Now, adding to the scores of five-star reviews on Airtight Energy Inspections! Stuart came to do the audit this morning and I was so impressed at his knowledge of how to improve the efficiency of our 1926 Wash Park Bungalow. He even talked me out of spending $15k+ on new storm windows, giving me much affordable options that will yield better results. In addition to all of his recommendations, he is getting me a $40 annual credit with xcel at no cost to me. Among other things, he discovered that our bathroom is venting into insulation in our attic (a risk factor for mold) and that our sunlight needs to be sealed. Will be recommending Stuart to my neighbors!

I was referred to Airtight by someone who'd used them to get a rebate on some windows. We were…read moreabout to replace our windows so I called Airtight to see what I'd need to do. The lady I spoke with, who's name I've forgotten, was extremely helpful. After spending a bit of time asking questions to understand our project and needs, she went told me that she wasn't aware of the any rebates but that she'd look into it and follow up with me. Later than evening she called me and confirmed there were currently no rebates, and concluded that it didn't make any sense for us to have them audit our home. The way she put it was roughly "we don't like to put ourselves in situations where we can't add value". I really appreciate the honestly and extra effort she made.

We got four different drywall quotes from well-rated businesses, and innovative solutions was on the low end. It made me a bit nervous going with one of the cheapest, but they were professional, well rated, and scheduled right away. I was so pleased with the work. They came when they said and got the work done quickly. The salesperson and the workers were all very polite and considerate. Since I was working from home at the time, they took the effort to do a room near my office when it wouldn't conflict with my meeting schedule, and they put the air compressor in the garage where I wouldn't have to hear it even though that took some extra effort too. The quality of their work was excellent. You would never know we had repairs done, and the texture matches the old work seamlessly.

I want to alert the public to the unscrupulous actions of this Lakewood-based company…read more A year ago a serviceman from Walrath Heating and Air Conditioning alerted me that my 20 year-old furnace was on its last leg. He suggested that I plan to save $6000 to $7000 for a new one this fall. In November I met with a Walrath salesperson who evaluated where the furnace was located in my crawl space and advised that the price would be $8000. Two days later his written proposal came in at $10,000. When I asked him about the difference, he said that he had forgotten to add in how labor intensive my particular installation would be. He was certain it would go into a second day. I took him at his word. It took the workmen less than 6 hours to complete the job. The salesman and head of the company - now called Walrath Mechanical - refuse to talk to me about the $2000 extra I was charged for labor that was not required. This is a scam. I have since noted on Yelp that I am not the only reviewer of Walrath who trusted a grossly inflated bid. These guys are crooks. Homeowners like me and managers of commercial properties may have once appreciated this small company. Don't be fooled - they no longer care about you.

Once upon a time, we played the "pick a random number" when our outside air conditioner kicked the…read morebucket. We were extremely lucky in that we picked KCA. They explained our options & answered all of our questions. That included pricing options. They were lower than we expected. Once we weighed the options & made a decision, the new unit was quickly installed. I'm guessing that was about 5 years ago & we haven't gone a day without it since. Over the years, we've called KCA for various reasons. The contractor we hired to finish our basement destroyed our air purifier. Working with the basement contractor was a nightmare, so we gave up and called KCA. They were understanding and guided us in the right direction. They didn't try to up-sale us. They did the same thing as before. Educated us to where we were able to make an informed decision. The new unit has been great. It's in the basement, but when I'm down there and hear an electric snap, it feels good. Along with the air purifier, we decided to cross another item off of bucket list. A whole house humidifier. Installing it required moving the water heater & possibly the main furnace. They did a better job than the builder. We've lived in our house for around 16 years. 1st owners. We visited in while under construction. Small things are creeping up, The fan in our furnace went out over the past weekend. A call to KCA and we were back in business in no time. In fact, the responding fixer/installer was the same guy that repaired our air purifier and installed our whole house humidifier. That had to have been at least 3 years ago. Seeing a familiar face, knowing that he does excellent work, along with knowing that KCA takes care of their employees to the point of retaining a highly skilled staff confirms that we picked the right random number so many years ago. We're watching a new house that's under construction. I can guarantee that one of the first things we plan on doing is install 2 more air purifiers as the house has 2 systems and at least 1 humidifier. There is no question about who we are going to contact.

Where do I start. This company was hired by the seller of our new house to clean and service our…read morehvac during our sales transaction. The only cleaning they did was of the seller's wallet. I had a lengthy conversation with the owner Jared who actually had the nerve to say that well sometimes they will miss some spots. (See my photos and decide if that was "some spots.") Jared actually had the nerve to attempt to discredit our new Hvac company who is very reputable in the industry and around town when our AC went out completely after only being in our new home for 1 month by saying that we didn't need to replace the condenser like our new HVAC company had strongly suggested and another HVAC co that came out also said was necessary. The funny part about it was Jared had actually never been out to our house to even assess the broken down condenser and broken furnace part that our HVAC company said needed more than just repairs. Jared simply wanted to do a mickey mouse patch work job and then have us call him back in a year when the condenser and furnace would fail again because it was not replaced in the first place which would have been the proper way to handle it. Additionally, Jared became very defensive on the phone and when I asked him how can you say that the other HVAC company is wrong when you have never actually looked at our broken units? He stuttered and became silent. Very unethical company. Stay far far away. You will be sinking money trying to do little repairs that in the long run will cost you greatly.
