Furnace problems? Check these 5 things first

It can be frustrating when your furnace stops working properly in the dead of winter. And while we’re always happy to send a technician to your home, here are five things any homeowner can check before calling in a professional.

The thermostat

Is it set to heat? It’s surprisingly easy to forget to switch your thermostat from ‘cool’ to ‘heat’ when the cold weather hits. So double-check, just to be sure.

The furnace switch

Is it on? Your furnace has a safety feature called the disconnect switch, usually located on the side of your equipment or nearby on the wall. Sometimes it gets flipped by accident – if an item is leaned up against it, or if someone turns it off and forgets to turn it back on. If your furnace doesn’t have power, check the switch.

The circuit breaker

Is it set to ‘on’? Your home’s breaker panel contains a circuit for your furnace. If it has shut off, your home won’t have heat. Check your breaker panel and make sure the breaker is in the right position.

The furnace vents

Are they clear? Your furnace may not work properly if the air vents that lead from the outside of your home are blocked. Snow, slush, debris, or small animals nesting inside can all cause a problem. A technician from Reliance™ can do a thorough vent inspection, but it doesn’t hurt to take a quick look yourself.

The furnace filter

Is it old? Your furnace filter should be changed every three months or according to the manufacturer’s recommendations. Filters become dirty over time, and may cause your furnace to under perform. If you notice a change in your home heating, a new furnace filter may be the only fix you need.

At Reliance™, we’re here to help. Here are some common home heating questions.

How does a furnace produce heat?

A furnace ignites fuel in a combustion chamber to up heat exchanger coils. Air is drawn across the coils and warmed. Then, this warm air is distributed throughout your home through the ductwork and heating vents.

What is a boiler?

A boiler is another home heating system, more often found in older homes. Instead of heating and distributing air, a boiler system heats a liquid – usually water or glycol – which is pumped to radiators located throughout the home.

What can I do to reduce my energy bills?

If you want to save on your energy bills the best place to start is by conserving energy. You can hire a professional to conduct an energy audit to identify opportunities to save energy, and there may be grants available to help you cover the cost. You can also follow these simple suggestions:

  • When it’s time to upgrade your furnace, chose a modern high efficiency condensing furnace. It will use less energy to heat your space.
  • A programmable thermostat can help you monitor and take control of your energy use, and may be a good investment if you are looking to reduce your energy consumption.
  • Make sure your windows are properly sealed, or replace them with new ones.
  • Fill any cracks in your exterior walls.
  • Consider adding more insulation to your attic and basement.

Is a high efficiency furnace worth the investment?

If you want to conserve energy and save money, investing in a modern high efficiency furnace may make sense. Today’s energy efficient furnaces have an AFUE rating between 92% – 98%, a significant increase over older models. When used alongside smart technology, you’ll be able to maximize your energy efficiency and control your energy consumption which may result in lower home heating bills.

What does a whole home humidifier do?

A whole home humidifier keeps the humidity level in your home stable, regardless of the weather outside. This creates healthier air throughout your home and may help reduce your overall energy consumption.

What can I do to maintain my furnace?

Your furnace should only be opened and repaired by a trained furnace technician. However, homeowners can do a few simple things to help keep their furnace operating properly:

  • Change the furnace filter. Most filters need to be changed every three months, or according to the recommendations of your equipment manufacturer.
  • Clean your heating grills, radiators, and intake vents. Dust and debris may cause your home heating system to underperform.
  • Keep your exterior exhaust vents clear. Snow, slush, and ice can easily build up during the winter months.
  • Keep the space around your furnace or boiler clutter-free.
  • Have your furnace or boiler inspected and serviced every year.

When do I need an immediate furnace inspection?

It’s time to call a professional if your furnace is leaking water or making strange noises, if your home heating is inconsistent or costs more than usual, or if you notice your house is dustier than normal.

Should I rent or buy my new furnace?

Your Reliance™ Home Heating Advisor can help you weigh the pros and cons of renting or buying your new furnace. But here are a few things to consider:

  • If you buy your furnace you will be responsible for all repairs and maintenance as soon as your warranty expires. A comprehensive Protection Plan can help you avoid unexpected repair costs. Buying a furnace is a large investment, but it may add value to your home.
  • If you rent your furnace you’ll pay one low monthly fee, and we’ll look after most repairs and maintenance.

Should I upgrade my AC when I get a new furnace?

It can make sense to upgrade your furnace and AC at the same time. Systems designed to work together are more energy efficient and could save you on your energy bills.
