Can Rexroad work on my furnace or air conditioner?

We currently service most brands of residential furnaces, air conditioners, heat pumps, air handlers, oil furnaces, and packaged units. Service appointments can be scheduled on weekdays between 7:30AM and 2:30PM (excluding holidays), and our on call technician can assist if you are in need of emergency service.

We generally do not service boilers, fireplaces, commercial HVAC units, or HVAC equipment specialized for use in mobile homes.


What can I do to avoid a service call?

Keeping furnace filters clean is the most important step homeowners can take to prevent service calls and premature failure of HVAC systems. Check out our Furnace Filters flyer below for more information on why clean furnace filters are crucial for normal operation and what furnace filters are best to prevent system failure.

If your HVAC system is not heating or cooling enough, check your thermostat settings to ensure that it is programmed to operate how you want it to. Some programmable and learning thermostats have energy saving settings that may keep your home at a set temperature range that is higher or lower than preferred.

Resetting the breakers for the furnace and/ or air conditioner can sometimes get an inoperative unit running again. However, because the cause of system failure can vary in this situation, we recommend scheduling a service call to inspect the system for potential problems even if the system is running again after resetting the breakers.

For gas furnaces, make sure that the gas valve is turned on when starting up the furnace at the onset of cold weather. In freezing temperatures, check the intake and exhaust pipes for the furnace and knock off any ice that could be preventing normal operation.


Does my HVAC system need regular maintenance?

Regular maintenance can help ensure that your HVAC system will operate as intended when you need it most. We recommend scheduling maintenance services in Spring and Fall before extreme weather arrives, though air conditioning inspections may need to wait until it is warm enough for technicians to measure refrigerant levels.

Maintenance and inspection services vary based on the type of HVAC system and any additional equipment such as humidifiers, but typically include inspection of critical system components and cleaning of parts such as flame sensors that may get dirty over time. Our technicians do their best to come prepared with any supplies your system may need for a maintenance service, such as oil furnace nozzles and humidifier pads. See our Maintenance Agreement flyer below for more information on our current maintenance plans and a list of common checks done during maintenance services.
