Why people are calling us
If your AC is breaking down every season, struggling on the hottest days, or costing more to run than it should — replacing it is usually cheaper than another year of patches. Here's how Tempco handles it.
A Tempco tech walks through your system and tells you what's actually failing — and what isn't. We don't push replacements people don't need.
We size the system to your home, not to what's on the truck. Wrong-sized AC is the #1 reason new installs disappoint.
You get a clear estimate before we start. The price you sign is the price you pay.
What we do
From honest assessment to clean install, Tempco handles every step. Across Nassau and the North Shore.
What makes us different
Tempco was founded on Long Island in 1985 and is still owned and run by the same family. When you call us, you're working with the people whose name is on the door — not a sales rep on commission.
Call 516-674-5100 and a person picks up — usually on the first or second ring.
We work with PSE&G and partner with major financing programs so a new AC doesn't have to mean draining your savings.
We install Rheem and other top-tier systems with proper sizing and clean install practices. A new AC should last decades — we install it that way.
If your system is down, call us — we run 24/7 emergency service across Nassau and the North Shore.
