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"

"Our relationship with All Star Mechanical began with Chris coming out to diagnose my AC problem. He tested the system and diagnosed it as low on refrigerant likely due to a leak. We asked to get a quote on replacing the AC and the entire HVAC system. The furnace was a 25 year old Trane. The air filter was 1in thick and struggled to blow through a non-MERV filter, and I wanted cleaner air for the health of my family, especially since wildfires aren't going away anytime soon. We also wanted a whole house humidifier to assist the Vornado units we run 24/7 in the winter. Larry presented us with a variety of options for upgrading my HVAC system, not trying to sell me a system too large and expensive for our needs or climate, then explaining how everything works and how it works together to make our home efficient, safe, clean, and comfortable. The installation team was fantastic. They were scheduled for a 2 day installation and over performed installing the entire system in one day. Matthew and the 2 Nicks were great! Within 2 hours of installing the General Aire MAC high efficiency air cleaner we noticed the air felt and smelled cleaner, in spite of the poor air advisory warning for that day. Finally, Chris buttoned the system up completely by running updated thermostat wiring and relocated my thermostat so the new system is compatible with my ADT Z-Wave ADC -T2000 monitored thermostat (my request)! Throughout the entire job, Larry stayed in touch, either by email, phone, or text to make sure everything met or exceeded our expectations. They are definitely All Stars!"

"Beware of shipping issues with this company. Ordered an ice maker installation kit on 10/10/25. Shipping was due no later than 10/20 according to company and FedEx tracking. FedEx tracking showed the package at their facility for 8 days without moving beginning on 10/15. Called FedEx 3 times. Each time they said they cannot find package and I have to contact shipper. Shipper has to make a claim, they will not mark it as lost. Called Appliance Parts Pros twice. Each time they say FedEx has to mark package lost before they will do anything. They also state they have to wait 14 days from them before doing anything because of their contract with FedEx. I don't care about their contract, I want what was ordered and paid for. Just going in circles with them and FedEX. If they shipped after 14 days it would be 22 days from that point, 32 days from the date of order if they shipped it that day.

Heating and Air Conditioning questions, answered by experts

A damper motor can last up to 15 years, but it can wear out more quickly than that if you run your HVAC unit a lot. So you might expect a longer life in a colder climate than if you live in a warmer climate.

Mold in your air conditioner isn't a good thing, as it can be harmful to your health. If the mold travels through the ductwork or is blown out of the A/C, you and your family can inhale mold spores and develop respiratory illnesses and other problems. Preventing mold from growing in the air conditioner will help protect your health.

A home AC unit provides anywhere from one-half to five tons of cooling and requires approximately two to four pounds of refrigerant per ton of cooling. At approximately five to 10 minutes to fill one pound of refrigerant, a home that requires three tons of cooling will take about six to 12 pounds of refrigerant and approximately 30 minutes to two hours to completely recharge the unit.

Window AC units use a fair amount of electricity during use, but the usage pales in comparison to central units. As a matter of fact, window units use around a third of the amount of energy as a central AC. On average, a window air conditioner costs between $15 and $40 per month to run, though this depends on a number of external factors.

Is mold in an air conditioner dangerous? Running an air conditioner with mold isn’t safe because it can spread harmful mold spores throughout your home. These spores may cause respiratory problems, allergies, or aggravate asthma in household members and guests. If you suspect there is mold hiding in your air conditioner, it’s best to stop using the HVAC system until the mold is cleaned to avoid health risks and further contamination.
