I've worked with John on several projects over the last year, mostly new installations, but some repair work as well. I had the pleasure of working with John quite a bit, and have been very impressed. I find myself fortunate to be able to have found someone that was able to both solve complicated issues, and do very high quality work with the installs/repairs, and all at very reasonable prices. I've outlined some projects below.
Replace Existing HVAC system:
I had an HVAC system that was almost 30 years old at a rental unit. The furnace finally broke down, and the condensing unit didn't seem to be far behind. It used the old refrigerant (R22), so replacement had to use the newer type of refrigerant (R410a). The recommended way of doing this is to replace the refrigerant line to a bigger line as part of the new install, but most HVAC installers do not do this; they simply flush out the old line and install the new system with the old line. I pressed John to just flush out the line, since replacing the line costs more and I didn't want the new refrigerant line as an eyesore running down from the second story, since it would have to be run on the outside of the house. John felt very uncomfortable just flushing the line, and ended up just replacing the line as part of the price we had already negotiated. The refrigerant line install looked very good, and was seamlessly installed so that it did not stick out and was not an eyesore. John ended up doing more work for the same amount of money just because he wanted to do it "right", and didn't want me to have any problems with the system. This is a good example of the high standard he holds his work to.
Replace Ducting:
My ducting was old and torn, not properly sized, and caused half of our house to barely get any heat, while the other was too hot. John spent time with me to fully understand the heating issues, and re-engineered the ducting (upsizing some, downsizing others, added additional) to fix our heating issues. He also installed dampeners both at the air handler, and at the registers, and even at the splits, to give very fine tuned control of the air flow. After some adjustments to the dampeners over the summer, our house is very evenly heated and cooled.
Replace Condensing Unit:
Unfortunately, as part of firing the system back up, after the foundation repair, the condenser was having issues (It was having issues before this). After some troubleshooting, John gave me the bad news that the condenser (whole outside unit) needed to be replaced (I think the compressor went bad), and since it was an old unit, it just made more sense to replace it. Unfortunately, this required removing all the refrigerant again, and redoing all the work he had just completed with connecting the system! John likes to really educate his customers (and I am very technically minded) so he showed me the steps he took to get to his conclusion. He tested every component that could cause the issue and showed me the inconsistent behavior he was seeing with the compressor. He explains everything with enough detail to where, after working with him on these projects, I can now have a semi-intelligent conversation with other HVAC guys. Although, the compressor breaking was obviously not his fault, he really felt bad about this, so worked with me to get this replaced at a very good price.
House Fan Install:
I heard about whole house fans, and spoke with John about this. He had never installed one at the time, but knowing the quality of work he does, and his attention to detail, I had no problem being his first install customer for the house fan, as I'd trust him to do things his first time more then I'd trust most other installers to do it after a 100 times. As expected he did a great job, and from a recent chat with him, he's being doing a lot of these whole house installs since the initial one he did for me.
Troubleshooting/Repairing issue at HVAC Install:
The system John installed for me in January was not working well, and not blowing cold air. John started troubleshooting, and saw that the pressure in one of the refrigerant lines was low. Instead of doing what most HVAC guys would do, and simply add refrigerant, he knew something else was wrong, since he replaced everything in the system in January, and there was either a leak, or something else wrong. After spending some time troubleshooting, he found that the TXV valve was bad. He replaced it, tested the system, but after a few days the same issue returned. Now, again, most guys would either throw in the towel and not even return my call, or start replacing other random components in the system. John was puzzled since everything pointed to the TXV again. After some further troubleshooting, and talking to his supplier, he discovered that the TXV valve he installed 2 days prior was actually a returned part that was mistakenly sold to him as new. He replaced the TXV valve again, and that fixed the problem. read more
