What's included in maintenance
Repair
Signs you may need heating repair

Heating systems often show warning signs before they fail completely.

  • No heat or insufficient heat

  • Cold air blowing from vents

  • Unusual noises (banging, rattling, whistling)

  • Frequent cycling on and off

  • Rising energy bills without explanation

  • Uneven temperatures from room to room

Addressing problems early can prevent more serious damage.

Our repair process

When you call T M Johnson Bros, we focus on accuracy and transparency.

  • Thorough system inspection

  • Clear explanation of what's wrong

  • Honest recommendations - repair when possible, replace when necessary

  • Quality repairs using proven parts and techniques

Replace
When it's time for a new system

If your heating system is aging, inefficient or requiring frequent repairs, replacement may be the smarter long-term solution.

Modern heating systems are significantly more efficient and reliable than older units. We'll help you compare repair costs, efficiency improvements and long-term reliability so you can make an informed decision.

We help homeowners evaluate:

  • System age and condition

  • Repair history

  • Energy efficiency

  • Home size and layout

Our goal is to recommend a system that fits your home and your budget.

We offer free quotes for replacement.

Frequently Asked Questions

For most homes, a heating system should be serviced once per year. Annual maintenance helps catch small issues early, improves efficiency, and reduces the chance of a breakdown. If your system is older, running constantly, or you've had repeated repairs, a proactive schedule matters even more. If you want us to handle reminders and timing automatically, our Maintenance Plan is built for that.

The most common causes are surprisingly simple: a clogged filter restricting air flow, a thermostat setting or battery issue, a tripped breaker, or a safety switch shutting the system down. 

  • Check the thermostat: Make sure it's set to "Heat", the temperature is above room temp and replace batteries if the screen is dim.

  • Check power: Confirm the furnace switch is on and your breaker hasn't tripped.

  • Check the filter: If it's dirty, replace it. Restricted airflow can shut systems down.

  • Check vents / exhaust: If your system has exterior venting, ensure snow or debris isn't blocking it.

If you still don't have heat; stop troubleshooting and call us to help. We'll diagnose the issue and get you back to safe, comfortable temperature. 

A repair often makes sense when the system is relatively new, the issue is isolated and performance has been stable. Replacement becomes more attractive when the system is older, repairs are frequent, efficiency has dropped or comfort problems are persistent (uneven heating, long runtimes, rising energy bills). The best next step is a diagnostic visit. We'll explain what's happening and give you a clear recommendation based on cost, safety and long-term value.

There isn't one perfect number, but most homeowners balance comfort and savings by setting a steady temperature when home and lowering it slightly when sleeping or away. If you're leaving for an extended trip, don't shut the heat off. Keeping the home warm enough helps reduce freeze risk and protects plumbing. If you have a smart thermostat, consistent scheduling can also reduce short cycling and improve comfort.

Heating Problems & Solutions

When your heat stops working, the most common cause is a failed component - such as an ignition switch, blower motor, thermostat issue, or a safety sensor shutting the system off. Modern furnaces are designed to shut down if something isn't operating safely, which means sometimes the system is protecting itself rather than "breaking" . A clogged filter or dirty  flame sensor can be enough to trigger a shutdown.

A furnace should not sound like a jet engine or a toolbox. Grinding, banging, squealing, whistling, or rattling are all warning signs. These noises often signal issues such as loose blower wheel, failing motor bearings, duct pressure problems or delayed ignition. If caught early, many of these problems can be repaired without major parts replacement. 

​

We will perform an inspection to pinpoint the source of the noise and check for additional wear or safety concerns. Once we understand what's happening you'll get clear repair options based on urgency and cost. Sometimes tightening a component or adjusting airflow solves the issue. 

If one room is warm and another feels like a meat locker, the issue is usually airflow. Common causes include blocked ducts, a failing bower motor, dirty filters, improper system sizing, or duct leaks in unconditioned spaces like attics or basements. A furnace can be running perfectly fine and still fail to push air evenly throughout the home. ​

​

We assess the entire system - not just the furnace - to determine what's restricting airflow or heat distribution. Sometimes it's as simple as adjusting dampers or sealing a duct leak. In other cases, the solution might be  zoning or balancing the system. Our goal is to help every room reach the temperature you set without wasting energy or money.

If your energy bill keeps climbing even though your thermostat habits haven't changed, your system may be running longer or working harder than it should. Dirty filters, clogged burners, failing components, or duct leakage can all force a furnace to run inefficiently. A drop in system efficiency doesn't typically happen overnight it builds over time. 

​

A tune-up and inspection can identify what's causing the energy loss. We'll test efficiency, clean components, and make sure everything is burning and venting correctly. If repairs are needed, we give you multiple options, along with transparent pricing. If you're considering replacement, we'll explain whether upgrading will actually save money long-term.
