"We received a flyer about off season air conditioner install, and since we were interested in a separate furnace/AC unit for our 2nd floor we thought we'd get a price from Mt. Everest Air (also goes by Tiger Plumbing). Their sales representative arrived on time and to collect our information, including a summary of the problems we were having with air flow to the master bedroom on the first floor and the 2nd floor. The actual service technician who would do the work if we decided to move forward, Steve Helms, arrived a bit later to assist the sales representative in determining possible courses of action. We were provided with multiple options, including a damper system using our existing furnace/AC setup and a damper system using a completely new and more powerful (and more efficient) furnace/AC setup. The system using our existing furnace/AC setup was by far the cheaper solution, and that is what the sales rep and Steve recommended. They could have tried to upsell us on the much more expensive solution, but they did not even try. Their rationale was that if our existing system with dampers installed turned out to be insufficient, they could always install the new furnace/AC separately. The company offered no interest same as cash financing and we liked the idea of a damper system, so we went with that option, including the installation of 2 Nest learning thermostats which they'd admitted they'd never installed before. The work was to start a few days later.
We received a call 2 days before the install was to occur to let us know that a part might not come in by the install date so they might have to push back the install one day. I received a call the next day letting me know that the delay was, in fact, necessary so the install took place the following Monday. This professional and timely notification was helpful.
We expected Steve to arrive on Monday relatively early, but he did not arrive until about 11 am. I called the office multiple times as they originally stated he'd arrive around 10, and when he was not yet there I called again to get an ETA. The lack of communication on arrival time is the only criticism I have of the entire transaction. I can't ding them too badly for punctuality as they never actually committed to anything but the actual date of service, but they should have let me know about Steve's arrival time.
Once Steve arrived, he worked throughout the day without a break for lunch or dinner up until about 9:30 pm. There was a point where we would have preferred that he finish the next day, but he would have had to leave us without heat during the winter so he pressed on. I do not fault him for this as we had a relatively complicated install in that we were adding Nest thermostats that required additional setup beyond basic digital thermostats. Moreover, Steve wore booties in the house so as not to track in dirt and water from the outside and our attics. This was a nice professional touch.
Since I'd done significant research on the Nest thermostats and had a specific way in mind for their setup, I had a lot of questions for Steve. He took the time to explain things to me and he never acted put upon by having to make such explanations. We worked closely throughout the process because I wanted the Nest thermostats to control our on-Furnace humidifier and I knew we needed to connect some wires to the Nest units that were not previously connected to our old thermostat. This meant running more wires than original expected to the 1st and 2nd floors.
Although long, the install went off without a hitch. We had no issues and they system works as expected (at least respecting heat). We will not know how the AC works in the summer, but we'll revisit that when it starts to warm up and we switch from heating to cooling. I do not believe the install could have gone any faster without bringing on another technician. Steve did not work slowly, there was just a lot to get done because of the complications we requested. Moreover, Steve went above and beyond by not stopping to for lunch or dinner and by performing some additional work that was not in the original proposal. He reviewed our attic insulation and airflow to let us know if he thought we needed anything additional there. He said we were in great shape; which was another chance to upsell us where a no/low cost option was recommended. Also, he installed a relay and the Nest units that I had ordered without charging us anything beyond the original quote.
In summary, we had an overall very good experience with Mt. Everest Air. They were professional, patient and fair. I consider myself to be a relatively high maintenance customer in that I ask a LOT of questions and want things done a certain way. They took the time to answer all of my questions and performed the installation as directed and without complaint. My only issues, again, were that we never received an initial arrival time and when we did receive an arrival time the technician arrived an hour later. I understand he needed to pick up some parts the morning of the install, but better communication would have been nice as I worked from home that day to provide input to the process. I probably should have requested an arrival time the previous week, but I really should have had to ask. The timing issues are the only reason I gave the company a "C" for punctuality, a "B" for professionalism, and a "B" overall. Once Steve was on site, everything went well (considering the customer-driven complexity of the project). We were impressed that Steve could reason out the Nest system even though he'd never installed one before. They had multiple chances to upsell us but recommended lower cost/higher flexibility options. We LOVE the new system and would recommend Mt. Everest Air and especially Steve Helms for other installs.

It depends on the severity of the leak. Minor leaks may not require immediate attention and can be scheduled during regular business hours. However, if the leak is causing significant water damage or you can't control the flow of water, it's best to call an emergency plumber right away. Addressing serious leaks promptly can prevent structural damage and mold growth, potentially saving you money on extensive repairs later.
A journeyperson plumber is a licensed professional with a state-issued permit who installs and repairs piping for water and heating systems under the supervision of a master plumber. They have completed extensive training and amassed significant experience leading teams, drafting blueprints, and designing comprehensive plumbing installations. Their proven expertise ensures that they can handle both routine repairs and complex projects with precision.
