The work was not cheap but the quality seemed good and certainly worth doing after our crawl space had a few rodents intrude. We have noticeably improved airflow in the house and hopefully removed the opportunity for future intruding rodents to access and damage the ductwork if they happen to get inside the crawl again.

We had a 2 ton heat pump installed in our house that only had electric forced air heat. The removal of the old and installation of the new came together flawlessly. They designed the system perfectly. Every room in the house is within 1-2 degrees of the setting on the thermostat. We plan to add a dual head split unit at another house in January. I will update this then.

I called Denali of course they are always our go to heating and cooling Guys considering we have used some of the other companies locally )Never again!!!) Denali is our go to. We have been having Denali coming to our home for years. Ryan was sent to our house he did his thing and found the leak and was able to get us fixed and back up and running in a day. Ryan was extremely informative and efficient. Ryan was able to explain everything and give us quotes depending on what we decided to do and I appreciate his knowledge and thankfully for being very fast in making sure we don't roast this Summer inside.

Andrew is an honest HVAC technician and standup human being. I worked in HVAC wholesale for a few…read moreyears and got to know the majority of companies in the area. There are only a handful you can trust, Andrew being one of them. Whether you're doing a new instal or need a repair, you owe it to yourself to get a quote from him. That is if he has any availability haha. I had an issue last year with my A/C. Had a company come out right away and the tech tried to sell me on something that I didn't even need. Finally was able to get AC NW out , and the rest is history. Andrew was able to fix it, without over charging me or upselling me on things I do not need. He's a dying breed in the trades industry. Worth every penny!

My dad ran his own construction firm for years and is a very honest guy. Talking with Andrew reminded me very much of talking with my dad about how to proceed with various projects around my home. He was competitive with the price, and I think it was very fair. I will have him out at servicing time, or if repairs do come up. He is not the biggest company out there, but he is the best. Doing business the way it used to be gives you the information to decide. I knew everything was going to go 100% issue free. From my first contact with him would recommend him to friends and family.

I have used this company twice now. First time was a heater problem (12/09/2010). Then yesterday…read more(6/05/2016) my AC went out. Luckily I found their cancelled check from 2010 so I could call them for the AC problem. The lady that answers the phone is very nice and listens intently. She even looked me up in their system from 2010. I was still in there. Anyway she promised she would have a tech out to my house the next day. He was at my house by noon and called ahead to let me know he was en-route. That in itself is amazing. Don arrived and I described the problem. He knew what was wrong immediately. He checked for the problem and showed me. Corrected the problem in less than thirty minutes. I now have a nice cool house again. Many thanks to B & M. You have a great company, and you have my business in the future. Their prices both times were more than fair. That's the reason I wanted to use them again because they were fair the first time. I wouldn't hesitate to call them again.When your heater or AC isn't working things can be miserable, or usually the wait time for a service call is forever. I'm glad to see there is a vehicle available to let others know what a good company these people are. These days there are a lot of businesses out there that just don't care. B & M is top quality for response and repair and price. Can't say enough good things about them. Remember they need to make a living just like you do, so don't expect free service. Just expect to pay for the technology you don't possess and their expertise which are worth every penny. Both are exceptional. AC and heating problems can be expensive, and sometimes not. This company will guide you the right direction. So glad I found their phone number after all those years. I guess basically what I'm telling you is I trust them. As apprehensive as I am that speaks volumes. Just ask my wife. Anyway thanks B & M. Your the best. Respectfully, Bill R. Kalama, Washington

This summer I turned it back on again, it ran for a couple days and started leaking again and I thought, huh, this is weird. So instead of calling for a service fee, it is the weekend I went online, went to YouTube,and saw how to take the thing apart. I noticed that the drain tube for the condenser was not hooked up to the drain PAN. So every time it was working, the water wasn't going anywhere, except for down the front of our wall. Anyway, long story short, I'm sure it was just to skip over, but if your unit is dripping, take it apart and make sure that the back of the drip PAN is hooked into the condenser water line probably using wrong terminology.

I called Renaud and they picked up on the first ring. A service tech (Gary) showed up at our house in Kalama within 45 minutes. He diagnosed the problem within a few minutes: a blown 3 amp fuse in the furnace blower section (in the garage) caused by a frayed wire in the bottom of the condenser unit (outside the house). He took the lid off of the condenser unit, climbed inside, repaired the damaged wire; all while it was raining. He replaced the fuse, and we were back online in less than 30 minutes. The service call and work was less than $300 and we were very pleased with Gary's professionalism and expertise. The price was affordable and we're grateful to Renaud.
