"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

Common signs of gas line leaks include a rotten egg smell, hissing sounds, dead plants around the area of the leak, and unexplained physical symptoms like dizziness and nausea. If you notice any of these signs, act immediately. Shut off the gas supply to your home and call a pro to assess the situation.

To ensure a steady propane supply, schedule regular deliveries with your provider, monitor usage, and consider keeping a backup supply for emergencies.

No, you shouldn't cap a gas pipe with a compression fitting because they aren't designed for gas lines and can pose serious safety risks. Gas pipes require threaded caps that create a secure, leak-proof seal capable of handling gas pressure. Using a compression fitting could lead to dangerous gas leaks—a hazard you definitely want to avoid. 

While some building codes allow galvanized pipe for natural gas, it shouldn’t be used for propane. Propane can cause the pipe to wear down, leading to dangerous leaks. Instead of galvanized piping for propane, you should consider coated copper, black iron, or corrugated stainless steel tubing (CSST). For underground propane line installation, you can use polyethylene (PE).

Even if you invested in the cost of a gas shut-off valve for your oven and other appliances, it’s a good idea to add a seismic shut-off valve as an extra safety measure. 

Gas shut-off valves for appliances are manual, meaning someone has to cut off the flow of gas. This leaves room for error, as you might not be home or might be too distracted to think about gas lines during an earthquake. An earthquake valve is automatic and will protect your home from gas-related disasters in the event of an earthquake.
