Total Home Comfort With HVAC System Upgrades
Sometimes, an older HVAC system can no longer meet the demands of your home, leading to frequent repairs and inefficient operation. Zenner & Ritter is here to guide you through the process of upgrading or replacing your heating and cooling systems. We provide professional advice on the latest heating and air conditioning technologies and help you select the best system for your home and budget.
Your installation will be set up for maximum efficiency and performance. With our expertise, upgrading your heating or air conditioning system can be a smooth and stress-free process, providing you with a more comfortable and energy-efficient home for years to come.
HVAC Repair That Gets It Right The First Time
Heating and cooling problems rarely come with much warning. One day, the system seems fine, and the next, you’re dealing with weak airflow, strange noises, or a furnace that won’t turn on. That’s where our HVAC services can help. We troubleshoot furnaces, modern heat pumps, and central air conditioning systems, always taking the time to identify the root cause of the issue.
Buffalo homeowners often tell us they appreciate that we check the full system instead of stopping at the obvious repair. For instance, if your furnace needs a part replaced, we’ll also check the ductwork for leaks, inspect the thermostat calibration, and make sure airflow is balanced. This way, you don’t have a new part installed while hidden problems continue to strain the system.
Breathe Easy With Better Indoor Air Quality
At Zenner & Ritter, we understand the importance of clean air, and we offer solutions to improve your home's indoor environment. Our indoor air quality services include air duct cleaning, the installation of air cleaners and UV lights, and repairs to guarantee your home is free of air pollutants and allergens.
Our advanced air quality solutions can dramatically reduce dust, pollen, pet dander, and other airborne irritants. You can count on us to provide the best possible solutions to keep your indoor air quality at optimal levels for you and your family.

Quality Service. Quality Products.

Expert Plumbing Installations
Plumbing equipment should be installed with precision, because small mistakes can lead to substantial problems over time. That’s why homeowners trust us for professional plumbing installations across Buffalo. We take on plumbing services that range in scale. This means that our team can install a new water heater in your home or even outfit an entire bathroom during a renovation.
Our team installs both standard and tankless water heaters, working with reputable brands such as Bradford White, AO Smith, and Navien. In basements, we handle sump pump installations that protect homes from water damage during heavy storms. The work we do is designed to last, so families don’t have to deal with constant repairs or replacements.
Plumbing Repair That Lasts
Plumbing problems tend to snowball. A dripping faucet adds up to gallons of wasted water, and a small drain clog often grows until nothing moves at all. Our plumbers come prepared with professional-grade equipment so that we can deliver a solution that doesn’t just mask the problem.
We repair everyday issues like toilet leaks, shower blockages, and sump pump failures. Every repair ends with a clear explanation of what caused the issue and how to avoid it in the future. For many homeowners, that part matters just as much as the repair itself.
Reliable Generators to Power Your Peace of Mind
In Buffalo, where the weather can be unpredictable, having a reliable generator can be a lifesaver. We offer generator installation and maintenance services so that you always have power. Our generators are designed to provide a seamless transition during power outages, keeping your essential appliances, heating systems, and air conditioners running without interruption.
Our team will help you choose the right generator for your needs and provide professional installation and regular maintenance. With a reliable generator from Zenner & Ritter, you can have peace of mind knowing that your home will remain functional, even during the most severe weather events.

Safe and Skilled Generator Repair
A power outage in Buffalo can happen without warning, and without backup power, daily life comes to a sudden stop. Refrigerators lose electricity, basements risk flooding if sump pumps shut off, and heating systems can’t operate. That’s why so many families invest in standby generators, and why keeping them in working condition is critical.
Our technicians handle generator repair and maintenance with expertise on leading brands like Generac and Briggs & Stratton. Common issues include transfer switch failures, worn electrical components, and engines that won’t start. We perform full inspections, address the problem directly, and test everything so you know your system will hold up during the next outage. Buffalo weather can change on a dime, but our generator services give you steady backup power you can count on.
