The technician (Cody) was professional, wore foot covers and a face mask without being asked and got right to work. We just needed a capacitor, which he had in his van. A few minutes later and we were up and running. He also made some recommendations about our filters and helped get it setup correctly. Company was responsive, quick, knowledgeable and affordable. There was no upsell or "maintenance plan" sales pitch. Would absolutely use again, if we have a need!

The lady on the phone was very nice and scheduled a tech to come out the very next day in the morning. My time window was 8am-12am. I received a text and an email confirming my appointment. On the email link, you can also see the name and picture of the tech that will be coming out. The next day I received an alert at about 10am notifying me that the tech was on the way. The status email showed me his GPS location! I thought this was a really nice feature, it gave me an idea of about how far he was away. Justin was my HVAC tech. He wore a mask and shoe covers when he entered the house. I explained the issue I was having, and he first took a look indoors. He quickly found the problem was a leak in the evaporator coil. Justin presented me with all my options and facts and let me make my own decision. At no point was he pushy or trying to sell me extra services. I had some other HVAC questions, and he welcomed those and answered them and provided good suggestions. Since one of the options was a full replacement of my unit, on the same day I received a call from the Dole sales rep. He said he was able to come out that same day to give me some options of replacing the AC unit. He was courteous, came out, took a look, and we spoke through options. I was provided quotes on the same day within about 15 mins. I was very impressed with Dole and will definitely be using them again for any HVAC related jobs!

Seriously, I thought the install was well done, 2 man crew, and maybe 8 hours, a very well organized job. Seriously, you need AC or heat work, call them, you won't regret it.

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.

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.

The installer called me to tell me they were running a bit late, but they actually showed up 10 minutes early to the appointment. It took 2 days, but I now have a new working system in my house.
