Lennox Fall 2026 Promotion: Up to $1,800 in Rebates on a Lennox Ultimate Comfort System

Questions and answers

How much is the Lennox rebate in the fall 2026 promotion?

Up to $1,800 on a new Lennox Ultimate Comfort System when you take the rebate on its own: a system rebate from Lennox’s rebate matrix (up to $1,500 for a qualifying indoor unit, outdoor unit and thermostat) plus eligible system add-ons such as the S40 Smart Thermostat, PureAir S and Smart Zoning, up to $1,800 combined. If you would rather combine a rebate with Lennox’s 60-month no-interest financing, the rebate is up to $1,400 combined (system rebate up to $1,200 plus eligible add-ons). The exact amount depends on the models installed together; a SL22KLV heat pump or SL25KCV air conditioner with an SLP99VK furnace earns the top $1,500 system rebate, and your written estimate shows the figure for your equipment.

What are the dates?

Purchase between September 14, 2026 and December 4, 2026, with installation completed by December 11, 2026. The rebate claim must be submitted online by January 10, 2027 at 11:59:59 p.m. Eastern.

How is the Lennox rebate paid?

As a Lennox Prepaid Mastercard. After installation, the claim is filed at lennoxconsumerrebates.com with GSHA’s invoice listing every model and serial number. GSHA gives you that invoice and can walk you through the claim; approved rebates arrive as a virtual card or a physical card in the mail.

Which Lennox systems qualify, and is a thermostat required?

System rebates need a qualifying Lennox indoor unit, a qualifying outdoor unit and a qualifying thermostat installed together. Qualifying thermostats are the Lennox S40, E40, M40 and L40, or a Honeywell programmable, Braeburn programmable or Ecobee thermostat purchased through Lennox. Add-ons such as the S40, PureAir, Smart Zoning, the Smart Air Quality Monitor, an HRV or ERV and MERV 16 filters increase the rebate when bought with the system but do not earn a rebate on their own. Replacing a single piece of equipment earns a smaller individual rebate instead.

Is GSHA a participating Lennox dealer?

Yes. GSHA Services, LTD is listed as a Lennox Premier Dealer on Lennox’s dealer locator and participates in the Lennox fall 2026 consumer promotion for homes in our Illinois service area.

Can the rebate be combined with financing?

Yes, in one of two ways. Take the higher rebate (up to $1,800) without the promotional financing, or take financing (equal monthly payments, no interest for 60 months for qualified buyers) with the higher rebate replaced by a rebate of up to $1,400. Either way the financing is subject to credit approval and the terms below. Lennox’s fall offer includes promotional financing for qualified buyers: equal monthly payments with no interest for 60 months (the promotion period), subject to credit review and approval; minimum loan amounts range from $500 to $3,000 depending on the plan, and not all applicants qualify. If the financed amount is not paid in full before the promotion period ends, or a payment is 31 days or more late, the promotional terms are void and the remaining balance accrues interest at an APR of 2.99% to 25% depending on state, amount, term and credit profile, repaid over 36 to 60 months. Complete terms and Truth in Lending disclosures are in the retail installment contract. Financing programs available through GSHA are on our financing page; ask your comfort advisor which option applies before you sign.

What about ComEd or Nicor Gas rebates?

Lennox rebates are separate from any ComEd or Nicor Gas rebate. Utility rebates depend on your utility, the equipment installed and the installation date, and we check current eligibility during the estimate.

What does the free estimate include?

A GSHA comfort advisor measures the home, checks the existing equipment, ductwork, venting, gas and electrical, and gives you a written quote for a matched Lennox system with the promotion rebate shown.
