"Job done by this company for orofino weatherization was completely unacceptable and unprofessional, will never use this company for any job ever again. Copper lines kinked with leaks in line where kinked, wouldn't come back and repair without a trip charge being paid had to hire a professional company to fix these fly by nights screw-ups. Documented and pictures of this fiasco if you'd like to see this company's work!"

"My parents are elderly and live in Pomeroy. Guardian installed a heat pump for them several years ago. The first time it was wired incorrectly and they had to return to correct it. This winter it stopped working and they had no heat. The heat pump was still under warranty. I called Guardian after my parents said they had called several times and were "getting the runaround". I was completely shocked when the female employee who answered the phone told me that they were not going to make a special trip to Pomeroy for one customer. She explained they had no other "runs" in Pomeroy and would not respond. I would not recommend Guardian to anyone. This is an unethical and unprofessional business practice. What kind of company installs a product and then refuses to repair it when it is still under warranty? We called Up The Creek on Thain and they immediately responded and were very helpful."

Grassi has been serving the Walla Walla Valley since 1958 and is family owned and operated. We are committed to honesty, integrity, quality, pride in workmanship, and a high standard of business ethics. Our years of hard work have paid off in a business that continues to grow through referrals of satisfied clients.

"I have been a faithful customer of Grassi’s for 5+ years. They’ve installed 3 systems for me and serviced 4. I am a small business owner in town and don’t take negative reviews lightly. As of today, Grassi has lost me as a loyal customer. Over the past 6 months we’ve had consistent issues with a couple systems (5+ call outs to 2 properties). To their credit, since the units are under warranty they say they will warranty the parts. Even still we are at $1,700+ costs thus far. Today, our tenant was cold and turned on the heater. It is 60 degrees outside. Grassi is charging for another callout as the units that they worked on within the month threw another code. Their technician, Cody, called us and told us that this is an operator error, blaming our tenant for their machine malfunction, as these are “not designed to heat when the temperature outside is above 60”. These are the only heat source for the house as recommended and installed by Grassi. What is our tenant supposed to do? I don’t believe this is an engineering issue as I have more faith in Carrier (the brand installed) or my tenant, who deserves to be comfortable. My take is that this was either poorly installed or poorly recommended. When asking more questions Cody, the technician, told us that we knew nothing about refrigeration and hung up on us."

Gas Leak Repair questions, answered by experts

In North America, pipe measurements are listed as the nominal pipe size (NPS). This measurement refers to the outside diameter. As an example, a 1/2-inch copper pipe has an outside diameter of 5/8 of an inch. If a hardware store lists a pipe as having a 2 NPS, it means that all the pipes with this measurement have a 2 ⅜-inch outside diameter, regardless of wall thickness and inside diameter.

In most cases, a gas stove should be installed by a licensed plumber. Connecting gas appliances carries many risks, chief among them a fatal gas leak. If your home is already set up with the proper gas hookups, you may be able to DIY the installation (or save money by hiring a local handyperson or basic appliance installer near you rather than a plumber). If you’re ever in doubt, however, we recommend going with a professional master plumber.

You should have a licensed plumber to install a gas line for your new gas fireplace. As experts in all things natural gas, these professionals understand how to work with gas safely to avoid explosions, leaks, and other potentially hazardous situations. They also know how to handle the other aspects of the process, including pulling permits, digging trenches, and connecting new gas lines to old lines.

A few factors determine the amount of time it takes to convert from an oil to a gas furnace, mainly adding in the gas lines, updating your appliances, removing the old oil system, and installing a chimney line. These projects can vary, but you should expect them to take at least two or three days to complete.

The size of a pipe isn’t always the outside or inside diameter. Rather, it’s a nominal diameter that depends on the type of pipe. For male pipes, you’ll need to measure the outside diameter. For female pipes, you’ll need to measure the inside diameter. You’ll then need to use a nominal diameter conversion chart to get the actual pipe size you’d buy in the store.
