Fast response - diagnostic appointment of AC unit scheduled for early next morning…read more Tech Kayla diagnosed problem quickly and explained options for fixing the AC unit quickly and clearly. Refrigerant was gone indicating it had one or more leaks. I decided to have the refrigerant refilled as stop-gap measure. The total cost for the appointment was $517. It was a failure on my end to not ask if I could have gone with less refrigerant to save money. In the end I'm only using the AC unit for 14 days before having it replaced. Kayla's estimate for repair was approximately $5000 plus a chance for it to be more based on the time it would take to find the leak(s). I decided to go with replacement of the AC unit based on its 11 year age and the approximate cost of $6000 to fix it. Sales person Steve contacted me later that day and scheduled an appointment to get an estimate for replacement. I found him personable and professional and he gave his estimate promptly with the information I needed about it. I had 2 followup questions that he quickly answered. In the end I went someone else for the AC unit replacement, but more because of an option to include switching my furnace to have an electrostatic filter at the same time I did the AC unit replacement. The cost of the AC units were similar. Overall very good diagnostic and fix, as well as quick followup on providing an estimate for replacement.

Thielmann: I'll try to give a brief background. The furnace (unit also has AC component) in my…read morecondo was having white smoke/steam come out of the external vent during some of the extremely cold weather we were having. Even though my furnace was not making any unusual noises, smells, or setting off my carbon monoxide detector, I was still concerned as no other condos in my building or nearby buildings were having the smoke/steam. The employee that initially inspected by furnace (Carlos?) informed me that the heat exchange was clogged and would require me to repair the furnace or purchase a whole new unit (I opted for a whole new unit based on its age). Carlos gave me the impression there was no rush and that it was not something that necessarily needed to be done immediately. When the second employee (Dave?) came later that day to take measurements and verify the replacement unit needed, he made it seem almost emergent and began to wonder aloud if he needed to shut my furnace off that day. The stark contrast between the two was alarming and created a bit of a trust issue on who to believe. Carlos seemed a little green and Dave seemed like more of a veteran. Dave eventually determined it did not need to be shut off as no carbon monoxide was entering my condo. The whole experience did create a bit of a panic for me though, so I quickly accepted the only available appointment within the following two weeks. It was convenient that they could get it replaced just five days later, but if it truly wasn't an emergency then I would have liked a little more time to verify I was getting the best price as it wasn't cheap (to give you an idea this is the largest purchase I've ever made behind my home, education, and car). They do offer payment plans that were easy to enroll in, one of which has 0% interest if paid off within a year. I'm not trying to throw anyone under the bus, but I can tell they really want an honest review as I've received multiple texts and emails asking to leave one. The crew that showed up on the morning of 12/24 to install the new unit were quick and efficient. They were respectful of my property and explained the new thermostat to me. All the employees were friendly, including the ones running the office over the phone (Micah?).

Thanks to the flooding my hot water heater is shot! I called Thielmann (since they previously were…read moreRoss and that was the service I use to use) they came out to inspect my pilot light situation and unfortunately just the inch of water I had is the right amount needed to short circuit things. He also made sure to check out my furnace to ensure there weren't any issues with that - I knew the AC was working fine but he ran a service check on the heat as well. I am a little confused as to what's happening for the next appointment I've set up - is this to gain an estimate on a new heater or to actually install one which is the reasoning for 3 versus 4 star. Tried calling back to find out but couldn't get ahold of someone. I'd like to get a few quotes of course for something like that/have a discussion about the types of options for water heaters.

I used to love this company. We purchased a service contract with them because of their outstanding…read morecustomer service and the positive experiences we had with their technicians. Unfortunately, without any notification to existing customers, the company was sold to ABC Heating. I had a maintenance appointment scheduled months ago for today between 8:00 a.m. and 12:00 p.m. No one called or texted to let me know the technician was running late. When I called, I was met with an AI phone system. After repeatedly asking to speak with a real person, I finally reached someone, but she couldn't provide any information because dispatch wasn't responding to her either. As I write this, I'm still waiting for my technician to arrive. The excellent customer service was the main reason I chose this company and purchased a service contract. This experience has been extremely disappointing. At a minimum, current contract customers should have been notified that the company had been sold and reassured that service would continue without disruption. Based on this experience, I can no longer recommend this company.

Review for the electrical:…read more Hometown is not the least expensive. However, scheduling seemed to be fair easier with them than any other, and Shawn (the electrician that was dispatched) was a pleasure to work with, even trying to help troubleshoot a related situation (not specific to his work). Where can they improve? That's easy... 1. Clearly, you price based on the service as you should. Some tasks though should not warrant such a premium. Consider coming down about 20%. 2. The sales process - basically everything before getting an expert out - is not optimal if you're someone who knows what needs to get done and just needs "the smart one" to show up and do an assessment. There wasn't pressure; just needless extra steps. 3. I will have to make some adjustments due to observations after Shawn left; it's not his fault specifically, the home had some wonky wiring and the install had some very picky requirements where the use case is going to warrant some changes. Due to the high premium, I can't justify having him back out like I normally would. Ultimately, for electrical, do I recommend? Yes. I just think they have opportunities to improve.

The tech, "made adjustments", got the furnace to ignite, and refused to tell me how. He then consulted with his boss and returned with a $496.00 bill. This is about 3x the amount of a common service call. He added that they would apply the $496.00 to the price of installing a new inducer motor, or a new furnace. Making the installation of a new inducer motor $904.00. I spoke with a supervisor who said it was more than a service call because "adjustments" were made, and the heat is now on. I consider this very sneaky and out of line. They never told me this service call would be $496.00, or any price for that matter. It was a sneaky rip off that the consumer should be aware of. I should have paid no more than $200.00 for that service call. Future customers should be aware of this tactic.
