I had not used Westenn before and wondered if any emergency service repair companies would be answering during the holidays. My call was promptly answered and a service person was on his way. He even had the part we needed on the truck. We were up and running within an hour. Our property manager also commented that it was the fastest response she had ever seen. Westenn will be our new service provider and I can't thank them enough for the great after hours service and especially during a holiday weekend. Last but not least, the pricing was fantastic and so fair especially because it was a holiday weekend!

However he did say that if there was services actually performed it would have been around $600 flat fee for basic service. I thought that was a little high for replacing a outdoor faucet and parts and so on. But he was very helpful. The electrician came out and he did a wonderful job figuring out where the problem was but for the electricians they're charging a flat fee of over $400 and to assess the problem and do basic repairs. Now he assessed the problem but he could not repair it without additional costs which he estimated to be about $1500. So I still got charged but no repairs.

On October 22 2025 I had Master Services perform an annual service on my Carrier furnace. The furnace was working well with no issues but I wanted to do the annual service as recommended. Morgan the technician poked around but I did not see any of the standard procedures done like I am used to seeing from other providers. There was a tremendous sales pitch pressure from the tech spending more time on how I can purchase a new furnace from their company, even though our furnace served us well and was in excellent condition. I paid the bill and he left. Oct 24 2026 just two days after service The furnace failed to start and we were in cold weather for several hours. So I called the company back asking why the furnace is having this problem right after the tech worked on it. Morgan came back and blamed it on a blown 3A purple fuse which never happened before. He said he did not have a fuse in his truck, luckily I had 3 of those in my fuse kit in my truck so I gave him my fuses, he started switching wires around burning 2 more of my fuses and finally he got the wiring right and the 3rd and last fuse worked and the furnace started to work. He did not seem sure of what is happening or what else to check for. We had to make a trip out of state to visit family but we always leave the heat on in cold weather just to be safe and we turn the main water valve off and drain the pipes. Jan 28 2026 We returned to the house to find there was no heat in the house and the toilet tank and bowl had blocks of ice in them. The bathroom sink trap was cracked from ice and the shower valve was busted along with the kitchen sink not draining. A pipe also sprung a leak in the basement. There was also a strong natural gas odor in the house. We called again and they sent another tech Mitch who showed up with three space heaters to thaw the house plumbing out but could not get furnace started he also confirmed the gas smell to be present he said the gas coupling inside the furnace was not tightened enough from when they did the first service. He did not bother to check the ignitor but did after I asked him to check it. He said the ignitor is bad and he will call me back the next day with a price as he claimed did not have a replacement ignitor in his truck and he estimated the price would be around $600 a part that cost under $30 He left us with no heat and a gas leak while I slept in the house in the extreme cold snap in January I could have died from both the cold and the gas leak. Jan 29 2026 Mitch never called back to come replace the ignitor. I gave up and had to call ANOTHER company to get our heat working. They came over and figured the problem in 5 minutes replaced the ignitor and tightened the gas coupling which was left loose by two technicians from Master Services. My bill was $357.44 and our furnace is working well since till the writing of this review March 23 2026. Jan 30 2026 Plumber Eric from Master services came over replaced the frozen sink trap that they caused to fail from freezing and charged me $154.83 He also gave an estimate of $1700 to replace the leaky pipe that they caused to freeze up due to low quality work. I refused to do this and feel they must take responsibility and fix what they broke. I had to replace the shower valve myself and get the kitchen sink flowing again. Several phone conversation with manager Juan did not help as he insisted they have to charge me for pipe repairs that would have never happened if they did not cause the freeze. My pipe is still dripping and they totally ignored the problem. I see that a Mr. Kyle Burroughs listed as general manager on the better business bureau website so Mr. Burroughs if you are reading this Please intervene to rectify this problem. You can get my contact information from your service department records. All I need now is you send a plumber to replace the pipe section that is leaking so we can put this nightmare behind us.

I noticed it had fallen, and was hanging by cords and copper tubing yesterday. There was water leaking everywhere in the basement. I called a number of companies where I was put on hold, talked to Ai, and once, given an appointment for 5 days later. Then I found Ben at Forced Air Systems. He answered the phone, friendly as can be, asked some questions and said he could get someone out tomorrow. He told me how to turn off the water supply to the humidifier and then asked me if he could call me right back. And he did! Two minutes later. He said he found someone (Jeff) who could come today. Wow! Jeff showed up, explained exactly what the problem was, fixed it and then handed my a bill that made my day! It was the most reasonable amount I could ever have expected. This company is a jewel. IF YOU HAVE ANY HVAC NEEDS, THIS IS WHO YOU CALL! They are a small family company based in Greendale and they completely understand reasonable pricing, the need to answer the damn phone and their friendliness is clearly intrinsic and genuine.

I used Top Tier Mechanical for my HVAC needs in June 2024. I had a new AC unit installed with a new…read morecoil and line set. During the installation, the line set was damaged, property was damaged and things left a mess. He attempted to give me a 2 foot piece of drop ceiling track when what was damaged was a 4 foot section, deeming this section useless. No attempt to replace the 2 damaged ceiling tiles. On top of the damage, the unit never worked properly. I've tried multiple times to have the company rectify the situation as everything is under warranty. It was never rectified last year and as of this year, the company came out and attempted to fix the issue and it did not work. I had a friend, that's works for a HVAC company, come over and check the numbers with his meter. He did not perform any work at all on the system, simply read the number to let me know that the reading wasn't within normal range. Chris, the owner of the company, told me that he was going to warranty my coil and replace it. He has made multiple lies to me with different dates and times he come out. I made sure to set aside time from work to be able to be here for him. He doesn't show up and completely stopped responding all together. I filed a complaint with the Department of Agriculture, Trade and Consumer Protection. They have reached out on my behalf and he lied to them stating information that goes against the proof I have in all of the text messages. I have all the paper trail going all the way back to June 2024 when the install happened. It's all been through text messages and I have screenshots of everything. I'm currently without a working AC unit and had to borrow window units to get by in this heat. As of now, I am out a lot of money. I have since had an HVAC company come out and take a look at my system. I was informed, and have pictures, that the coil in my system isn't the right coil. I paid for a 2.5 ton coil and received a 1.5 ton coil. This was verified via serial number. On top of the coil being wrong size, it was improperly installed without the right size pan under it causing a major airflow issue. I have pictures of this as well. When looking into the warranty, he never registered the coil only the condenser, meaning that it is not under warranty. Regardless, it was the wrong size and I had to buy the proper coil for my unit. After having these issues I looked deeper into the company and the owner has been sued numerous times under his personal name, Top Tier Mechanical and his previous company name of Fresh Air Mechanical. It is a long list of small claims and fraud cases. It's all public knowledge, so do yourself a favor and stay far away from this company. If you do not believe me, search for yourself on the Wisconsin CCAP webpage. Thank you and I hope I saved you a long list of problems and headache.
