Kowalski heating is the best contractor I have worked with. I had a particularly difficult problem with heat and cooling in my master bedroom. I called multiple HVAC companies, most of which didn't answer their phone or never got back to me. I never had any issues getting in touch with Kowalski. They always answered there phone and were happy to talk though my problem. Their technician Andy came and spent a lot time with me troubleshooting the issue. Once we figured out what was going on the owner, Jason, came and walked through potential solutions. I ended up installing a mini-split system which has worked perfectly so far. The installation was fast and the whole process was very smooth. They are now my go to company for any HVAC needs.

We have been using Kowalski HCP for a few years. All of the personnel from the owners, the office staff, Amy, Jaison from plumbing, and especially Andrew, our HVAC technician are so helpful and easy to work with. Amy makes scheduling and billing so easy. Andrew and Jaison are extremely thorough and explain exactly what services they have provided and are so willing to answer all of my questions. All are extremely polite, kind, respectful and always go above and beyond. Without hesitation, we highly recommend Kowalski HCP and are so fortunate to be one of their customers.

Title: Stellar HVAC Service by Kowalski: Friendly, Thorough, and Knowledgeable! Review: I'm thrilled to share my amazing experience with Kowalski HVAC, who recently replaced my furnace and air conditioner while also moving the condenser and its electrical components to a new location. Let me tell you, these folks are simply fantastic! They not only did an incredible job but also impressed me with their friendly and knowledgeable staff. Right from the start, the team at Kowalski HVAC won me over with their politeness and approachability. They were genuinely interested in understanding my needs and concerns, taking the time to listen and address every question I had. It felt like talking to friends rather than just service providers, creating a comfortable and positive atmosphere throughout the entire process. When it came to the installation, Kowalski HVAC's thoroughness blew me away. Their level of expertise was evident in every step of the job. From assessing my home's specific requirements to suggesting the best solutions, they left no stone unturned. It was clear that they wanted to ensure I got the most out of my new system, both in terms of performance and energy efficiency. What impressed me even more was how flawlessly they handled the relocation of the condenser and its electrical setup. Despite the added complexity, the team approached the task with confidence and skill. They coordinated everything with precision, resulting in a seamless integration of the new system. It was positioned and connected perfectly, guaranteeing optimal functionality and peace of mind. I can't stress enough how Kowalski HVAC's commitment to excellence shone through in every aspect of their work. They not only finished the job on time but also went the extra mile by cleaning up the work area afterwards. It's those little touches that make a big difference and show their dedication to ensuring a hassle-free experience for their customers. In conclusion, if you're looking for HVAC services that are not only top-notch but also delivered by a friendly and knowledgeable team, Kowalski HVAC is the way to go. Their exceptional service and attention to detail will leave you beyond satisfied. Whether it's a simple repair or a complete system replacement, trust Kowalski HVAC to exceed your expectations and provide you with a solution that will keep you comfortable for years to come. I wholeheartedly recommend them to anyone in need of HVAC services.
