Yes. We run 24/7 emergency service for no-heat and no-cooling calls across Waukesha County and the surrounding communities, with fully stocked trucks for on-the-spot fixes whenever possible. On The Dot Club members go to the front of the line during snow days and heat waves.

Diagnosis first, price before work: the technician runs a full diagnostic, shows you exactly what failed, and gives you the exact cost to fix it before any wrenches turn. We arrive when we say we will — it's in the company name.

Most AC repairs run $150–$2,200+ — capacitors and contactors at the low end, compressors at the high end, with refrigerant-leak and compressor jobs pushing past the top of the range. That's a planning range from our Instant Pricing tool, not a quote; the exact price comes after diagnosis, before any work starts.

Instant Pricing tool →

$6,200–$10,600 installed with permit for SE-Wisconsin homes — 80% AFUE equipment at the low end, 96%+ modulating systems at the high end. A furnace + AC combo replacement runs $5,400–$16,000+. Final pricing always comes from a written quote after an on-site evaluation.

Heating services →

$169 flat. That covers the full inspection, coil check, and refrigerant-level and performance test before cooling season. On The Dot Club members get two seasonal tune-ups (one furnace, one AC) included in the membership.

A single-zone ductless mini-split runs $3,500–$9,500+ installed — basic short-run systems at the low end, premium cold-climate units with long concealed line runs at the high end. Multi-zone systems and panel/electrical work price above that range, and high-efficiency units may qualify for rebates.

Ductless mini-splits →

No. Every published figure is a ballpark planning range — your final price requires an on-site evaluation and a written, signed proposal (Terms §3). Nothing on the site is a binding offer, and no honest contractor can quote a real install without seeing the home.

Terms & Conditions →

Yes — it's a signature On Time offer. Send another HVAC contractor's repair or replacement quote (PDF, photo, or typed) and Shane or an owner-trained tech reviews it line by line for free, no obligation. Plenty of homeowners learn their original contractor was fair and never become customers — that's by design.

Repairs we make are guaranteed for as long as your On The Dot Club membership stays active. If a covered repair fails while you're enrolled, we make it right — that's the point of the club.

Run the numbers yourself: the ROI calculator on the membership page adds up the two included tune-ups at retail price, the repair discount, and the waived service fees, then shows your break-even point. For most homes with equipment past its warranty years, the tune-ups alone cover the membership cost.

Yes — modern cold-climate heat pumps are a real option for SE-Wisconsin homes, most often in a dual-fuel setup: the heat pump handles mild and shoulder-season heating efficiently, and the gas furnace takes over below the economic crossover point (typically around 25–35 °F). Our Heat-Pump-for-Wisconsin calculator runs the honest break-even math for your home and fuel rates.

Short cycling — firing up, running briefly, shutting off, repeating — usually points to an oversized system, a dirty filter, a bad thermostat location, or a deeper control problem. It's hard on equipment, bad for comfort, and worth a diagnostic visit before it takes out an expensive component.

HVAC glossary →

The right size comes from a Manual J room-by-room load calculation, not a rule of thumb — typical SE-Wisconsin homes run 2–4 tons of cooling. Bigger is not better: an oversized system short-cycles, dehumidifies poorly, and wears out early. Our sizing estimator gives you a ballpark range to sanity-check any quote.

HVAC equipment replacement generally requires a mechanical permit from your local building authority before the work starts — and the contractor pulls it, not you. A pulled-and-inspected permit protects your homeowner's insurance, resale value, and manufacturer warranty. The Permit Pilot tool in our Learning Center gives you a quick three-question verdict for your specific job.

Sometimes — and we'll tell you when it isn't. Whole-home source-removal cleaning (all supply and return ducts on one system) runs $300–$1,500+ in our market, and around here sub-$300 specials are usually partial-clean teasers. On The Dot Club members get an annual duct camera inspection included, which is the honest way to know if yours need it.

Air duct cleaning →

Often, yes — Focus on Energy, Wisconsin's statewide efficiency program, offers rebates on qualifying high-efficiency furnaces, ACs, heat pumps, and certain indoor-air-quality upgrades. Programs change through the year, so we confirm exactly which rebates apply to your project when we quote it — never inflated, never invented.

Yes — WI License #1482483 — On Time Heating & Cooling, LLC, and fully insured. We pull the permits for the work we do, and the inspector closes them out.
