It’s easy to schedule an appointment, they follow up with text/phone calls to confirm when the technician will arrive, and the service work by their techs is beyond reproach! Why would you not want this company to be your HVAC go-to guy!”

One HVAC Company for Installation, Maintenance, and Repair
Heating and cooling needs change throughout the life of a system. New equipment needs to be properly installed, existing equipment requires maintenance, and eventually a system may need troubleshooting, repair, or replacement. Working with a company that can handle each of these stages gives property owners one place to turn as their HVAC needs change.
We provide residential, commercial, and industrial heating, cooling, and exhaust system services. Our capabilities range from minor repairs and routine system maintenance to complete new equipment installation. We also work with multiple heating technologies, including furnaces, heat pumps, and geothermal systems, along with cooling equipment and specialized commercial refrigeration systems. A&S HVAC has served the Greater Lehigh Valley and surrounding communities for more than 25 years. That experience allows us to work with a wide range of equipment and property types while helping customers determine which service is appropriate for their current system and situation.
