Our home warranty sent Willie out on Christmas Day to fix our furnace. He was prompt, professional, fixed not only the issue but had suggestions to make the system more efficient (which did, it runs less often now and heats better).He also fixed the issue faster than the previous company took to mask and band-aid the issue.Very pleased. We have already referred Willie to neighbors. Its great to have a company we can trust!

Willie installed a whole home humidifier for us and was kind enough to point out some issues with our newly installed HVACR system from a bug company in town that didn’t have much attention to detail to help us save on some costs. Willie is wonderful, very prompt, does great work, goes over everything, is efficient and did everything at the best price I could find in town. Very kind gentleman and even checked in a few days later to make sure everything was working to our liking. 5/5 stars!!!

Excellent service, tech went above and beyond to fix our 90 year old boiler. Very knowledgeable and resourceful, he found the needed part that was in West Virginia and got it here fast knowing our house was getting colder by the hour. Exceeded our expectations, very fairly priced as well. Even sent us a follow up text just to make sure that we were comfortable. Also advised us on how improve our existing system. Highly recommended.

Willie (Gold Star HVACR owner) is a very knowledgeable HVAC professional. We had a central AC installed in the early summer that didn’t work to full capacity and we asked a lot of other HVAC professionals about potential options to fix it...without any luck. Willie provided a different perspective about the evaporator coil, valve, and refrigerant adjustments to improve our system. We trusted his judgement throughout the process and his fixes worked—we were amazed with the final results! His understanding of HVAC is invaluable and in this industry with a lot of competition, it was great to work with him. I highly recommend Gold Star and Willie for any complex HVAC service needs in Madison and the surrounding area…we will definitely stay in touch.

Willie was excellent ! I would highly recommend him to anyone needing HVACR service! He is extremely knowledgeable and friendly; he walked me through what he saw and explained what the situation was and why it mattered. He ended up needing a little extra materials and didn’t charge more. Excellent and cost-friendly service and my home is toasty warm!

Willie is the real deal! I had a complicated thermostat issue that needed to be fixed. Really impressed with his professionalism, quality of work and persistence. Thanks a lot, Willie!

This is really knowledgeable and professional company. I was doing mini splits throughout the house and was lucky to pick this company. Will be having them for my next projects.

Our experience for the last 3 times has been excellent- the quick response, thorough cleaning, repaired the furnace and created a tighter seal to increase efficiency. We even found extra silver duct tape so we ours use it when we replaced the air filter the next time. He shared how to wrap the duct work and provided low cost options. Very impressive and always super friendly . We highly recommend using this company!

Willie went above and beyond what some other businesses would do. He didnt just install a new AC unit; he made little fixes along the way that would improve the efficiency of my whole system. Its that type of attention to detail that you want from someone doing a major job on your home. I found myself spending a bit more time around the job as he offered explanations and shared knowledge as he worked. Im already planning my next project with him to install a humidifier before winter.

Willie did a phenomenal job! He was very professional, timely, and provided a quality service. Willie was also friendly and spent the time to explain his craft. I will definitely use his services again. Top notch!

I enjoyed working with Willie and would recommend him to anyone looking for an HVAC specialist.

Willie was awesome! Super knowledgeable and worked quickly. I found him on Nextdoor. He responded very quickly and was able to do my job within a very timely manner. I cannot speak highly enough of Willie and Gold Star HVACR

The contractor was very unprofessional. He yelled and swore at me on the phone, during a conversation about the timelines for the furnace equipment order. He did not have a clear understanding of the process between American Home Shield and himself, and repeatedly pointed blame at AHS saying that I was their customer, not his and therefore all concerns and questions should go to AHS. (I had an explicit conversation with AHS where they assured me that is NOT the process) The conversation got so bad, that I had to hang up. Being in customer service myself, I tried very hard to have a rational conversation with him. After I calmly told him his customer service skills - his demeanor and his tone, his swearing, were unacceptable, he became belligerent. After this conversation, he completely cancelled the entire service request with no communication to me. After 2 weeks of Wisconsin winter, Im STILL without a furnace, and am now going through the entire process again with AHS and a new contractor theyve assigned.I would not recommend this contractor, nor would I feel comfortable with anyone who manages their emotions so poorly being in my home, as I would be afraid they might become violent if I said something they didnt like. Unacceptable behavior from a business owner who wants to stay in business. There is literally no excuse for yelling and swearing at someone youre providing a service for.p.s. reading the other reviews, looks like this is a pattern for Willie Mallard.

Willie is very knowledgeable and willing to share it including tips to keep things working better longer. He was able to make me feel assured that my problems would be addressed quickly and his communication was excellent.. He even checked in a few days later to make sure everything was going great! Id recommend starting here for all your HVAC needs and you wont be disappointed.. Im also a repeat customer and I know they care a lot about that!

Gold Star Willy Mallard was very prompt with his work response. He worked very efficiently and thoroughly, and explained what he was replacing before doing so. He cleaned up the work area, leaving the space as he found it. I highly recommend him.

Very happy with the service and support that Gold Star was able to provide. Local owner and operator, professional level of service.

Completely unprofessional. I spoke with a man who actually swore at me and yelled at me because I wasn’t patient enough to wait for his callback. I’m sitting here with no heat and I called him three times leaving one voicemail never getting a response until 40 minutes later. Do not use the service!The owner just called me back screaming at me swearing and using homophobic comments. Completely unprofessional.

Willie, the owner, is amazing. He is extrememly detail oriented and takes pride in his work. He went above and beyond in our situation to make sure the job got done right. He is an excellent communicator. We had an issue with our heater and he was at our house within 2 hours to fix it.

I learned more about home heating in a short conversation with Willie than Ive absorbed over more than four decades as a homeowner. He did an incredibly thorough cleaning/tuneup of my Carrier furnace. (I have never had a furnace tech come in with a shop vac before!) He also cleaned out my gas fireplace, which runs noticeably hotter and brighter now. I would recommend Hvacr absolutely without reservation.

Willy made a emergency house call with a remarkable response time of minutes. I explained the problems in the bathroom. He talked through what the problem actually was and offered a solution. Very professional to say the least. Long story short, problem solved for a reasonable rate. I recommend Gold Star to my neighbors. I will call again. *****

The problem was explained to me in terms I could understand. I was given two options for a fix, short term and long term. They cleaned up after themselves.

Very reliable and he knows his stuff .ac has never worked better. The duct cleaning and sealing will make all the difference as well

Thank you so much for working on my unit. What a difference you made . Your prompt response was a bonus. Fast diagnosis and repair. Great job

Willy arrived on time. Showed him my furnace and he went right to work. He cleaned the intakes and adjusted the flow of gas. My WeatherMaker 8000 is working more efficiently.

Very thorough, punctual, detail oriented, went above and beyond the usual and customary service. we would call them again for any service they provide.

Thank you for the great work! I would highly recommend you to anyone looking for heating and air services

The fastest and friendliest service I’ve had that I can remember! After being recommended by my mom, I’m glad I made this call!
