"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.

"Tech was punctual and friendly. Diagnosed the issue with the switches and outlets. Replaced half of the switches and the outlet repairing the problem. Unfortunately the new switches and outlet did not match the previous color leaving me with 2 white switches and two almond switches in the same bank of switches. Tech told me they could not make them all match because they don’t carry almond color switches. Completed after work survey and was contacted by customer service who stated that they would have a tech come back to the house and install the new white switch that i had purchased due to the inconvenience. New switch was installed without issue."

"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."

"They were prompt and they were able to get it fixed quickly. Their pricing for the parts they used was expensive, but I was satisfied with their service."

"It went fine. They were friendly. There was no additional charge apart from the big deal but he said there were close to having an extra charge because the vent line was longer than expected but it was just in the parameter. The scheduling was fine."

"The man who came to my house to describe the furnaces and help determine which one I wanted could not have been more wonderful. He was helpful and efficient. We had agreed on a week when the work would be done. The installers called and wanted to come a week earlier. I okayed it, but it wasn't the best day for me. They were nice and efficient. The new furnace appears to be exactly what I wanted. However, the new thermostat control was a different size and shape from the original one and they didn't patch the holes or repaint the edges--not a big deal but when I got a security system a few weeks ago, they did do all that finishing."
