I am sorry I cannot help you. I have a similar problem of my own. I live in Vancouver, WA. My home is also only 1200 sf and do not live in an area with a lot of outside dirt. In 2005 I had new duct work all in attack area and vents on the ceiling and a Lennox two stage high efficiency heat pump installed, the heat pump has had problems since it was first installed. Since then there has been a great increase of dust and dirt in the house and an accumulation of dirt/dust especially at the ceiling vent and return vent. This was not a problem before this installation. I was preparing to replace the carpet and install home filtration system, neither of which I can afford, but the problem is affecting my son's and my allergies. My questions are: What should I have the company who installed it do to address the dust? How much should a home air filtration system addded to the current system cost? Or would a stand alone system like the one from Alen systems be sufficient? The Lennox system has had repeated problems including excessive noise especially when it is cold. When or how should I contact the company itself to address the problems. I am concerned that the shaking and excessive noise will effect the life of the system itself. I appreciate any advice you all may have on these.

Is it possible to pick a white for cabinets and trim without knowing your wall color yet?! My countertops are Caesarstone Nougat and my appliances are white! Yes. The countertops and appliances are major components in the overall "envelope" of the space you're creating. Use those as the benchmarks for choosing a color of white for the cabinets and trim throughout the whole house. To make it easier, just use the same color on the cabinets and trim. I'd use the countertops for the #1 component to determine which color of white is the right one. Appliances second most important. Becuase odds are the appliances will be replaced way before the countertops. The cabinet color/countertop color relationship is more important and more permanent. If you have a well-color-coordinated envelope of major/permanent elements, it will be a harmonious foundation to build on and it will also inform your furniture and decor choices going forward.

Cool tile! We have this size on our floors and no issues. It’s been there for 3 years. We are having the same guys install 48” x 48” on our bathroom floor and walls in a few weeks. They are very meticulous and have experience with all kinds of tile, including larger format ones. We did a lot of research before calling for quotes. When deciding on the installer, we asked for references and asked them questions on how they planned to install, what material they were using etc. That helped us get a good installer. Best of luck with your project!

My thoughts on porosity are you had better test for yourself in person as well as testing if it's real quartzite or not. If your yard won't let you test, break up with your love please.
