Furnace Repair Q&A

Published by Webmaster

Our winters in Crystal Lake, IL put our furnaces through a lot of use. Many homeowners are familiar with basic maintenance for their AC but, not so familiar with furnace repair and maintenance. We’re going to address some of the most common questions regarding furnace repair and furnace problems we commonly see and their possible solutions. If you still don’t find the answers you’re looking for, call Weatherwise, IL at 815.477.7766.

While every system is different, here are some common furnace questions and answers:

Q: How do I maintain my furnace?

A: Always follow the guidelines and recommendations found in your manufacturer’s manual. Here are some general suggestions: Clear out any clogs or blockages in the filters and drains monthly. Always have a carbon monoxide detector in your home to ensure safety and have a professional HVAC technician complete an annual maintenance check-up once a year.

Q: What’s included in a furnace check-up/tune-up?

A: Our certified technicians will complete a list of checks to ensure your furnace is running smoothly and we guarantee it. The Weatherwise furnace tune-up checklist includes:

  • Comprehensive adjustments
  • 100% Full Safety Inspection
  • Air filter inspection
  • Thermostat check
  • Air vent overview
  • Pilot evaluation
  • Gas evaluation

Q: How do I change a dirty furnace filter?

A: An old filter can drive up your energy bill and cause a host of other issues. Remember to change your filter often; length varies by your unit.

Q: My thermostat isn’t working. What do I do?

A: Try changing the batteries, rebooting, or turning the breaker switch off for 30 seconds before turning it back on.

Q: Why does my furnace keep tripping the breaker?

A: If your furnace keeps tripping the breaker or blowing the fuse when the heat kicks in, it’s most likely an electrical issue. To keep you and your family safe, please call professionals to take a look. You can reach us at 815-477-7766 for heating service in Crystal Lake, Illinois, and beyond.

I've been using WeatherWise for years and always happy with the service.

They are always on time and best of all, reasonably priced. It's hard to find a company in that industry that you can trust. They have been there when I needed them. I trust WeatherWise and have recommended their service for my neighbors who are also very happy. I recently had them install a new furnace and air conditioner and was surprised that both were installed in less than a day. Keep up the good work!

I had weather wise come out to my home to put on a new humidifier.

They completed the job quickly, professionally, and explained how everything worked to me and my husband. When the crew was finished, they left our basement neat, clean and tidy. For the price, you really can't beat their great service!

Weatherwise is amazing.

I can tell you that these guys really know what they are doing, they are priced very fair, and treat you like friends and family. Of all the service companies I have dealt with in my time they are by far the best. Frank, on behalf of my family and my self we thank you from the bottom of our hearts for your service. A new furnace 2 days before -25 degree temps is a huge relief. Thanks again and we will see you next fall for service.
