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."

Customers say: Super punctual
"I purchased a dishwasher and an above-range microwave from Costco, both within a few months of each other. (Rats chewed up my former dishwasher's wiring and ruined the whole unit.) On both of these installations, my experience with A-1 was nothing but very positive. These guys really know their way around kitchen appliances! They had some issues with removing the old microwave, but Cole figured out a workaround and managed to get the thing out. Our only real issue has been with Costco, because the store doesn't bother checking with A-1 before setting a delivery date. Then A-1 has to change the date because they're backed up. That glitch is all on Costco, not A-1. We've had many contractors and installers in our home, but A-1 is the best! You can count on them to work quickly, efficiently, and carefully. They're very courteous, too. God bless A-1 Installations! (I wasn't compensated for this review, by the way.)"

Gas Leak Repair questions, answered by experts

The cost of repairing a gas leak depends on the type of leak, its severity, and how difficult it is for the repair technician to reach it. Some of the most common gas line repair costs, on average, include:

  • Cap a gas line: $75–$150

  • Gas system inspection: $150

  • Pressure test: $75–$500

  • Damaged or corroded pipe: $6–$7 per linear foot

  • Repair gas leak: $120–$5,000

Capping a gas line costs approximately $125. The final price varies from $75 and $150 depending on your contractor’s hourly rate. To completely remove a gas line and cap it at the base can cost up to $250. Most contractors will charge a flat fee instead of by the hour since capping is often part of a larger project.

Appliances typically connected to a gas line include gas stoves, water heaters, furnaces, and gas fireplaces. Essentially, any appliance in your home that uses gas needs to be connected to a gas line, which connects your home with the main gas line owned and operated by your gas company.

No, you shouldn’t leave a gas line uncapped because it can allow gas to escape into your environment, which can lead to fires, explosions, and health hazards. That’s why it’s critical to properly cap and seal any unused gas lines as soon as you can. If you’re not comfortable with that, you can always call a licensed plumber to safely handle it for you. 

A plumber or certified gas technician is responsible for capping gas lines. Gas lines require expertise and understanding of safety standards to ensure it’s properly sealed. Your local regulations may also have specific requirements for capping gas lines.
