Quiet, efficient comfort for Bloomington homes

Heat Pump Installation & Ductless Mini-Splits

Heat Pump Installation for Year-Round Comfort

When summer humidity lingers over Kirkwood Avenue and winter air rolls across the SR-45/46 Bypass, a modern heat pump can keep your home comfortable without the constant ups and downs. Bates Mechanical provides heat pump installation in Bloomington, IN with clear options, careful sizing, and clean workmanship. Whether you’re near the IU campus, in Elm Heights, or out toward Ellettsville, Linton, or farther out, we’ll help you compare systems and choose the one that fits your house and budget. If your current unit is acting up, we can handle your heat pump repair and map out a smooth path to replacement when the timing is right.

Is A Heat Pump Right For My Home?

Heat pumps move heat rather than create it, which makes them efficient year-round. They shine in well-insulated homes and balanced floor plans, and they pair well with a gas furnace in colder snaps. If your bills are high, rooms run warm in summer and cool in winter, or you want quieter operation than an older system can provide, a heat pump is worth a close look. Bates Mechanical will compare expected energy use, comfort benefits, and upfront costs so the decision is straightforward.

Matt from Bates Mechanical was able to solve our issue quickly and took the time to explain how we can avoid it in the future. I would really recommend them to anyone else with a heating issue in the cold weather!

Jude S.

Just love this business. They have always taken care of me. I trust them not to rip me off. Their work has always been reasonably priced and reliable.

My AC went out and I wanted to get it replaced quickly. I called a franchise company and they got out here the next day, tried to sell me outrageously priced units, and guaranteed next day install. I called Bates Mechanical next and they came out that same day and quoted me half the cost of the other guys. Matt even tried to do what he could to get my AC going until they could get back for the install. I couldn’t be happier with the professionalism by all, honesty in all aspects, and making sure I fully understood what had happened with my old unit and how to use of my new one. Bates Mechanical has a customer for life.

Brian M.

Erica M.

Had a different company come out in the spring, put too small of compacter in. Called them back today and they said they would make time to come out later today but might not be able to fix it. Called this company and said they would be out within a couple hours, arrived promptly which wasn’t expected on weekend call. Took about 20 minutes for him to fix the problem and charged about half the price as the other company for an off hours call! Would highly recommend this company. 👍🏻

Heidi L.

Bates installed a new furnace for us this fall. They went above and beyond to do the job right. Knowing we sometimes have water problems in the basement, they put the unit up on blocks, which is exactly what we wanted. Thanks, Matt for coming out to do the quote and following up on the project, and thanks Tom and Larry for working hard to get the old furnace out and the new one in and running! Great company and people! - Daniel & Heidi

Bates Mechanical installed a new Bryant HVAC system in our home about 9 years ago. This winter we were having an intermittent noise issue with the inducer motor on our furnace. Because THEY registered our system when they installed it, all parts have a 10 year warranty. They came out quickly, assessed the problem, and replaced the part. Yes, we paid a little for the labor (less than an hour) but it saved us hundreds of dollars. Through the whole process they were very professional and easy to work with. We definitely would recommend their products & services!!

Kelly S.

We’ve used Bates for over ten years. Highly recommend!

Tice E.

You get what you pay for. I paid for good equipment and Bates put it in for me. Absolutely the best, most professional installers and office staff I have ever seen. They ran new ductwork where mine was inadequate or decayed and put in a filter that lasts almost a year between changes. My heating and cooling costs are down almost 50% and seeing as I'm on LP, every penny counts. You want cheap, I know I guy who knows a guy who can slap you in a furnace for a couple six packs and lunch; you want a top of the line heating system, and you want to pay for it, you call Bates and you won't regret it.

Just had Bates Mechanical install a new Bryant Evolution heat pump system. Old unit was 15 years old so decided that it was time to replace. Greg the owner came out and gave me a quote on the new system. Three days later Tom, Larry and Kain came out and installed it. Everyone was professional and good at their job. System was installed in around 4 hours and the guys left everything as clean or cleaner than they found it. Would definitely recommend these guys to anyone who is looking for a fair, competent HVAC company.

John W.

Bates has been my HVAC company for many many years great people very professional family owned and run highest quality work available

B S.

Always easy and great dealing with these guys. Everyone in the company is amazing to deal with. Patti is great, never got frustrated no matter how many times I called and Greg, Todd, and Matt are great. Very professional, friendly, and fair. If your having any kind of A/C-furnace problems I highly recommend Bates.

Lee M.

Great clean, professional installation. Product installed is very quiet and efficient. Bates is a wonderful company that I have been associated with four plus years. Highly recommended!

Kelly S.

We've used Bates for sixteen years. They've put in a new HVAC system and do semi-annual maintenance for us. Todd's awesome! Highly recommend.

William G.

Very professional from start to finish. Did a superb job in doing installation and cleaned up thoroughly when the job was over.

James N.

Bates Mechanical is the best Heating and Cooling company in southern Indiana I have ever had the pleasure of doing business with.Matt showed up when he said he would and gave me a more than fair estimate to replace my furnace and heat pump after being told some pretty ridiculous figures from other companies.They are a no gimmicks straight to the point kind of company.They didn’t try to sell me something I didn’t need and his guys showed up on time and did a wonderful job installing my new equipment. I couldn’t be happier.If you are looking for a experience like this I would 100% recommend them to anyone.

Raymond L.

Great place to work with friendly, professional , prompt for appointments for our twice a year preventive maintenance. Our service technician Todd is the best!

David H.

Professional, friendly, and fast. Can’t ask for any more. I will be recommending Bates to every one. I’m old enough to really appreciate his level of professionalism.

Cody S.

One of the top notch HVAC businesses in the area. Quote was reasonable and installation was clean and thought out. Working with a family owned business who takes pride in quality and craftsmanship is why chose Bates because I knew they would stand behind their work. They also supplied a temporary mobile system for the dry wall finishers so we’re not circulating that dust through our brand new system. Consider this when new construction, dryer vents, bath vents, and cooktop vents by them when the sheet metal guys are on site.

Arndt S.

The team was well organized, polite, careful, and efficient during the installation of our new hybrid heat pump/AC system. They even cleaned up after the work was done. I highly recommend them.

Highly recommend Bates Mechanical! Todd showed up on time, explained things well and I feel confident my HVAC is ready for the changing season. Very reasonable and came the next day after I called for an appointment.

Easy-going tech, pleasant to work with. Completed our HVAC installation to a high standard.

Cassie G.

I called to see about having an estimate & subsequently had them replace ALL the duct work under my house from water damage & also asked about having them service my furnace at the same time. They did a WONDERFUL JOB. VERY professional & definitely live by the golden rule as they claim. They even moved my thermostat for me as well & it was so much cheaper than I'd expected. I've found new AC/furnace repair techs for sure!!

Jay C.

Bates installed my complete system 22 years ago. Only have had to call them twice. First time was a year and a half ago for a new capacitor on the AC outside unit. The second time was yesterday because the heating unit had been getting louder and I thought maybe a bearing was going out. The same repair man came, easily fixed the problem and couldn't have been more professional and helpful. I called yesterday at 830 am, he was there at 1000 and he was done about 1045. You can't ask for better service than that. I highly recommend them to anyone who wants to know.

Luz W.

After my ac broke down on a hot day, I called Bates Mechanical for help. They were so understanding about the situation and advised me to do an ac replacement and not just an ac repair. They did the ac installation for my house and I am so thankful that I called them. They are very professional and skilled.

Heather G.

If you need an HVAC company, then Bates Mechanical Inc. is your go to. They are a family-owned business in my home town and have been around for my entire life. I'm sure they have been working on every house in the neighborhood for as long as I can remember. The customer service is always prompt and very professional, which is so appreciated by someone like me who counts their time in minutes, not hours.

T D.

This is a three generations family owned business. The employees are extremely kind, professional and intelligent. I have known Bill Bates for two decades, his son Greg Bates for nearly 55 years. They are available, no matter how big or small the job is. I highly recommend Bates Heating and Cooling in Freedom IN.

Actually they did a great job they do deserve 5 stars.

Whole-Home or Room-By-Room Solutions

Ducted heat pumps offer whole-home comfort using your existing ducts. Ductless mini-splits deliver targeted heating and cooling for finished basements, attic rooms, sunrooms, and garages - this can be a great fit for homes around Near West Side and additions west toward Ellettsville. If you have uneven temperatures or spaces without ducts, a ductless setup can solve hot-and-cold trouble without major renovation.

Efficiency, Costs, And Incentives

Today’s inverter-driven systems modulate output for steadier temperatures and lower electricity use. During your estimate, we’ll compare efficiency ratings, projected bills, and sound levels, then walk through warranties and maintenance. Incentives and rebates change during the year; we’ll review current programs and factor them into your total project discussion so you can see the complete picture.

From Set-Up to Quiet Comfort

Most projects finish in a day. We start with floor protection, remove old equipment for haul-away, set the outdoor unit and air handler, and connect line sets and controls. The system is pressure-tested, evacuated, and charged to spec. We confirm airflow, verify thermostat communication, and explain how defrost mode works on cold mornings. Before leaving, we review filter care and best practices for Bloomington’s shoulder seasons.

Dual-Fuel Options for Cold Snaps

Many Bloomington homes benefit from a dual-fuel setup that uses a gas furnace during the coldest hours and a heat pump the rest of the time. If your existing furnace has life left, we can integrate it for efficient, comfortable operation. If it’s near the end, learn more about heating installation and compare costs and timing to keep your home ready for the next freeze.

Local Coverage: Scheduling for Bloomington & Beyond

Our routes cover neighborhoods around the IU campus, West 3rd Street, and the Bypass, with regular availability in Ellettsville and Linton. We also serve homes toward Martinsville and Bedford and west to Jasonville and Clay City. Share your street, and Bates Mechanical will confirm our earliest estimate window.

Payment Plans That Fit

You can spread costs over time with quick decisions and clear terms. Start with a free estimate, then apply online. Many households choose financing to lock in comfort before peak summer or winter rather than waiting for the next breakdown.

Heat Pump Installation: Quick Answers

  • How do heat pumps perform in cold weather?

    Modern systems heat well during typical Bloomington winters. On the coldest mornings, auxiliary or furnace backup can maintain set temperature.

  • Should I choose ducted or ductless?

    Ducted is ideal for whole-home comfort with existing ducts. Ductless fits additions, basements, and rooms without reliable airflow.

  • What is the defrost cycle?

    In cold, humid air, outdoor coils can frost. The system briefly reverses to melt ice, then returns to heating. Indoor comfort is maintained.

  • How long do heat pumps last?

    Many systems run 12–15 years with proper care; inverter models often deliver better comfort and quieter operation throughout their life.

  • Are rebates available?

    Yes, but programs change. We’ll review current incentives during your estimate and include them in the overall proposal.
