"I had questions about the furnace (we recently bought the house) and the tech took the time to carefully answer them.

He also quoted me a couple of things but he said they were optional and not necessary. I loved that he didn't try to use pressure tactics to upsell me when my system does not need them.

And they were competitively priced.

I will definitely hire them again in the spring for the A/C tune-up."

- Glenn S., Eagan

"My A/C went out on the hottest weekend of the year and I know Bob Boldt HVAC was busy with a lot of customer calls.

When Sam came out, not only did he fix the issue but he took the time to explain everything to me. He also made recommendations on settings and got my A/C working great!

He was so nice and professional!

Bob Boldt HVAC will be my first call every time!"

- Sunny S., Eagan

"I have worked with Bob Boldt for a little over a year now, we had them install a new boiler and have done a couple inspections through them.

They are reasonably priced and professional.

I would highly recommend this business."

Common Heating Questions

How Do I Know If My Furnace Needs Repair or Maintenance?
If your furnace is 12-15+ years old, you haven't touched it in 3+ years or your home isn't staying consistently warm throughout every room - it may be time to have it looked at!

Do You Offer Emergency Furnace Repair in Burnsville and Nearby Areas?
Yes, we do offer emergency services, but also believe that transparency is vital. Which is why most of the time, bundling up and using a space heater or stove can keep you warm enough until we can get out there the next day. This reduces those hefty emergency fees and keeps you comfortable.

Is A Furnace Tune-Up Really Needed?
If you like staying warm, safe and keeping your money - then yes, furnace tune-ups are really needed. They help prevent breakdowns, identify hazards and issues to improve your safety and your system's efficiency while saving you money in the long run!

When Should I Replace My Furnace Filter?
Furnace filters need replacement based on the size of the filter and your home's environment. If you have an inch filter, replace them monthly. If you have a four inch filter you can replace your furnace filter every six (6) months. However, if you have pets, allergies or those with breathing problems - check your filter every month!

Common Cooling Questions

How Do I Know If My Air Conditioner Needs Repair or Maintenance?
If your AC unit is 12-15+ years old, sinking into the ground or you notice higher energy bills - it's probably time for a checkup.

What Are Some Signs My AC Is Low On Refrigerant or Needs A Recharge?
If your air conditioning unit hisses at you, you notice puddles or ice forming around your unit or your AC is blowing hot air, it's time for a recharge!

What Do To If My AC Unit's Freon Is Not Made Anymore?
As environmental and manufacturing processes change, certain air conditioning unit's freon will be discountinued. Contact us to see if we have your AC unit's refrigerant in stock.

Why Does My AC Keep Running Constantly?
With extreme heat it is expected that your air conditioner will run more frequently, but if you notice it not turning off at all or it constantly filters between running and off, bigger issues are at play. Dirty filters, low refrigerant, duct issues, inadequately sized units or internal damages may be at fault. Call for an appointment.

Why Is My AC Blowing Hot Air?
If your air conditioner is blowing hot air it could mean that your system is clogged, without refrigerant, have a damaged compressor or that you have thermostat problems.

System Safety & Comfort Questions

Do You Test For Carbon Monoxide?
Yes, we always test for carbon monoxide upon entering a home and report all of our findings to you with our recommendations to ensure a safe and comfortable home.

Why Is Your Carbon Monoxide Reading So Much Higher Than Others?
We test for carbon monoxide at various speeds and locations throughout your home. For instance, you might have a low reading when your furnace is on high speed, but then jump to dangerous levels when the fan speed is lowered. Since your system isn't constantly running on high, we test for all variants to ensure your entire home is safe.

Why Am I Constantly Getting Sick?
If you are getting sick often, your heating and cooling system might be to blame! If your air quality is impaired or there is low humidity in your home, you will get sick more often due to heavy pollutants circulating and dry air. Dirty systems push out microscopic soot and debris which is a leading cause for irritated throats, coughs and common cold-like symptoms.

High carbon monoxide levels can also make you feel nausea, tired or have frequent headaches. Those with allergies, breathing conditions, pets and children or the elderly are more susceptible to heath issues and you should schedule an inspection immediately.
