Awesome explanation! When I say heat pump to people, it's amazing how often their eyes glaze over...even though most of them have had refrigerators and air-conditioners their whole lives and have never asked themselves how they work. Same principle! Compressor and expansion valve (and the heat-holding capacity of a phase change; another confusing one for people). thanks for helping educate! Hardwood Floors

Wood flooring is any product manufactured from timber that is designed for use as flooring, either structural or aesthetic. Wood is a common choice as a flooring material and can come in various styles, colors, cuts, and species. Bamboo flooring is often considered a form of wood flooring, although it is made from a grass (bamboo) rather than a timber.[1] Denver Hardwood Flooring
One of the best things about cork floors is that they are environmentally friendly because cork is a sustainable and renewable resource. The natural beauty of the material can suite any decor. The structure of the cork allows for a natural comfort and softness to absorb shock. This is why use of cork flooring is a good application in areas where people will be on their feet for extended periods of time. Using cork floors will reduce noise from traffic or dropping items, also because of the structure of the cork material. The natural properties of the material make it healthy because it is not only resistant to insects, but it is hypo-allergenic. Denver Hardwood Flooring
Generally, hardwood floors need to be buffed every 3–5 years. The process usually takes about one day. Buffing refers to the process of using a stand up floor buffer. The floor is abraded with 180 grit screen on the buffer. This allows for the new coat of finish to mechanically adhere to the floor. This process works with great results as long as the floor hasn't had any waxes or synthetic cleaners. Denver Hardwood Floors

It can be sanded down and refinished five, six, even seven times. And, if maintained properly, you won’t have to do it for 20 years. Refinishing a floor may be messy and troublesome, but most homeowners learn to live with it. After all, it costs five times as much to replace hardwood floors than it does to refinish them. For some people that is reason enough. Denver Hardwood Floor Install
Price is the first obvious variable to consider. It is almost always cheaper to refinish your floor than to replace it. When replacing, you must consider the cost of the new wood as well as the installation. You can offset much of this cost by installing the floor yourself, but this is a very invasive process that requires specialized knowledge and precision. You can typically refinish a wood floor yourself, with just a few inexpensive solutions.
You may be on the fence about your decision to refinish your hardwood floors because you wonder if your floors are a candidate for refinishing. The truth is, not all hardwood floors can be refinished. Although most common problems can be addressed and fixed without replacing the entire floor, there are some exceptions. Consider the following to make an informed decision. Denver Hardwood Floor Install
Eliminate any problem spots to make the subfloor level. Sand minor humps down with a hand-held or orbital sander to make the subfloor level. To fill any dips or low spots, use a leveling compound (also known as floor patch). Mix up the compound according to package directions, fill in the dips, then pull your straight piece of lumber back and forth over the spot to flatten and level it with the rest of the subfloor.[7] Hardwood Floors
