Reversing Valves, Low Charge & Sensor Faults
Heat pumps can show a few telltale signs before they quit. Here’s what we see most often in Monroe and Greene counties:
- Reversing valve faults: Stuck between modes or won’t switch from heat to cool.
- Low refrigerant charge: Ice on the coil, weak airflow, higher electric bills.
- Sensor or thermostat errors: Short-cycling, missed setpoints, or erratic temperatures.
- Defrost problems: Outdoor unit ices over and never clears, especially on damp mornings.
- Blower or fan trouble: Rattles, grinding, or airflow that fades after startup.
- Drain and condensate issues: Water near the air handler, float switches tripping.

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!

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.

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!

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.

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!

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.

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.

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.

Quick Guidance for Local Homeowners & Renters
Turn the system off and call if you smell electrical burning, see smoke, notice water leaking into living areas, or the outdoor unit is entombed in ice. If performance is weak but safe, try these steps while you wait: set the thermostat to “Auto,” replace a clogged filter, and clear snow, leaves, or grass clippings around the outdoor unit for at least two feet of space.
Our Repair Process: From First Look to Steady Comfort
- Safety and system check: We verify power, clearances, and thermostat operation.
- Targeted diagnostics: Electrical tests, pressure readings, sensor checks, and defrost verification.
- Straight talk and options: We show findings, available parts, and the total price before work.
- Same-day repairs when possible: Trucks carry common components for many Bloomington homes.
- Final run test: We confirm temperatures, airflow, and mode changes, then review care tips.
Mini-Split Fixes & Dual-Fuel Advice
If you’re running a ductless mini-split that struggles in a bonus room or finished basement, we can repair it and advise on settings for better comfort. Many households near Ellettsville and West 3rd Street use a dual-fuel setup - heat pump most of the year and furnace during deeper cold. If replacement is smarter than another major fix, ask about heat pump installation to compare costs, efficiency, and noise levels for your home.

Heat Pump Repair: Common Questions
What counts as an emergency for heat pumps?
Electrical burning smells, smoke, water leaking into living spaces, or a unit fully encased in ice are urgent. Turn it off and call.
Should I use auxiliary heat while I wait?
Yes, if your system supports it. Aux heat helps maintain temperature during repairs or in very cold weather.
How long do most fixes take?
Many repairs are completed in one visit, typically 60–120 minutes depending on diagnostics and parts availability.
How often should I schedule maintenance after a repair?
Once comfort is restored, plan seasonal maintenance to improve efficiency and reduce future breakdowns.
What do ductless error codes usually mean?
Codes point to specific sensors or communication faults. Share the code when you call and we’ll bring the right parts and tools.
