One of those jobs that are always deferred is cleaning the gutters and I do not really want to go…read moreup there myself. I called them to install gutter guards so that I would not have to do it so frequently. They inspected the gutters, told them how the guards would fit, and fitted everything in a single visit. It is a fairly easy upgrade, but it ought to simplify things in the future, and they left everything tidy.

Having spotted a small water stain on the ceiling, I made a decision to arrange a roof check-up to…read moreexclude any severe problems. The team came at the agreed time and described every step prior to commencing the assessment. They inspected the surface and made notes on the areas that might need to be addressed in future. The report was given soon after the visit and it was well defined recommended maintenance as opposed to insisting on immediate repairs. I liked the fact that the explanation was simple and easy to follow. The problem was minor, and this provided me with some relief. In general, the visit was well-organized and professionally managed.

No one wants to have to call an AC repair company, especially in the Texas summer heat, but if you…read moreneed to, call Nicks. The fan on my outside unit stopped blowing and after failing to diagnose the problem myself, I called Nicks. Great customer service upfront and I got the incredible Chris to come out and help. Turns out the contractor failed and Chris, being his amazing self, showed me what was wrong, how he figured it out, and more. I honestly cannot recommend Nicks enough. They're honest, kind, and fast, and will continue to be my AC go-to's.

Important note: This company was bought by Dunrite Heating and Air. Please read their reviews…read morebefore calling this company. Sadly, the owner of Nick's passed away and this company is now owned by Dunrite. I called that company based on the reviews of Nick's Air Services, but their services has definitely NOT been the same as mentioned on this profile. In summary, this company is expensive, can make improper recommendations, and the office is very difficult to get anyone to call you back. I absolutely would not use them again in the future and - had I read their Yelp profile for Dunrite Heating & Cooling - would never have called them in the first place. My experience: My air conditioning due to leaked refrigerant due to another HVAC technician not correct. Nick's/Dunrite came out during the same day and quickly identified the problem. There was a leak on the schrader valve. They got us back to running - for nearly $200/per pound of refrigerant. 5 lbs = about $1,000. Wow, but we had no choice as my original installer was not available. Our unit has not been keeping up with the 90s for the past two months and the technician recommended 3 different options. I chose 2 of the 3 options: a larger return air duct AND repairing the plenum. I was anxious to get the work scheduled and it took me hounding them to get them to schedule the work. Communicating with this office was very painful. I would never get calls back and would just get a text message indicating when they had scheduled the appointment. Their front desk support was exceedingly helpful but not empowered to do anything besides schedule appointments and pass along info. I finally had the appointment and the technician went to the wrong address. I got a call from them saying they had been at my house and then they proceeded to the next job. I spoke to them and learned they were at the wrong house, but could not turn around to go back to my house. I had to wait until the following week to get the appointment rescheduled. What a disaster. It got worse. The work was finally done - the return air duct and the plenum. I waited a couple of days, but there was NO change in the air conditioning. I called them back again and they scheduled another technician to come out. The second technician came out, a more senior technician, who confirmed that the unit was undersized and "working as it was designed" to cool at 75-76. I don't know a single person who is comfortable with 75-76 in the house when the outside is in the 90s. I called customer service again. When I finally got someone, I got a call from William, who is their most senior technician (an older guys in his late-50s probably). He came out with the original technical and instructed him how to properly do a heat load calculation. They determined indeed the unit is undersized and I needed a 3 ton. I called back the customer service asking for a refund to the work. I've called at least 3-4 times, each time speaking with a very nice person. However, I've still not been called back. What a disaster. I've finally had to resort to filing a complaint with my credit card and disputing it through them. It's unfortunate and I didn't want to have to do this, but - when no one will call you back - it's very very hard to trust this company to make things right.

I really wanted to give Koala Insulation of Dallas a strong review because the initial experience…read morewas solid. The sales process was smooth, expectations were clearly set, and the installation crew was professional and easy to work with. Unfortunately, that's where the positive experience ended. I originally brought them in to address major temperature differences in two rooms. I was told there was a gap in insulation and that spray-in insulation would resolve the issue. Based on that guidance, I moved forward. The problem wasn't fixed. Since then, I've spent the past two months trying to get a response. I was told they would look into other potential causes, but I've received little to no follow-up despite multiple attempts. That's the biggest issue here, once the job was completed and payment was made, communication dropped off entirely. I don't expect every solution to work perfectly the first time, but I do expect a company to stand behind their recommendation and stay engaged when it doesn't. If you're considering them, just be aware: the upfront experience may be strong, but post-sale support has been very disappointing in my case.

I was particularly impressed with the communication, informing us who would be arriving and when. The crew showed up on time, did the work in the time estimated, and left with no sign there had been there other than a fresh blanket of insulation. If you need insulation, you can't go wrong with Koala.
