Replacement estimates, in writing

About 45 minutes in your home, then a written proposal the same day with two or three options and the price, warranty and rebate for each. No pressure, no expiring-today tactics.

Flat-rate

Repairs with no sticker shock

We charge by the job, not by the hour. You approve the exact price before a tool comes off the truck, the price does not change if the job takes longer than we thought, and the repair is guaranteed for one year, parts and labor.

We will give you our own written replacement estimate, free. If we think a repair makes more sense than a new system, we will tell you.

Offers apply to residential work in Milwaukee and Waukesha counties and cannot be combined with each other. They have no set expiration date; if an offer changes, this page changes with it, and the price on your written proposal is the price you pay.

Discounts and rebates that stack on top

Focus on Energy, Wisconsin’s statewide efficiency program, offers instant discounts on qualifying high-efficiency gas furnaces, boilers, heat pumps, water heaters and smart thermostats: participating distributors pay them and the contractor passes them through, so the discount comes off the invoice. Income-qualified households may also qualify for the state’s IRA Home Energy Rebates, which mostly require an IRA Registered Contractor, so ask before you sign. We tell you what your equipment qualifies for before you buy.

Good to know

Frequently asked questions

Can I combine offers?

One offer per job. The $1,000 bundle discount already includes the furnace and AC savings. Financing and rebates can be used with any offer.

Do the offers expire?

No set end date. These are everyday offers, not a countdown. If one ever changes, this page will say so, and whatever we put on your written proposal is the price you pay.

Is the $89 tune-up really a full service?

Yes. It is the same inspection we do on every maintenance visit, with a written report. If we find something that needs repair, you get a flat-rate price and decide; nothing is done without your approval.

“Called on a Saturday and they gave me a time. We were able to get our furnace going ourselves. We called and canceled and he said that is fine and asked what we did. He told us he would have done the same.”
