Which Lennox Systems Qualify for the Maximum Rebate?
The maximum rebate is available on a qualifying Lennox Ultimate Comfort System™. These two pairings reach the top tier.
Heat Pump + Gas Furnace
A dual-fuel pairing that runs on the efficient heat pump in milder weather and switches to gas heat when Michigan turns brutal.
Air Conditioner + Gas Furnace
Lennox's most precise variable-capacity cooling matched to a 99% AFUE variable-capacity furnace — the classic maximum-comfort pairing.
A qualifying thermostat is also required.
Do Other Lennox Systems Qualify?
Yes. Other Lennox furnaces, air conditioners, heat pumps, air handlers, thermostats and indoor air quality products may qualify for lower rebate amounts. Not every indoor and outdoor unit can be paired, and your final rebate depends on the approved combination, thermostat, eligible add-ons and savings option you choose.

Fall 2026 Lennox Offer Terms
Qualifying Lennox equipment must be purchased through 911 Mechanical between September 14 and December 4, 2026, and installed by December 11, 2026. Rebate and applicable financing claims must be submitted by January 10, 2027.
The promotion applies to qualifying residential installations in single-family homes. Rebate amounts depend on the qualifying indoor unit, outdoor unit, thermostat, eligible add-ons, and selected savings option.
The maximum $1,800 rebate cannot be combined with promotional financing. Qualified buyers who select eligible promotional financing may instead combine financing with a reduced rebate of up to $1,400.
Rebates are issued as a physical or virtual Lennox Prepaid Mastercard® following claim approval. The card is valid for 12 months from its date of issue.
Promotional financing is provided through Service Finance Company and is subject to credit review and approval. Not all applicants will qualify. Minimum loan amounts range from $500 to $3,000, depending on the financing offer.
Under the 60-month promotional offer, qualified buyers receive equal monthly payments with no interest during the promotional period. There is no penalty for prepayment.
If the financed amount is not paid in full before the promotional period expires, or if a scheduled monthly payment becomes 31 or more days past due, the promotional terms will become void. The remaining unpaid balance may then accrue interest at an APR ranging from 2.99% to 25%, depending on the applicant's state, financed amount, term length, and credit profile.
Five-year parts and labor protection is available with qualifying system upgrades installed by 911 Mechanical and is subject to applicable equipment, registration, maintenance, coverage, and eligibility requirements.
This offer cannot be combined with another Lennox consumer promotion. Equipment availability and eligible system combinations may vary.
