Marion Heating Company

Providing Professional Heating & Furnace Solutions Since 1986

The homes that stay consistently warm through winter without generating outsized energy bills have something in common: a heating system that's been properly installed, correctly sized, and maintained regularly. 

At Master Plumbing, Heating & Cooling, helping Marion homeowners get that kind of performance out of their heating systems is what we do. We've been doing this since 1986, and we back every job with a satisfaction guarantee and warranties.

Getting started is straightforward. Call (319) 214-5064 or schedule your heating service online and let Master Plumbing, Heating & Cooling take it from there.

What You Can Expect from Our Heating Technicians 

  • Licensed, insured, and extensively trained. Every technician we send to your home meets a consistent standard of qualification and workmanship. Master Plumbing, Heating & Cooling is fully insured at the company level on every job.
  • A price before we start, not after. Once we've assessed the work, you receive a full upfront quote. No hourly billing accumulating while the job runs, no additions to the invoice once it's done.
  • Honest options. If a repair makes more sense than a replacement, we'll tell you that. If a system is approaching the end of its useful life and a further repair is only delaying the inevitable, we'll tell you that too. We work on all major brands, so our recommendations are never steered by brand preference.
  • A clean workspace throughout. Shoe covers go on at the door. Work areas are protected and cleaned up before we leave, and you'll get a call before we arrive so you can plan around us rather than the other way around.

Heating Emergencies: When to Call, What to Do While You Wait

Not every heating problem is an emergency, but some are, particularly in the middle of a Marion winter when temperatures can drop well below freezing overnight.

These situations warrant an immediate call:

  • Your heat goes out completely during freezing temperatures. A home without heat in below-freezing conditions can reach dangerous temperatures within hours, particularly for young children, elderly residents, and pets. Don't wait to see if it resolves itself.
  • You smell gas near your heating system. Leave the property immediately. Don't use any switches, open flames, or electrical devices. Once outside, call your gas provider first, then call us. This is not a situation to troubleshoot yourself.
  • Your carbon monoxide detector goes off. Leave immediately and call emergency services before calling anyone else. A carbon monoxide alarm near a gas furnace is a serious safety event.
  • You hear unusual sounds alongside a complete loss of heat. Banging, screeching, or grinding sounds combined with a system that stops producing heat can indicate a mechanical failure that needs immediate attention.

What to do while you wait for our technician:

If your heat is out but the situation is safe, keep heat loss to a minimum by closing off rooms you aren't using, keeping doors closed, and using extra blankets or a portable space heater in the room where your household is gathered. If you have a smart thermostat, leave it set to the target temperature so the system attempts to run when it can. Don't attempt to reset or manually override a system that has shut itself down due to a fault, as that shutoff is often a safety mechanism.

Emergency service is available 7 days a week. When you call (319) 214-5064, let us know the full situation and we'll prioritize accordingly.

  • Respectful & Tidy

    Our pros treat your home like their own, wearing shoe covers and leaving every work area spotless.

    Recognized 5 times by Angie's List for outstanding service, we go above and beyond to deliver exceptional results every time.

    Very happy with my new water heater and installation!!

    Lisa K.
    Very personable and I highly recommend him for any plumbing needs you may have.
    “Great experience with John. He is very knowledgeable and gets the work completed in a timely manner. He discussed everything he would be doing beforehand and told us the cost. When he was done, there was no up charging. The cost was exactly what he said it would be.”
    Elizabeth D.
    Appreciate the professional service!
    “John from Master Plumbing replaced my water heater after my old one failed. Despite it being after 4 pm, he was able to quickly pick up a replacement unit and install it the same evening, staying late to complete the task. He also went above and beyond to clean up the area around the old water heater, as well as my driveway after some of the water from the old water heater leaked out.”
    Ricky K.
    I will definitely recommend this company!
    “We had a water softener installed. I called Master Plumbing, Heating, and Cooling at about 8AM and we had a water softener installed by 12:15. Bill was our service technician. He was so very polite and respectful of our home! ( He wore shoe coverings) Bill explained everything extremely well. We bought their Green Club Membership, for a few dollars more, which will cover plumbing, heating, and cooling. Our systems are well over 25 years old, so over the long run this membership will save us a lot, Thank you Bill and Master Plumbing, Heating & Cooling.”

    I felt every detail was taken care of when they went out the door.
    “Matt and Sean came to do my fall furnace check this afternoon and I want to say I was very pleased. They checked the airflow that I never had done before, cleaned the drain that was covered with corrosion materials, and replaced the humidifier filter with a fresh one I had. I felt every detail was taken care of when they went out the door.”
    Phyliss K.

    “I called in the AM regarding our central air not working and spoke with Taylor who was so friendly and let me know they had an appointment in the afternoon. Maddie then kept in contact with me as to when Madison & Jordan would arrive. Madison and Jordan were very friendly and got to work right away and had the unit working quickly. Everything went smoothly and I cant say enough about every person I was in contact with. Such a great experience! Thank you all so much!”
    Denise E.
