Smarter Heat Starts Here

Heating your home should not mean overworking your system or overpaying on energy bills. The right setup makes all the difference. From boilers and furnaces to full HVAC systems, each installation is tailored to your home so heat is delivered efficiently and evenly. When everything is sized and configured correctly, your system uses less energy to maintain comfort. That means fewer fluctuations, less strain on equipment, and a home that stays warm without unnecessary waste or rising utility costs. It’s a smarter approach that supports both your comfort and your long-term efficiency.

Really excellent experience with kenco! Communication was great and response times were quick! Hayden was very helpful answering my all my plumbing questions and was transparent as to the work he was doing. I would trust them for all plumbing work in the future. Highly recommend!!

We had a relatively simple job replacing a spigot for a hose, but even though it was a small job I felt that I got superior service throughout. I called on Thursday and got an appt for Monday. Hayden let me know mid-afternoon on Monday that he was running late due to complications on the prior job, and by the time he was finished it was pretty late. He was still willing to come, but I asked if we could reschedule and he was fine with that. The office called me first thing Tuesday morning to reschedule and Hayden and Will were at my house before 11:00. They were very pleasant to work with and did a great job! I highly recommend.

I was struggling to find a plumber who would break through my slab and find the leak in my kitchen. I stumbled upon Kenco, while looking for someone local, and couldn’t have been happier. Paige was great to speak with, and Leon & Dan came out within twenty minutes to take a look. Leon was more than prepared and immediately took on the project, successfully identifying where the leak was and fixing it that evening. I couldn’t recommend them enough!

FAQs

Answers You Can Rely On

See All FAQs

How do I know if I need a new heating system or just a repair?

If your system is frequently breaking down, struggling to keep up, or causing higher energy bills, replacement may be the better long-term option. For smaller issues or newer systems, a repair can often restore proper performance.

What types of heating systems do you install?

We install boilers, furnaces, and complete HVAC heating systems. Each option is selected based on your home’s layout, size, and overall comfort goals.

How often should my heating system be serviced?

Heating systems should typically be serviced once a year to maintain efficiency and catch potential issues early. Routine maintenance helps extend the life of your equipment and reduce the risk of breakdowns.

Can a more efficient system actually lower my energy costs?

Yes, modern systems are designed to use less energy while maintaining consistent temperatures. With proper installation, that efficiency can lead to noticeable savings
