I'm Peter Harris and I am the owner/proprietor of Simple Works here in the Gallatin Valley. I specialize in home renovation with emphasis in kitchen and bathroom reworks. Simple Works does both home and commercial remodeling, small scale and large. I work with other business owners around the valley who, combined with my skill set, can get any job done! I enjoy meeting people and making their vision come to life through the renovation work Simple Works does. Call or email to get your project started today!

"The work that Peter did was good, but when we asked him to estimate a replacement for a water heater, he quoted us around $6,000-$7000 and then sent the final paperwork over at $9200. When I asked about the discrepancy, his response was “he wasn’t sure because he didn’t write it.” That seemed odd because he owns the company. He refused to answer any more of our polite emails asking about the water heater. We would expect more professionalism from someone we used in the past and paid money to."

Heating and Air Conditioning questions, answered by experts

Here’s how AC professionals will clean your AC coils:

  1. Unplug the AC unit or turn off the breaker to the unit in your circuit breaker box.

  2. Remove the faceplate.

  3. Spray a vacuum hose attachment or compressed air can to remove debris, dust, dirt, and grime.

  4. Use a soft-bristled fin comb to remove stubborn caked-on debris.

  5. Use the vacuum hose to suck up any extra debris.

  6. Take a coil-safe cleaning solution and spray it onto the coils. Try to choose a no-rinse solution.

  7. Let the solution sit for at least 15 minutes.

  8. Gently wipe away loosened grime and debris with a microfiber cloth.

  9. Reattach the faceplate, plug in your AC system, or turn the breaker back on.

The first sign you're not getting enough return air is if some parts of your home feel hotter or colder than others. If nothing else is causing that, leaky air ducts are your next clue. If the air pressure feels different in every room, this is also usually a sign of insufficient return air.

Most HVAC companies recommend against setting your AC below 70 as it could freeze up the system and cause more problems. Regardless of how hot it is outside, there is generally a 20 degree difference between the outside and inside temperatures, so even if it’s 100 degrees outside, your AC will likely not be able to cool your home to 70 degrees.

A 3-ton AC unit is probably too big for a home that’s 1,200 square feet. If you have a 1,200-square-foot home, you likely need a unit that’s somewhere around 1.9 and 2 tons. An AC unit that’s too large will be really inefficient and cost you a lot of extra money on your bills. 

As mentioned above, not all HVAC Schrader valves are necessarily the same. While the valve core and pin or spring size on Schrader valves used for HVAC are generally similar, the valves are not all universal and interchangeable. The size of Schrader valves varies depending on whether it's used in an air conditioner, bicycle tire, or motor vehicle tire.
