Harker Heating & Cooling

Would not recommend. I called them out to take a look at my furnace that stopped working. They fixed it, replaced a gas valve that went bad. But instead of charging me for the labor to replace the valve, they charged me half of the cost of the part which was almost $1100. I had to argue with the service department for 20 minutes just to get them to knock $100 off, but I still was grossly overcharged for the service performed. I will not be using them again.

They've always done a great job and very dependable

When the unit stopped working, I call several Madison area companies to get estimates. Harker was one of just 2 that responded quickly to schedule a visit and give me quotes. Harker was competitive, and it was replaced the next week in a day. The technician, Eric, was excellent and thorough. Unit functioning great.

Harker Heating And Cooling is the best HVAC contractor we have ever worked with in 40 years. Their web site proudly says they are an “honest company with Midwestern values.” That is absolutely true. Their representative provided in-depth advice, answered our questions. and returned our messages. Their techs were knowledgeable, professional, careful, and friendly. They were on time, on call, and on budget. The service they provided for us over the years could not be better. So when the time finally came to replace our old furnace and A/C we selected them. Unfortunately, they encountered many unexpected problems installing our new equipment. Many more than they had anticipated for the job. But their representative pledged to address every one of them no matter how hard it was for them or how much of their time it took. And that is exactly what they did. No quibbling and no questions. They got the job done right. If you want an honest family contractor who stands behind what they do, and lives by those Midwestern values, then this is the company to hire. You will be glad you did.

Excellent company. On time, on budget, good materials, good workmanship, friendly, courteous, professional and easy to work with. Especially good at setting up the job specs ahead of time by email. And good attention to Covid-19 precautions to keep homeowner and technician safe. Would definitely hire again.

Furnace was repaired and is working now.

We had an appraiser tell us we needed someone to look at our tenants AC because they found water, it's a simple thing we probably could have done it but we needed to close the next day and get a professional to look at it, it's busy season so they charged $300 to come out the same day (they arrived earlier than they told us and so they had to wait for us but they stayed). It only involved flipping a switch and some advice mainly but it really helped us with our closing and I felt that they were honest. They are probably more expensive but they are open 24 hours.

Excellent work. Furnace and AC were installed quickly. Bill and Ryan (I think that was there names) were very professional and personable. They did a great job.

It all started when we needed to get our humidifier on our HVAC looked at because it didn't work, and was installed by another company. They were nice and prompt and came out and fixed it. My husband was in and out of the basement while they were doing it. After they left, the heat never turned back on. It was a warm day but that night was cold, so when the heat should have kicked on, it didn't. So we called, they came out (on a weekend and charged weekend prices to look at it), said they needed to order a part and would be back on Monday or Tuesday. On Monday they called and said they would come Friday at 7:30 am. They showed up an hour late. Replaced the part. Got it working. They are insisting that the fact that the system never worked again after they worked on it is a total coincidence and are charging us hundreds of dollars. They are also saying that my husband was never in the basement while they were there (as he stated that he saw them working with the wires and they claim it isn't possible because they claim he wasn't in the basement). We cannot believe that it is possible that they came and serviced our system and then that just happened to be the exact time that the system broke on its own. TL;DR: Pros: Came quickly for initial call Cons: Likely broke our system and then charged us hundreds of dollars to fix it. Showed up an hour late with no communication, thus costing us more money as we weren't at work.

Options were provided via written quote. Model selected was fair price and installation was done in 1/2 day. We also have had new furnace installed a few years ago by Harker. Professional service.

The ac coil ( defective part) was still under warranty, but the labor to replace it was not. The service man was here for 4 l/2 hours (he could have used another technician to help him). The first problem was that he was giving the wrong part for my ac unit, so he had to take the part back to Harker and retrieve the correct part (took about 40 minutes). It was a cool day, so it was difficult to properly test the unit after the installation. The technician said it would be necessary to return on a warm day to properly test it. To date, that has not happened, and we have had temperatures in the 90's for a week now. When finally finished, the bill was $657. And this is after an initial "spring tune up" (two weeks prior) that cost $262. Outrageous! I didn't get a paper copy as the technician figured the bill on his computer. I wrote the company and asked for a paper copy, and got one, but again, nothing was detailed, and it just said the bill was $657.

Technician arrived promptly, completed installation in less time than expected, charged less than initial estimate. Good communication, organized, professional.

$108 to come out and diagnose the problem whIch was just a crack drain pipe receiver:) so they come out to repair it for an additional $249.83. I’m a bit confused by the price and ask how much was the part? They won’t give me that amount, they tell me it’s charged per job. Call to find out how much the part actually cost from Lenix, cost $67. They were at our house less than 20 minutes I was charged $180 for for 20 min. of service:( Won’t use them again:( I was also promised a phone call back to discuss a possible credit and did not receive one...no surprise:(

Very professional, informative, and responsive. Harker provided options and described the differences. They were punctual and completed the entire job in 1 day. Their pricing was competitive. They provided energy rebate forms and information.

When we need to get a new furnace filter, we know that they have the furnace filters we need. We have a Trane, and they are a dealer for Trane furnaces. We will actually have them come and check out the furnace for winter.

EXCELLANT and I did not have to pay in advance.

They were excellent workers. They always worked well. I've used them a lot. They always send out one worker.

All went well and the installer was friendly, knowledgable and efficient. Per visit and hourly costs are a bit steep.

Installation team was prompt and professional. We had an issue a few months later and they eventually took care of them.

It takes maybe an hour to do the work. There is usually one worker who comes. They leave the area very good. They're very efficient.

They provide a friendly service, I had a good experience with sales and service, and they are very efficient and clean.

Everything went smoothly. The technician was on time and performed the tune up efficiently.

Diagnosed problem, ordered part and came back to finish repair- under warranty.

Installer arrived on time, disposed of packaging material and showed me how to use the product.

They did an excellent job. They came out and took care of the problem. I was very happy with it.
