Frequently asked questions

HVAC questions,
answered

This is a complex question that will yield different answers depending on what state you live in, how large your home is (how much heating and cooling capacity you require), and the brand and model in which you are interested. Contact the experts at ARS for professional sizing of your system and help with comparing your options.
We're available 7 days a week and offer same-day and emergency service in most areas. Once you submit your request, a comfort advisor will call to confirm the soonest available appointment window that works for your schedule.
We recommend professional maintenance at least once a year — ideally your cooling system in spring and your heating system in fall. Regular tune-ups keep your system running efficiently, catch small issues before they become costly repairs, and help protect your manufacturer's warranty.
Absolutely. Every ARS technician is licensed, insured, and background-checked, and our work is backed by our one-year Exceptional Service Guarantee — if you're not satisfied, we'll make it right.
