Great experience getting both my annual furnace check and my new air purifier installed. Jeff was efficient and respectful, I appreciated him taking the time to answer all my questions and giving me recommendations for my home. Thank you Northwest for getting us ready for the cold to come!

Had a great experience with the plumbing division and decided to switch our heating and a/c to northwest. Received an appointment for afternoon to service our four units. Waited until after 3 and called to find out they weren't coming because they were under staffed. Rescheduled for two weeks later and same thing happened. No call telling us they would not be coming.

Apparently not really interested in new business. Will try someone else. After a conversation with Bill D., I gave Northwest a 3rd chance and they delivered. Alex showed up on time. He was easy to work with, pleasant competent and efficient. Expect to see them again in the fall for furnace maintenance. Thank you.

Couldn't imagine a better plumbing company. I broke a weld on a pipe while trying to remove a washing machine hose and found myself with no water during peak AC repair season. I had 2 brand new wash machine water supply valves installed within 3 hours of calling and my bill was very reasonable considering the work that was done.

Joe fixed several drains and replaced our sump pump. He did an awesome job and went the extra mile with cleanup. He was very professional! We plan on using Northwest for all our plumbing problems!

Northwest Mechanical repaired a drain and installed a new hot water heater. I was very pleased with the work. Jake did a great job on the heater and Joe was awesome with the drain! Highly recommend.

On January 2nd, we came back from a trip to find a frozen pipe that ended up bursting. Northwest was one of the only companies that offered to come immediately. They did fast efficient work, and the guy was very friendly. About two weeks later we received a thank you card for our business. The card was a nice gesture. THANKS NORTHWEST!

Our air conditioning unit quit working in this heat wave and I was happy when they said they could come out the next morning to look at it. I was ecstatic when they called back later that day because they had a cancellation and could be here in 10 minutes. He diagnosed the problem right away, it was still under warranty, and it was fixed and he was gone within 20 minutes. Great service!

10-20-16 We called Northwest Mechanical to have our furnace system (hot water boiler) checked out for winter. They were very accommodating and Mike Perkins came to check it out. Mike was very knowledgeable of the system and very accommodating to us as customers. He serviced the system and set everything to specs. Mike's work was very satisfactory. You can count on us as return customers and referring others to Northwest.

The night before I was leaving for vacation, I found a pinhole leak in the main water line into my house. It was 9 o'clock at night and I had no other options but to call a serviceman. I called Northwest Mechanical and they promptly sent out a tech. His name was Jeff and he not only fixed the issue within 30 minutes, but he was also very personable. This saved my family vacation from being postponed and made my wife very happy. Hats off to you guys for doing great service! I will call on you in the future.
