Who We Are

Committed to Excellence

Doty Mechanical is a locally owned and operated customer-focused Heating and Air-Conditioning company that has been proudly serving the Greater Lansing area for over 40 years. The founders and original owners of A-1 Mechanical sold the company and later re-opened their doors as Doty Mechanical at the encouragement of former customers, employees, and business associates. Doty Mechanical’s current owners and employees remain committed to maintaining the heritage and vision of the founders.

Our highly trained team is dedicated to making Doty Mechanical the best Heating and Air-Conditioning company in Lansing & Mid-Michigan, including Ingham, Eaton, and Clinton Counties, while honoring the traditions and values that have made our company successful. We understand the importance of delivering exceptional service to our customers and we strive to exceed their expectations with every interaction.

We are so confident in the quality of our work that we offer a 100% satisfaction guarantee and a 10-year No Worries labor warranty. We look forward to serving our customers and ensuring their complete satisfaction.

100% Satisfaction Guarantee

As a Carrier Factory Authorized Dealer, when Doty Mechanical installs a new Carrier Furnace, Air Source Heat Pump or Air Conditioner, your equipment and installation is covered by a Carrier Corporation backed 100% Satisfaction Guarantee. If for any reason you are dissatisfied with your Carrier equipment or installation, Doty Mechanical and Carrier Corporation will make every attempt to resolve your concerns. If we fail to resolve those concerns, Doty Mechanical will come out and remove the equipment we installed and issue a refund to you.

Lifetime Workmanship Guarantee

We take pride in our commitment to providing top-quality HVAC (Heating, Ventilation, and Air Conditioning) services to our valued customers. We are dedicated to ensuring your complete satisfaction with our installation work. To demonstrate our confidence in the skill and expertise of our technicians, we provide a Lifetime Workmanship Guarantee covering defects in workmanship that may arise as a result of our installation services.

This guarantee does not cover repairs due to mechanical failure, lack of maintenance, or homeowner error.

Take a look at how our guarantees stack up against the restrictive fine print and exclusions often utilized by other companies in the industry. While many may only guarantee that the equipment will function properly, we go above and beyond by ensuring your satisfaction throughout the entire process, and most importantly, the final outcome. It’s this unwavering commitment to our customers that has led to our continued growth and a high rate of satisfied home and business owners year after year. Get in touch with Doty Mechanical today for your service needs and discover what you’ve been missing out on.
