Before You Call, Try These Quick Fixes!

Check your Thermostat

Your thermostat will protect your HVAC system by causing it to delay when switching between heat and cooling mode. You may expect to be able to just increase the temperature a few degrees and a warm blast will immediately come from your vents, but you may not realize that the “lockout” from your thermostat will prevent that from happening. It’s usually only a 5 minute delay, but make sure your thermostat is set to heating mode and you have the set temperature above the indoor temperature a couple degrees. Then, wait a little while. If “heating” is blinking, it normally means your HVAC system is in the delay period. If it goes solid and you still don’t have any heat, give us a call.

Check the Gas

Running out of gas or not having the gas turned on happens more times than you’d think, especially when heating your home with LP (liquid propane). If you have other gas appliances in your home such as gas logs or a gas stove, make sure they are working properly. If they are working, then you’ll probably have to give us a call, but if they are also off, it might be a gas supply issue. If that’s the case, you’ll want to turn off all the appliances and make sure all gas control valves are set to off, and call your gas company for help.

Check the Air Filters

Air flow is very important to any central HVAC system. Bad things happen when airflow is reduced below the design specifications. On a furnace, three things in particular can happen when your filters get so clogged they choke your system’s air flow:

  1. (1) Increased internal temperatures. When airflow is reduced, the internal temperatures in the furnace increase, sometimes to the point that an internal safety limit switch is tripped. When this happens, your furnace will shut down and then “short cycle.” After it cools enough, it will turn back on, heat up too much, cut off, wait to cool down, and then startup again. This is, of course, not an efficient or reliable operating cycle for your furnace.
  2. (2) Heat exchanger problems. Overheating the heat exchanger can reduce it’s life. Heat exchangers are designed for a specific temperature range that should not be exceeded.
  3. (3) Shortened blower life. The blower moves the warm air through your home. Reduced airflow creates additional blower load that will increase your power usage and reduce the life of your blower.

Common Furnace & Heating System Repairs

What does it do?

The furnace heat exchanger is used to transfer the heat from the flames into the building air flow. The heat exchanger is the primary component of a gas-fired furnace.

Why did it fail?

Heat exchangers expand and contract every time they are heated up. Over time they will crack and start leaking carbon monoxide into the building air flow.

Will it fail again?

Heat exchangers are designed to last 15 years with proper usage and maintenance. An over-fired furnace can shorten the lifetime of the heat exchanger.

What does it do?

The blower motor is the power behind the blower wheel that moves the air throughout the house. The blower motor allows for a comfortable living environment.

Why did it fail?

Over time, blower motors will fail as the bearings become worn out. They can also develop internal shorts over the lifetime of the unit.

Will it fail again?

Fan motors commonly last 10 to 15 years with proper maintenance and normal usage. Older motors have to be oiled yearly.

What does it do?

The safety pressure switch is used to sense the pressure build up inside the exhaust flue pipe. The safety pressure switch is to ensure the furnace has a clear flue pipe before the flame is ignited.

Why did it fail?

Safety pressure switches commonly fail when they become flooded due to lack of or poor maintenance leading to the drain line backing up. They can also fail with age.

Will it fail again?

With proper usage and maintenance, the safety pressure switch should last the lifetime of the unit, but they commonly start to become weak after 10 years age.

What does it do?

Wiring is a copper or aluminum conductor that allows electricity to run from the main house panel to the equipment. The wire is also used to move electricity around inside the unit to various parts for proper operation.

Why did it fail?

Wire fails when the insulation around the conductor wears out and cracks, causing a short. Wire fails can be caused by age or the unit drawing too much power. Shorts can be a fire hazard as well.

Will it fail again?

Wire normally lasts the lifetime of the unit, with proper maintenance and usage. Wiring will fail again if the damage is caused by overpowering and the problem is not corrected.

What does it do?

The thermostat is the main control for the unit. It senses the air in the building and turns the heat or the A/C on to keep the air at a comfortable temperature inside the building.

Why did it fail?

Thermostats commonly fail with age or from power surges. Older thermostats will need their batteries replaced regularly to keep working.

Will it fail again?

Thermostats are designed to last about 10 years before the circuitry begins to go bad.

What does it do?

Ignitor probes are used to ignite the gas in the furnace. When ignitor probes are turned on, they increase in temperature until they reach a temperature that causes ignition.

Why did it fail?

Ignitors primarily fail due to age. An ignitor works very much like a light bulb and will burn out over time. Power surges can also destroy an ignitor.

Will it fail again?

Ignitors are designed to last about 10 years with proper usage and maintenance.

The Comfort Monster Heating System Repair Experience

1. Request a Diagnostic

Contact us online, text us, or call us at 919-MONSTER to request an appointment when we can come to your home and diagnose your issue. You will speak with a friendly Customer Care Rep (CCR) to find a time that works within your busy schedule.

2. Receive an Arrival Call and Text

Your professionally-trained technician will call you when they are on their way to your home, so you know exactly when they will be arriving. In addition, you will get a text message and/or email (depending on your preferences) with a recent photo of your technician, so you can see who to expect, and a link to our tracker where you can view their route as they drive to your home.

3. Learn about options from a trustworthy technician

Once your technician arrives, they will examine your system, talk to you about your comfort needs and create estimates for any work that might be needed to get your system going or recommended to keep it humming reliably. We provide lots of information, and we love to answer questions!

At Comfort Monster, your tech’s performance is based on how well they take care of you — and NEVER on selling you things you don’t need.

4. Choose the fix for your system and get scheduled

When your system can be fixed right on the spot, we can go ahead and do that as soon as you’ve made a decision about what you want to do.

But your system is made up of many parts that are unique to that specific make and model, so we may need to order the correct part and schedule a time to come back and fix it as soon as we can get our hands on the part. In some cases we can put a temporary fix in place to keep you comfortable while waiting, and in other cases we might offer to lend you space heaters or window air conditioners (based on availability, MonsterCare members get priority for those).

5. Give us feedback

Finally, we’ll ask for your feedback on how we did so we can make sure you were 100% satisfied. And if you’re not? Let us know, we’ll make things right!
