Harster Heating & Air Conditioning

I dont write many reviews and certainly not for ordinary experiences. Harster has taken care of me twice now by going above any beyond what is expected. Great customer service and very professional employees make this operation first class. Have already recommended to several others.

Normally don’t like to leave bad reviews, since it’s someone’s livelihood. But this one is just so bad that I can’t find any excuses for them.
Not sure what the issue is with Carla (or Karla), who answered the phone at Harster. I asked for same day service, and she tells me we’re out of her service area, when Downtown St. Louis is clearly included on their website. Then I called back stating that we can wait for them since they have such a great reputation for service and expertise, she said it’ll be the following week the earliest, I said ok, let’s schedule it. Then she changed her story saying «sorry, we can’t, how about calling Hoffman’s or other companies? We just don’t have enough manpower.»
What? Ok, if you’re trying to keep new customers away, you succeeded. Congrats.

I’ve worked with several other heating and cooling companies and Harster has always treated me well and had the work done quickly. I would highly recommend them to anyone in the area.

I called Harster this morning, before their posted hours. I assumed I was going to get a machine and leave a message, but a very courteous woman answered and helped me get an appointment for the same day. It was a hot, HOT day and my air conditioner was blowing air that was NOT the cool air you want on a day like this. She said they’d call before noon when they were on their way. Only a half an hour later, a technician, Jerry, was out at the house. He was very helpful and knowledgeable, and explained to me what was going on, plus asked questions to help him diagnose the issue. My husband and I have been discussing replacing the whole HVAC unit, and if we do, Harster will be at the top of our list to get a quote from.

No one is ever happy that their 20+ year old central air unit dies. What I loved is they quoted me price to repair, that would have brought maybe two years more. But I asked for sales guy to come out, and less than 20 hours later I have a much more energy efficient central air unit, at a price that was hundreds less than for equivalent and better units than Anton’s quote.
The expertise shined through from each and every employee/​professional I dealt with… from the initial service tech who diagnosed problem, to the outstanding sales professional, to the friendly and thorough service people who installed new unit, to friendly and helpful finance people. The whole process was pleasant. The best part is they got it done in one day, even in the rain, and I was able to have my wife come home to comfort from her trip out of town!
Great job, everyone!
Needless to say Harster gets my strongest recommendation!

Unethical, unprofessional, charges were astronomical!!! Had a gas leak that was not fixed and the charge was $ 591!!! I am single and work 55 hours a week and could not be at my home to supervise their work. They claimed that every part of the gas line needed to be adjusted when the leak was actually coming from the inside of the gas range, as discovered within 20 minutes by Laclede Gas. I never once was warned about the charge and they required a credit card to come to the home. Then they had the audacity to charge my card and not even communicate anything about the work. I found out the issue wasn’t resolved by a Laclede Gas inspection and then was sent a receipt in the mail for $ 591!!! I will report them to the BBB. Do NOT use them!

I highly recommend Harster for any furnace needs. Dan, my tech, was great. On time and solved the problem quickly. Very knowledgeable and didn’t try to sell me a bill of goods. I was so impressed that I signed up for a service agreement so they can do an AC start-​up check in the spring and another furnace check next fall. These guys are great.

I got back from NYC today turned on my thermostat only to have cold air blowing on my face (it was 41 degrees outside today). I did my own troubleshooting, but it was clear that the heating element on my furnace was out as the power, gas, and fan were all working. I called Harster after seeing the reviews on Unilocal at 10:00 AM, and a courteous serviceman was at my door at 11:00 AM. He showed me around my furnace, what went where, gave me tips on my filters (and how to save money on them), and had a new element in and running 25 minutes later. The price was reasonable, the service was polite and informative, and the promptness was unrivaled. I can’t recommend this company enough and I only hope that the quality of service remains the same as they will undoubtedly become more popular with the quality of service they provide.

I called this morning because my A/​C was on the fritz and they came out within 2 hours of my phone call! The repair man was very friendly and knowledgeable and he was able to fix my Air conditioner in a snap. I definitely recommend Harster! Check out their coupons on their website by signing up for their email; i saved $ 20.

Amazing service and Savings. They were almost $ 200 cheaper than climate masters. Rick was a great serviceman! He even waived the service fee and just charged for parts and labor… they now a have loyal customer in me!

While visiting St. Louis, my family’s AC broke down at 3pm on a Sunday of a holiday weekend. After reading the other reviews, we called Harster. Wow. They arrived in less than 90 minutes, diagnosed the problem immediately and had it fixed in a jiffy. To top it off, Jerry, the technician, stayed for a while just to be sure it was all working correctly before he left the area.
This is the finest example of customer service I have ever encountered. I highly recommend them to everyone.

Harster Heating and Cooling just left my house and I could not wait a second to write a review.
This company has superior service and timeliness. My furnace stopped working and I called Harster after reading the other reviews on Unilocal.The receptionist was very nice and she had a technician out in less than 2 hours. I ended up needing a new system, but two of the nicest and most informative technicians came out the very next day and completed the work. They talked to me about the system and what I can do to maintain it. The price was fair and what they quoted originally did not change after the work had been done.
I would recommend this company to anyone.

Called for furnace service. Call taker was very nice and a serviceman came within two hours. Very polite and professional business. Hopefully won’t have to call again, but if I do, they have my business.

Harster was great from beginning to end. The lady who answered the phone was very nice, and scheduling the appointment was pretty easy. The tech arrived exactly on time, was professional, talked me through what he was doing (I was interested since HVAC systems are a mystery to me), and was done on time. Prices are reasonable and service is great. 5 stars.

My furnace wasn’t keeping up like it should and, after a poor experience with another local HVAC company, I was looking for someone new. Harster just did everything right. Prompt communication, on time for the appointment (to the minute!), knowledgeable and courteous tech, explanations of everything that was done and best practices for the future… It’s just the way these kinds of things should be done, and so often aren’t. Thanks Harster — I hope I don’t need your services again, but if I do you’ll be my first call.

I was a new customer and called these guys on the coldest day of the year. They came to my house within two hours and had my furnace repaired within an hour. I’ve several older furnaces and a/​c units that need to be upgraded, and I will definitely call Harster. They are the best.
