HVAC Naperville IL

Common HVAC problems we see in Naperville include poor airflow from supply vents, thermostat malfunctions, dirty filters, refrigerant leaks, frozen AC coils, and uneven temperatures between floors. Regular maintenance from Eco Temp HVAC can prevent many of these issues and catch small problems before they turn into major repairs.

We recommend scheduling HVAC maintenance twice a year in Naperville—once in the spring for your air conditioner or heat pump, and once in the fall for your furnace or boiler. These seasonal tune-ups help your equipment handle Naperville’s hot summers and cold winters while improving efficiency and reducing the risk of breakdowns.

Naperville residents may qualify for local electric utility rebates on qualifying high-efficiency central air conditioners and air-source heat pumps, as well as state and federal incentives when available.

Naperville’s electric utility has offered incentives for qualifying air-source heat pumps that meet specific efficiency requirements, including some ducted and ductless mini-split systems that serve the whole home. Program details—such as minimum efficiency ratings and whether the system must replace an existing unit— can change over time.

Eco Temp HVAC stays up to date on Naperville heat pump rebates and can let you know if your new heat pump or ductless mini-split is eligible when we design your system.

Signs your furnace may need service include loud or new noises, frequent cycling, rooms that never get warm enough, rising gas or electric bills, and a yellow burner flame instead of blue. Furnaces that are 15 years old or more with frequent repairs are often better replaced with a new high-efficiency unit, especially in a climate like Naperville’s.

Yes. Eco Temp HVAC repairs and replaces boiler systems in Naperville, including baseboard, radiator, and radiant floor setups. If your boiler is leaking, making banging noises, or leaving radiators cold, we can diagnose whether a targeted repair or a new boiler will be the most cost-effective option.

Modern heat pumps can perform very well in Naperville when properly sized and paired with the right backup heat source. Many homeowners use a dual-fuel setup, where a heat pump handles most of the heating and cooling while a gas furnace or boiler only runs on the coldest winter days. We can compare heat pump options with furnace or boiler upgrades for your specific home and budget.

We install high-efficiency furnaces, variable-speed air conditioners, cold-climate heat pumps, and ENERGY STAR®-certified systems, along with smart thermostats and duct upgrades. During your estimate, we can show you which options make the most sense for your Naperville home and which may qualify for rebates or incentives.

An AC blowing warm air can be caused by a refrigerant leak, dirty filters, a blocked outdoor unit, thermostat issues, or a failing compressor. If your air conditioner is not cooling, it is best to shut it off and schedule AC repair so a technician can diagnose the problem and prevent further damage.
