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).

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"

All Star Mechanical, is a locally owned and operated, HVAC business. We have many years of experience behind us, thus we are confident that we can provide you with the best in HVAC service. We always respond quickly to your requests, always price reasonably, and the work performed is of the highest caliber. We use the best in materials as well. Thank you for selecting us and we welcome your questions.
"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 do 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, inspite of the poor air advisory warning for that day. Finally Chris buttoned the system up completly 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 Allstars!"

My main goal for every job is to do excellent work, with efficiency, at an affordable rate.

I understand every person and need is very different, so I will listen to what you need, carefully, and work with you to find a solution.

FAQs for heating and air conditioning service projects in Dewitt, MI
Knowing how long your existing HVAC units can last is essential to determine if you need a repair or replacement. Typically, most modern air conditioning units can last between 15 to 20 years, and most furnaces can work properly for 15 to 30 years. If your HVAC system is on the older side and you decide to replace one unit, it might make sense to replace both simultaneously to save on costs and future hassle.
While different HVAC contractors might offer higher or lower prices than competitors, the best time to replace your HVAC system is when customer demand is low. The beginning of summer and the beginning of winter bring the most demand for HVAC systems, so if you can, consider replacing your HVAC units in the early spring or fall. Many HVAC companies offer special off-season coupons that help lower the overall cost.
The average cost to hire an HVAC contractor is between $50 and $150 per hour if charging hourly. However, some HVAC contractors will charge a flat fee by the type of service they are performing—for example, an inspection can cost between $150 to $500. Keep in mind that emergency repairs—which are made after business hours or around major holidays—generally cost more than scheduled repairs.
Yes, most states require HVAC technicians to be certified, and for good reason. Hiring an unlicensed HVAC technician could lead to poor quality work, costly future expenses, and potential code violations.
As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include:
The owner, principal, or relevant manager passed a criminal background check
Required to have applicable state and local licenses
Maintain an average star rating of 3.0 or better on our network, if they have at least one review
Paying to advertise their services
Meeting any other eligibility criteria required by Angi
Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.
The average cost of HVAC repairs is around $350. However, that price can be as low as $100 or as high as $2,000 or more, depending on the repair. For example, replacing a capacitor is a relatively inexpensive repair, ranging from $100 to $500. However, a compressor repair is a more expensive repair, ranging from $750 to $2,000.
