For over 40 years Doty Mechanical has been providing quality heating and cooling installation, maintenance and repair service to the Lansing area. As Lansing's only locally owned and operated Carrier Factory Authorized Dealer, Doty Mechanical is committed to Lansing and the people that live here. We are dedicated to offering the exceptional service our customers deserve. That is why our technicians are NATE Certified (which goes way beyond being factory trained). We can repair your furnace or air conditioner regardless of brand, or if you are ready to purchase a new one, we will happily provide you with a FREE ESTIMATE! Our customers are a huge part of our past and, more importantly, our future success. If you are new to Doty Mechanical again we say welcome, if you are a current customer we thank you for your continued patronage.
"This company was recommended to us by several people. Unfortunately, over about 1.5 years of having them perform various services on our home (replacing the furnace, working on the in-ground heating and also repairing some drains in the garage) we are left worse off and thousands of dollars spent with poor outcomes. The furnace was installed improperly which caused an issue when the A/C was used the following spring which resulted in water damage to our basement. This went on multiple times and had to call the company out multiple times before they finally corrected it. The drains that were "fixed" still leak water. The in-ground heating was repaired but they did not have a correct valve part. Once this was finally re-installed the person installing it did not know how to work the system or show us how to use it. We are now calling out someone again on a Saturday to try and figure out the problem. Not a good company"

Heat pumps rely on evaporation and condensation processes. The unit transfers heat through the system via a compressed refrigerant. The compressor within the pump circulates the refrigerant through two coils. The first coil evaporates the refrigerant and absorbs warmth from the air. The refrigerant then passes to the second coil, where it condenses, and the unit releases the absorbed heat.
A well-installed and well-maintained heat pump lasts an average of 12 to 20 years. Routine filter changes, annual tune‑ups, and prompt repairs help the equipment reach the upper end of that range, while skipped maintenance or poor installation can shorten its life and raise long‑term costs. Ask your heat pump installation pro for maintenance recommendations so you can get the maximum benefit from your unit.
Heat pumps are most effective in regions where winter lows remain above approximately 40°F. Efficiency starts to drop below that point and falls off sharply near 25°F. If you live in a colder area, look for a model with a high Heating Seasonal Performance Factor (HSPF) and plan on supplemental heat during deep freezes to keep energy use in check.
The biggest drawbacks are the upfront cost and poor cold-weather performance. Installation can require electrical upgrades or duct changes, and once temperatures fall well below freezing, the unit may need help from a furnace or electric resistance coils. Factor in those add‑ons, along with routine maintenance, when you weigh the long‑term savings against the initial investment.
