"Guardian Heating and Cooling was very professional putting in our new boiler system. Steve was on time, explained everything that was going on, answered any questions about the project, was efficient professionally, and left the area as if there was no work that had happened there. In my opinion an A+ service."

"Politely said, Sparky is the boss.
We needed electricity and HDMI ran from a cabinet in our great room up above our fireplace so we could mount a TV. Also needed cable and electricity ran to a wall in our master bedroom so we could mount our TV on the wall.
Sparky showed up on a Friday afternoon, five minutes early. Assessed the situation, and before he left, said he would look into how much parts/etc would cost, and he would call me with a bid. Sunday night I received a text from him with a bid, we set up a time for him to come for the install on 8/22 at 9am.
Sparky showed up at 8:59, and got to work. I came home from lunch to outlets installed where I had asked, cable ran, everything was great. He could not find the specific outlet cover for AC / Cable, but it will not be visible once the TV is mounted, so it is not of real concern.
I was a little uncomfortable mounting the brackets for our TV on the walls, as the studs were located in odd places - and I didn't trust myself to mount a $1,000 60" plasma anywhere that wasn't on a small stand. ha!
I asked if he would mind installing the mounts if I kicked him some extra $$, and he gladly obliged to stay longer than he had originally intended. He even went so far as to use his own screws/mounting bolts that were FAR superior to the ones that were provided in the kit.
Couldn't be happier. Should we plan on doing any other electrical work / lighting in the future, Sparky will be our first call.

"They came out and looked over the A/C unit. I told him it makes a very loud banging when it starts up and that the company who installed it told us that was normal and it was working fine. Once he was done cleaning the unit, he went to restart it and it tripped the breaker. So he took it apart and found that when it was installed, someone had pinched a wire, cutting the insulation and causing it to short out on the frame of the A/C unit. He fixed that, reassembled the unit and restarted it. It's still a loud start, but not nearly as loud as it was. He informed me that our A/C is a builder grade model and unfortunately it's not the best on the market so it's going to be louder than we would like. Once he was done working on the A/C, he came in and took a look at our furnace to make sure it wasn't hooked up wrong also. Definitely will be calling on Faithful again."

"The installation of the new furnace was good. We have not had any issues with it. The workers were pleasant to deal with. The salesperson was helpful and advised me what furnace I should install. I was happy with the service by this company."

"The service seemed pretty superficial, with a couple of passes in the dryer vents. Then the tech tried to sell us another service (cleaning all home duct work). I felt like it was a bait and switch, which I do not expect from Angie's List providers.

"Very prefessional and thorough. Left my place clean after the install, and even loaned me some goo-be-gone from their toolbox for a project that I was working on while they were installing my furnace. They reviewed what they did at the end, and gave me a card so that I could call with any issues. Would highly recommend Sears and their contractors."

"Jim is local. It went great. Jim Ferrell is a professional of the highest caliber. Responded quickly, took care of my problems, and advised me as to better means of protection than I had. He came back a second time to uninstall software that I purchased that did not provide adequate protections and installed free software that would do the job. He did the work through remote connection, but is available on site if necessary.
For those people needing help on getting red of malware, viruses , etc. on your computer, Jim is local, better than all thse remote out of state location providers, is a mature, highly trained professional in this area.
If you go to local computer stores you get very young people that can do a basic job, but are no where near the professional level of Jim.
I highly recommend Jim to anyone that needs these type services.
