I was really pleased by the process for getting our AC replaced. Matt worked with me on a bid for…read morethe new unit in October, and spoke intelligently about the options, where other companies did not seem as educated on the components. This bid was actually less than the competitors, and they had not been around as long as Harster! It was an easy choice. We scheduled to do the replacement in January. Jim and his team came out to do the install and addressed some additional needs to increase the air flow, make the existing unit up to proper code, and make the filter track so it fit filters appropriately. The last unit installation I'm sure was a DIY job or done by a less qualified company. Jim addressed all those issues. I was on a meeting when he was all finished and didn't get to go see the finished product until after he left. It was beautifully done and very neat.

Harster Heating and Cooling just left my house and I could not wait a second to write a review…read more This company has superior service and timeliness. My furnace stopped working and I called Harster after reading the other reviews on Yelp. 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.

However, recently they did a bid for an AC system, and we ultimately chose another company whose bid was lower for a better system. I called today for another AC unit that was out, and their office person told me bc we chose another company for that work, they put other, better customers ahead of us and could not service us for the time being-- as if we're being punished for not giving them the business. She said we did not call to follow up on their bid. It's THEIR responsibility to follow up on bids. We've paid them many thousands of dollars over the years. Super unprofessional IMO.

I was quite impressed with availability of the appointment and the flexibility in choosing a time that worked for my schedule. Malcom let me know first by text that he was on his way, then called to speak with me to confirm he would be arriving in 30 minutes. From the moment he arrived, I felt I could trust his expertise as it was clear he knew what he was doing. He diagnosed the issue in just minutes and made some recommendations to mitigate the issue. He offered some ideas of what I could do myself and what he recommended for professional servicing. I appreciated that he was looking out for my wallet. I was happy to let him do recommended work. Fast, courteous and professional service that didn't break the bank. Very reasonably priced. Highly recommend. Malcom deserves a raise so I hope his boss reads this!

They followed up with paperwork that provided three options and the available discounts. I'm a former Information Technology engineer, so I appreciated their cleanliness, routing of wires and piping, and relocating duct work to provide easy access to the system and the filter. I went with the Trane system. The Trane system has a user-friendly smart thermostat. That is exactly what I was looking for. It was nice to see my electrical bill a lot lower. It's very efficient. Marshall Y. and Steve A. kept me updated throughout the process and provided easy-to-follow system programming procedures. Great job, Guys! Nice clean work. I will be sure to recommend your company.

Spire stopped by to check on a possible gas leak and discovered our water heater wasn't venting…read morecombustion gases properly into the flue pipe shared with our HVAC. We called Hoffman Bro's first because they deal with both, and they charged us ~$300 to tell us the same thing as Spire and suggest we call a chimney sweep to check the flue pipe for blockages. We couldn't find a chimney sweep that either could be booked within the month to inspect and give us an estimate, and if they could be booked in that time frame they didn't understand the problem we described and wanted us to fork over hundreds to inspect and sweep our flue. Luckily, an acquantance gave us Crestside Ballwin's number. The receptionist called Dave over to learn about the problem and within a minute he figured that the roofers we had over a few weeks ago probably botched the install of the new flue pipe cap. They had a tech come over two hours after I called and sure enough that was the problem. Anyhow, these guys were solid for us, I'm super thankful we found them.
