating costs significantly.
