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 & Air, 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 & Air 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 & Air 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.

How We Determine the Right Heating System for Your Home
Not every home needs the same solution, and recommending one without properly assessing the home first is one of the more common ways heating installations go wrong. Here's how we approach it:
We start with the home, not the equipment. Before we talk about brands, models, or price points, we look at the home itself. Square footage, ceiling height, insulation levels, window placement, and how the existing ductwork is configured all affect how a heating system needs to be sized and set up to perform properly.
We account for how the home is actually used. A household that keeps consistent temperatures throughout the day has different heating demands than one where the home sits empty for most of it. Zoning, programmable controls, and system type all factor into what makes the most practical sense for how your family lives in the space.
We consider the existing infrastructure. In older homes, the ductwork, gas lines, and electrical systems that a new heating unit connects to may need attention before or during installation. We assess what's already there and factor that into our recommendations so there are no surprises once the job is underway.
We look at efficiency relative to the home's characteristics. A high-efficiency system delivers its rated performance only when it's correctly matched to the space it's heating. We install and service Lennox heating systems, which consistently rank among the most energy-efficient options available, alongside all other major brands.
We give you options, not a single take-it-or-leave-it recommendation. Once we've assessed the home, we'll present the options that make sense for your situation, from straightforward replacements that match your existing setup to upgrades that deliver meaningful long-term improvements in efficiency and comfort. We explain what each one involves and what it realistically means for your home and your energy bills, and we let you decide.

Frequently Asked Questions
How often should a furnace be serviced?
Once a year is the standard recommendation, and early fall is the most practical time to schedule it in Marion. Getting the system looked at before the heating season begins means any issues are addressed before you're dependent on the system through the coldest months. It also means you're not competing with emergency calls mid-winter.
My heating system is working, but some rooms are much colder than others. What's causing that?
In our experience, uneven heating is typically caused by an improperly sized system, a struggling air handler, or spaces that would be better served by a ductless solution. Our technician can assess the problem and give you a clear picture of what's behind.
Is a gas log fireplace a practical heating option or mainly decorative?
It depends on the unit. Vented gas log fireplaces are primarily aesthetic and contribute relatively little usable heat to a space. Ventless models produce more heat but come with their own considerations around air quality and where they can be safely installed. If you're considering a gas log fireplace as a supplemental heating source for a specific room, it's worth having a conversation about which type makes sense for your home.
Is there a fee for the initial visit?
There is a diagnostic fee for the initial visit. You'll know what that costs before we come out, and once we've assessed the system, you'll receive a complete quote before any work begins.
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.
Our pros treat your home like their own, wearing shoe covers and leaving every work area spotless.

Would highly recommend!
“Bill M was my service technician. Very thorough and explained everything so I understood. Gave tips on future maintenance and did a great job of getting the new water heater installed and the old removed in a very timely manner as well as any cleanup.”
Becky W.
Would definitely recommend him and Master Plumbing.
“John came out to do my annual plumbing inspection; caught and fixed a few things (had pictures of discrepancies), cleaned out my tankless hot water heater at no charge.”
Eric F.
I highly recommend!
“I am happy to share that the team at Master Plumbing, Heating & Cooling responded quickly to repair my furnace. The service technicians (Brett & Jordie) were friendly, informative, and fast. They left the furnace room cleaner than they found it.”
Donald B.
I would shout from the mountaintop my 100% recommendation for Master Plumbing!
“John was amazing!! He was courteous, kind, prompt, respectful and very knowledgeable! If I could give him 10 stars or more, I definitely would!! He took care of our "emergency" , took time to explain everything to us and even confirmed for us and appliance maintenance provider to contact. I would shout from the mountaintop my 100% recommendation for Master Plumbing and definitely for John!!”
Sue P.
I would 100% recommend Master Plumbing Heating and Cooling
“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.
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.
My entire experience with Master Heating, Plumbing, and Cooling was a 10 out of 10.
“Bill M was my service tech, I don’t know if he was a plumber but he certainly installed my sump pump with absolutely no problem. He explained to me in the beginning that my sump pump “could fail” but did not try and pressure sales me into anything. What he said made me comfortable in his knowledge and I trust him. I did not get the idea that he was just trying to make the company money by upselling to me either. So exceptional work from Bill M. I’d also like to say I had a couple interactions with the office staff as well. Taylor and Allie are top notch as well. My entire experience with Master Heating, Plumbing, and Cooling was a 10 out of 10. I will continue to use them in all my heating, plumbing and cooling issues that arise.”
