"I was told by another company that they no longer serviced the pellet stove that I had. I thought it was gonna have to buy a new one. So I called American heating and cooling and refrigeration. They came out less than a week. Had to order the part and came back and installed it. Aaron did an awesome job. It was thorough. He explained things to me and I was very happy with the service that I got. I will be using them if I need service again. Very friendly and professional and knowledgeable."

"My air conditioner was not working so I contacted my home warranty service and they sent a local company representative to checkout the problem. It was a capacitor - the technician installed the part and it has been working ever since."

Installed a new tub and shower enclosure, added a more modern curtain rod and put some much needed paint on the ceiling and on the fire pipe running through the center of the room.
Updated the sink, tile, toilet, and tiled the floor and added an accent trim with the blue backsplash tile.
What we started with, sewer soaked carpet, drywall, trim, yuck.
Before, this isn't bad and shows this dryer has had routine cleanings and repairs.  Not bad but we thouroghly clean each and every one we do a belt on, and can take that dryer a part just to clean it.
Plumbing failure, led to a cute remodel.

Bathroom Fan Installation FAQs, answered by experts

Before committing to this new project, you’re likely weighing the pros and cons of attic fans. The good news is that typical roof vents can only ventilate 150 to 300 square feet per unit, whereas a single attic fan can circulate enough air to vent an entire attic. By moving large volumes of air within and out of the attic space, an attic fan can lower the temperature by 15 to 40 degrees Fahrenheit and reduce moisture to prevent mold and mildew.

Fan power is measured by CFM, or cubic feet per minute. For every 1,000 feet of square footage in your attic, you need a minimum of 700 CFM. Steeper roofs may need larger fans or about 840 CFM.  You can figure the size of attic fan you need by multiplying the square footage of your attic floor by 0.7. (multiply by 1.2 for a steep roof and 1.15 for a dark roof). That number is the CFM required for your fan to run efficiently.

Once you remove all standing water and puddling, you should run fans for 24 to 48 hours to remove the remaining moisture. For severe water damage, it’s a good idea to run them for three to four days to be safe. Make sure you buy or rent the proper size and number of fans for your water-damaged area.

While ceiling fans shouldn’t get loose over time, they still can—especially if they’re installed incorrectly. A wobbling or tilted ceiling fan can shift the screws out of place, causing it to loosen and become a fall risk. It’s important to tighten screws and balance blades as soon as you notice that they’re misaligned or uneven to prevent the ceiling fan from loosening further and becoming a hazard.

When maintained and repaired when necessary, your whole-house fan can last between 10 and 20 years. Check your warranty when purchasing the unit, as it will typically only cover between 5 and 15 years. Its longevity will also depend on your local climate and how much you use the fan. Having a professional size your fan appropriately for your home size will also help ensure it doesn’t get overworked, which can limit its lifespan.
