Product or service reviewed: Bryant Evolution furnace and a/c

Greg and his crew are very professional and knowledgeable. They ran into problems from the previous system that required more work on there part and did not charge any extra labor, it was the same as the estimate. I really like the work they did and am anxious to see how much improvement I see in comfort and in savings on my utility bill. The heating and cooling systems at work need updated and Bates mechanical will be the people who do it!!



Product or service reviewed: Geothermal furnace and system

Words can't express our appreciation for what Bates Mechanical did in analyzing and replacing our failed geothermal system. Fast, extremely knowledgable, exceeded our expectations, above and beyond in service, on time, good communication, and the furnace works great!! We couldn't be happier with Greg and his team. Thank you.

Product or service reviewed: Repair furnace and new thermostat

I've been a loyal customer of Bates Mechanical for 10 years. They installed a furnace for me 10 years ago and whenever I need a checkup or have an issue, Bates is the company I call. They are prompt, friendly, and honest. I recently needed a pressure switch replaced and the tech (Greg) discovered that the drain trap needed cleaned. Thank goodness he caught that! I had a new thermostat installed while he was here. I trust Bates Mechanical for all my heating a cooling needs! Jill


Mr. Bates:

Thanks much for your part in making a way for a furnace to be installed. Your knowledgeable employees are the best, this winter I will have various challenges, but the house will be warm.


Dear Mr. Bates:

I Would like to thank you, your family and your associates for the work you did installing a geothermal heat pump in our house.
The house is a vintage 1960 tri-level, built with electric resistance baseboard heaters and without air conditioning, it had no duct work. Before settling on a contractor for a new system, I talked with six different companies, five from the Bloomington area and one from Indianapolis. Three of these companies declined to bid on the job. Two of those remaining felt that it was not possible to install adequate ductwork to the upper level and instead proposed systems using a second air handler in a closet on the floor. One of these two proposed a system using two conventional heat pumps. The other proposed a split geothermal system, but their bid was almost twice my budget. Only Bates Mechanical proposed a system that met both my requirements and my budget.

The system installation was timely and professional. Options on the routing of ducts and the placement of registers and returns were discussed with me at every stage of the process. All workers on the job were good natured and polite. The work was efficiently done and the work areas were cleaned at the end of each day’s shift. The three day process caused as little disruption to our house as I could have wanted.

Again I wish to thanks Bates Mechanical for the excellent work they did on a difficult job. If in the future someone should ask for my recommendation of a heating and cooling contractor. I will not hesitate to advice to contact Bates Mechanical.


They come out twice a year to check my filters, Freon levels, and other maintenance. The guy that comes out is great! He offered advice on other projects I need to tackle as well. They respond very quickly in an emergency. I’ve had nothing but good luck with them!


I have used this company over the years to install two furnaces and repair a mistake made by another company. They also do routine maintenance on my heating and air conditioning units.

I have been using this company for about eighteen years. They are terrific! My furnace stopped working during some very cold weather a few years ago. The technician that came to fix the furnace spent all day cleaning it. He did the best he could to make it work properly, it went out again two days later and they came back again. I couldn’t believe the price they charged me. It was such a small amount for the work they did getting my furnace working again. I used them to purchase and install my new furnace two years later. I have them come out twice a year to perform routine maintenance on the unit. If you sign the three year contact they lock your price in for three years on regular services so that it doesn’t go up. If there is a part that needs to be replaced then they will charge for the part only. They call me to remind me it is time for service. I feel blessed with this company.


Installed new high efficiency Bryant Heat Pump meeting energy star/federal tax credit standards installed new Bryant high efficiency furnace meeting energy star/federal tax credits standards, installed new programmable thermostat which controls heat pump, furnace and humidifier installed new Bryant humidifier.

Installation went smoothly. Supervisor was knowledgeable and explained equipment functioning. Clean up as good. Each employee of installation team thanked us for our business. This is family owned business for three generations and appears to have high ethical standards. Secretary prepared documents for us to apply for tax credits, utility company and Indiana state rebates.
