Air Conditioning — common questions

How long does an HVAC system last in our climate?

In the Chicago area, most furnaces last 15–20 years and air conditioners 12–18 years, depending on use and maintenance. Once a system passes that range or needs frequent repairs, we'll walk you through repair-vs-replace as if it were our own home.

What is R-454B, and why does it matter for a new system?

R-454B is the lower-global-warming refrigerant that replaced R-410A in new air conditioners and heat pumps as part of the 2025 transition. We install current-standard equipment so your investment stays compliant and serviceable — and because it's a mildly flammable (A2L) refrigerant, a properly trained, permitted install matters more than ever.

How often should I schedule maintenance?

We recommend two visits a year — a spring tune-up for your AC and a fall tune-up for your heating system. Seasonal maintenance keeps efficiency high, catches small issues early, and protects your manufacturer warranty.

Should I repair or replace my furnace or AC?

It depends on the system's age, the cost of the repair versus a replacement, and how long you'll stay in the home. Our rule is the “our own home” test — we'll tell you which option makes sense, and we'll never push a replacement when a fair repair will do.

What does a new furnace or AC cost?

It varies widely — the equipment is only part of the job. Your home's size, ductwork, efficiency level, and what's behind the walls all move the number, so any exact price quoted sight-unseen is a guess. We give you one upfront flat rate after seeing your home.
