Which systems does the HVAC calculator widget cover?

Central AC, heat pumps, furnaces and combined systems, sized by square footage and efficiency tier with 2026 prices.

Does the HVAC widget slow down the embedding website?

Is a developer needed to install the HVAC calculator widget?

No — one snippet pasted into a Custom HTML block is enough; the height adjusts automatically.

HVAC Replacement Cost Calculator Widget — Free Embed

An HVAC replacement is a distress purchase: the AC died in July and the homeowner is googling prices at midnight. If your website answers “what will this cost me?” right there — by system type, home size and efficiency tier — that 2 a.m. visitor becomes your morning phone call instead of a lead-portal entry sold to three competitors.

Made for

HVAC contractors: Price transparency is rare in this trade — which is exactly why it converts. A visitor who got an honest range from your site trusts your quote more than the competitor's “call for pricing”.
Home services companies: Bundle it with your maintenance-plan pages: the replacement estimate makes the case for keeping the current system alive — your service plan.
Home inspection & energy audit sites: Give report readers an instant budget for the aging furnace you just flagged.

Frequently asked questions

Which systems does the calculator cover?

Central AC, heat pumps, furnaces and combined systems, sized by home square footage and efficiency tier (standard to high-SEER), with 2026 equipment and installation prices.

Will the widget slow my site down?

No — it loads lazily (only when scrolled into view) inside an isolated iframe, so it doesn't touch your page's scripts, styles or Core Web Vitals during initial load.

Do I need a developer to install it?

If you can paste text, you can install it: one snippet into a Custom HTML block. Height adjusts automatically on phones and desktops. Platform-by-platform instructions are in the embed guide.
