Quiet, efficient comfort for Bloomington homes

Heat Pump Installation in Bloomington, IN and South-Central Indiana

When summer humidity settles over Kirkwood Avenue and winter air rolls across the SR-45/46 Bypass, a properly sized heat pump keeps your home comfortable year-round on a single system. Bates Mechanical provides heat pump installation across Bloomington, Spencer, Linton, Ellettsville, and surrounding Monroe, Owen, and Greene County communities — with clear options, careful sizing, and clean workmanship on every job. Indiana Energy Saver rebates of up to $8,000 are currently available for qualifying households, and we'll walk you through eligibility before you commit to anything.

Heat Pump, Hybrid Heat, or Furnace Replacement — Honest Comparison Before You Decide

Heat pumps move heat rather than create it, which makes them efficient year-round. They work best in well-insulated homes and pair well with a gas furnace in a hybrid configuration for the coldest days. If your bills are high, rooms run warm in summer and cool in winter, or you want quieter operation, a heat pump is worth a close look.


But it isn't always the right answer for every home. Older homes with significant air leakage, homes on propane with favorable fuel costs, or homes where ductwork would need major work may be better candidates for a straight furnace replacement or a hybrid system.


We'll compare expected energy use, comfort benefits, and upfront costs at your estimate so the decision is based on your home's actual numbers, not a general pitch.

I appreciate the great work that they did and would recommend them to anyone in need of furnace repair services. Thank you!

Lauren W.

Overall, I'm very happy with the experience I had with Bates Mechanical and would recommend their services to anyone in need of AC repair. Thanks for a great job!

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.

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

Brian M.

These guys are the best!! Came out the same day to replace a faulty thermostat and did a fantastic job. Matt solved a previously bad install and fixed it quickly and correctly. Would absolutely recommend Bates to anyone looking for great, friendly, and cost effective HVAC service.

Kelly S.

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

AJ M.

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.

Austin C.

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 G.

What I thought might have been was not at all what it was thank God it was only a Capacitor thanks for your help

Wendy S.

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!!

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.

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.

Brenda

Prompt and courteous

Alisha C.

Clean, professional and friendly! We received a full HVAC replacement and duct installment for a home addition. They arrived on time, protected our floors, were very respectful of our home and showed us how everything worked when they were finished. I would highly recommend Bates Mechanical to anyone looking for HVAC services.

Jamie P.

Very knowledgeable technicians

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.

Don C.

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

Cheryl G.

When our old furnace recently bit the dust, we called Bates. Someone was there that day. Our system was so old they were not able to obtain the needed piece so we opted for a new system. The crew arrived as scheduled, got straight to work, had the old unit removed immediately and the new one installed and running within hours. Everyone was pleasant and professional.

Candace C.

Highly recommend! Friendly, on time, great communication, and excellent service! Thank you, Matt!

Adam L.

Our air conditioning went out in the morning around 1130, my wife called bates and they said it could be a couple hours before they could get to us. The guy that showed up had been working all day and was ready to go home but he came to our house around 5, he found the problem why it wasn’t working in 5 minutes, changed out our capacitor and he could’ve high tailed it out of there but he stayed and hooked up his hose to clean off the outside ac unit. Super nice guy, his name was Matt, me and my wife highly recommend using bates heating and cooling out of freedom Indiana. Thank you guys so much!!!

Susan J.

Thank you to Tom with Bates Mechanic Heating & Cooling for getting our A/C unit up & running again as quickly as they did. Thanks to Patty for getting it arranged so quickly! You can count on Bates for great service!

Ducted and Ductless Heat Pump Installation Across South-Central Indiana

Ducted heat pumps deliver whole-home comfort using your existing duct system — the most common installation type for homes in Bloomington, Spencer, and Linton. Ductless mini-splits are the right choice for finished basements, sunrooms, additions, garages, and any space without reliable duct access. They're particularly common in older Bloomington homes near the Near West Side and in additions out toward Ellettsville and Owen County. If you have uneven temperatures or spaces without ducts, a ductless setup solves the problem without major renovation.

Indiana Heat Pump Rebates — What's Available and How It Works

Indiana is one of a small number of states with an active rebate program, and the savings are significant for households that qualify. Here's what's currently available:


  • Indiana Energy Saver HEAR program: Up to $8,000 toward a heat pump HVAC system for households below 150% of the Area Median Income. Rebate applied as a point-of-sale discount — no reimbursement paperwork, no waiting.
  • Indiana Energy Saver HOMES program: For households above 150% AMI, rebates are available on whole-home retrofits that achieve a minimum of 20% predicted energy savings. Qualifying upgrades include Energy Star-certified HVAC systems.
  • Bloomington Green Home Improvement Program (BGHIP): Bloomington residents can stack this city rebate on top of the Indiana Energy Saver rebate, as long as the combined total does not exceed the project cost.
  • Utility rebates: Duke Energy customers in the service area may qualify for additional rebates on qualifying heat pump equipment. We'll check current amounts during your estimate.


Federal heat pump tax credits under Section 25C expired December 31, 2025 and are not available for 2026 installs. The Indiana Energy Saver program remains active and funded, but rebates are awarded on a first-come, first-served basis — there is no guarantee of availability at any given time.


We check current program status before every estimate and include applicable rebates in the project proposal so you see the real out-of-pocket number before deciding.

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.

Heat Pump Installation Across Bloomington, Spencer, Linton & Beyond

Our routes cover neighborhoods around the IU campus, West 3rd Street, and the Bypass, with regular availability in Ellettsville, Linton, and Spencer. We also serve homes toward Martinsville and Bedford and west to Jasonville and Clay City. Share your address 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 much does heat pump installation cost in Indiana?

    Installed cost varies based on system type, home size, and whether ductwork modifications are needed. The most accurate number comes from an in-home estimate. For qualifying households, Indiana Energy Saver rebates of up to $8,000 reduce the out-of-pocket cost significantly, and financing is available to spread the remainder over time.

  • Can I get a rebate for installing a heat pump in Indiana in 2026?

    Yes, if you qualify. The Indiana Energy Saver HEAR program offers up to $8,000 for heat pump HVAC systems for households below 150% of the Area Median Income. Bloomington residents may also qualify for an additional city rebate through the BGHIP. We verify your eligibility before the estimate.

  • How do heat pumps perform in Indiana winters?

    Modern cold-climate heat pumps operate effectively well below 0°F. On the coldest mornings, auxiliary or furnace backup maintains your set temperature. Proper sizing for your specific home is what determines real-world performance — that's why an in-home load calculation matters.

  • Should I choose ducted or ductless?

    Ducted is the right choice for whole-home comfort when existing ductwork is in good condition. Ductless is better suited for additions, basements, and rooms without reliable airflow. We'll make a specific recommendation at your estimate based on your home's layout and condition.

  • Are rebates available for heat pump installation in Owen County or Greene County?

    Indiana Energy Saver rebates are available statewide for qualifying households, including Monroe, Owen, and Greene counties. Bloomington city rebates through BGHIP apply only to Bloomington residents. We'll confirm what applies to your address before your estimate.
