LET'S TALK

Common Furnace Problems We Fix

If your furnace is acting up, you’re not alone. We commonly help homeowners with issues like:


  • Furnace won’t turn on
  • System runs but blows cold air
  • Heat isn’t keeping up or rooms are unevenly heated
  • Furnace turns on and off repeatedly (short cycling)
  • Unusual noises (rattling, squealing, booming, buzzing)
  • Burning or strange odors
  • Weak airflow from vents
  • Thermostat not responding or not holding temperature
  • Higher heating bills without a clear reason

If something seems “off,” it’s worth getting it checked early—small problems can turn into bigger repairs in the cold.

Real Reviews From Real Homeowners

In honor of Women's History Month Frank's put on an evening plumbing class for women which I attended with a friend. Abby, Mike and Frank were incredibly welcoming and generous with their time for this free event. Mike and Frank traded off during the presentation and their passion for their work was obvious. They let us ask as many questions as we wanted and provided thorough explanations of common household plumbing issues. Always make sure your sump pump is plugged in before you call a professional!

I especially appreciated that they were very clear that they would not be making any sales during or after the class. If you want to set up an appointment you have to call the next day. There was no pressure to buy anything, it was truly just a free service to better the community and that is hard to find these days.

"The whole team was so very helpful and made me feel comfortable..."

Was visiting family and a drain clogged up. I had to leave next day out of state and Franks plumbing (Kyle) came by. Kyle was so friendly, went above and beyond. Have had plumbers play tricks before and not with Frank's. Will be using them for life. The whole team was so very helpful and made me feel comfortable that I could trust them to work with my family member who was at the house.

"They were excellent and I will never go with any other company!"

Al and Dante were amazing! Very polite and professional. Al explained everything to both me and my husband so we could actually understand what is going on. Al said the sump pump looks good other than the roots that are growing inside. He told us exactly how to fix that problem. He was able to get the hot water tank lit again, but did honestly say it will most likely need to be replaced. Thank you for your great service!

"Both of these gentlemen had pure compassion for me as a customer."

I wanted to share my gratitude to Mike Russo (manager) for taking a lot of effort to keep me happy and take care of my sump pump issue quickly and for sending out one of his best techs (Seth) who was fantastic! Both of these gentlemen had pure compassion for me as a customer. A lot of places just want to fix it, get paid and leave. People who take the time to listen to the customer and talk/explain/etc. are what matters to us homeowners.

"...Diligent in explaining and showing what was going on...."

Tanis was prompt, professional, courteous, and solved our problem well. He was particularly diligent in explaining and showing what was going on and left the work area super clean. Great work!

"So beyond thankful for Mike, Abby, and Frank for their hospitality today during their class!"

I cannot begin to describe the amount of information they provided to us all... and the truly best part…the community they are building. I truly cannot wait to go to more classes in the future. Because of this class I know without a doubt who I will be calling for any plumbing needs moving forward. Thank you, Mike, Abby, and Frank!”

Furnace Repair FAQs

  • Why is my furnace blowing cold air?

    This can happen due to thermostat settings, airflow issues, or problems with how the system is operating. A diagnostic is the fastest way to identify the cause.

  • Why does my furnace keep turning off?

    Short cycling can be caused by several issues, including airflow restrictions or system control problems. We’ll test the system and explain what’s happening.

  • Is it normal to smell something when the heat turns on?

    A brief, mild odor can be normal at the start of the season. Strong or persistent odors should be checked.

  • How much does furnace repair cost?

    Cost depends on the cause of the issue and the parts required. We’ll diagnose first and explain options before work begins.

  • How often should a furnace be serviced?

    Most furnaces benefit from yearly maintenance, ideally before the heating season.

Prevent Winter Breakdowns with Heating Maintenance

A lot of mid-winter furnace failures start as small issues. Seasonal maintenance helps your system run more reliably and can reduce unexpected breakdowns when you need heat most.
