Sub Zero Cooling & Heating - Lebanon's Trusted HVAC Services

These are common local HVAC issues. A boiler losing pressure often indicates a leak in the system or a faulty pressure relief valve, while warm air from your AC frequently points to a refrigerant leak. For Lebanon homeowners, we diagnose these problems directly at your home. Our EPA-certified technicians use specialized tools to locate leaks, whether in your boiler's piping or your AC's refrigerant lines, and provide clear repair options to restore proper operation and efficiency.

The decision depends on the age of your system, frequency of repairs, and energy efficiency. We provide honest assessments for Lebanon residents. If your system is over 15 years old, requires frequent costly repairs, or causes high energy bills, a replacement may be the more cost-effective long-term solution. We'll explain all factors, including potential rebates and financing, to help you make an informed choice for your home and budget.

Yes, we do. With over 25 years of experience, our technicians are trained to work on all major HVAC brands, whether it's for installation, repair, or maintenance. We provide expert service for your existing system or can help you select and install a new unit that best fits your Lebanon home's specific needs and layout, ensuring compatibility and optimal performance.
