I recently had Winter Brothers install a new furnace and air conditioning system in my home, and I couldn't be happier with the experience. Since the install, my home has been much more comfortable, and I’ve noticed a difference in energy efficiency. From start to finish, their team was professional, knowledgeable, and efficient. Thank you!

I’m a first time home owner, and Jason has helped me with multiple HVAC needs. A year ago he installed a new furnace for me. This year he helped me through a water damage crisis by moving my entire furnace and water heater, reinstalling it, and making it fully up to code. I could not imagine getting through that crisis without his help, hard work, wisdom, and kindness. He is also affordable and trustworthy.

Can’t recommend Winter Brothers enough. They showed up on time and even wore those goofy shoe protectors. They removed our old furnace and installed a new one all before noon. I had planned to be home all day but because they finished early I was able to get a quick hike in with my dog.

Jason is knowledgeable, honest, has good integrity, and is an efficient worker. He even solved a problem in our kitchen while he was replacing our furnace. Very helpful and thorough. He felt more trustworthy than HVAC techs we have worked with in the past.

Frequently asked questions

How often should I service my HVAC system?

To keep your heating and cooling system running efficiently, we recommend servicing your HVAC unit at least once a year—ideally before summer for AC and before winter for heating. Regular maintenance helps prevent costly breakdowns, improves efficiency, and extends the lifespan of your system.

Why is my HVAC system running but not heating or cooling properly?

If your system is running but not keeping your home comfortable, it could be due to a dirty air filter, refrigerant leak, thermostat issue, or blocked vents. Try checking and replacing the air filter first. If the problem persists, it’s best to schedule a professional inspection to diagnose and fix the issue.

How do I know if I need a new HVAC system?

If your system is over 15 years old, frequently needs repairs, struggles to maintain temperature, or causes high energy bills, it may be time for a replacement. A new, energy-efficient system can lower your utility costs and keep your home more comfortable year-round. Our team can assess your system and recommend the best option for your needs.
