How Do I Know If I Need A New Furnace? Helpful Guide

Signs that indicate you might need a new furnace

A furnace is a key home appliance that helps keep us warm in the wintertime. Still, like all other equipment, it has a life expectancy and, eventually, needs to be replaced. Here are some signs that may indicate your furnace needs to be replaced:

  • Age: A furnace usually lasts 15-20 years. If it’s over 20 years old, it may be time to get a new one.
  • Rise in energy bills: If you see a big increase in your monthly energy bills with no obvious reason or change in usage habits, it could be a problem with your heating system.
  • Repeated repairs: If you’re often getting repairs or spending money to fix issues with your furnace, it could be time for a new unit.
  • Poor air quality & strange noises: Old furnaces can struggle with air filtering and circulation, leading to poor air quality. Sounds like rattling, popping, or banging mean there are mechanical issues, which could require pricey repairs.
  • Carbon monoxide leaks: Carbon monoxide is an invisible gas created by the combustion process in gas furnaces. If the heat exchanger has cracks, this poisonous gas can escape into your home.

It’s important to keep an eye on these warning signs to avoid any troubles in the cold winter season. Also, regular maintenance of your HVAC system can extend its lifespan and help you avoid costly repairs.

My cousin Kenyon went through something similar last year. His 15-year-old gas furnace started causing trouble and high heating bills. He hired a local HVAC contractor who checked his unit and suggested buying a new one due to its low AFUE rating (energy efficiency indicator). Kenyon also joined Liberty Home Guard’s home warranty program to protect himself against future heating-related issues. He spent around $3,000 on a new furnace, but now he has lower energy bills and peace of mind.

Like working out, regular furnace maintenance isn’t fun, but it’s necessary for a healthy and long life.

The importance of regular maintenance

It’s key to look after your furnace. Poor care could cause health problems, and costly repairs or replacements. To keep it running well and save money, get regular cleanings, filter changes, and tune-ups from an expert HVAC contractor. Signs like odd noises, frequent repairs, or higher bills show it needs help. Ignoring regular maintenance can lead to more expense on heating or a broken furnace when you least expect it. Take care of your furnace and relax knowing it’s safe and efficient.

Time for a replacement? Think about cost, energy efficiency, and lifespan – that’ll make the process simpler.

Factors to consider when replacing your furnace

Replacing your furnace is a decision that needs careful thought. Various factors should be weighed prior to turning to the pros and buying a new furnace:

  • Age– If the furnace is older than 15 years, it’s time to think of replacing it. Even if you’ve been diligent with maintenance, signs of aging will show.
  • Repairs– If repair bills start rising, it’s better to buy a new one than keep paying for repairs.
  • Utility Bills– If heating bills increase even with regular use and maintenance, it could mean the furnace is running inefficiently.
  • Noises– Unusual noises from the furnace usually indicate mechanical issues or wear and tear, signaling to replace the unit.
  • Air Quality– Bad air quality in your home may be because of problems with the heating equipment, particularly an oil or gas furnace.

Each situation is unique, so the above factors shouldn’t be taken as a must. Plus, the professional assessment would be best to know if a replacement is suitable.

To avert future hassles with replacement costs or safety hazards from carbon monoxide leaks and malfunctions, consider the following:

  • Maintenance: Get professional servicing at least once a year or depending on the frequency of use.
  • Know Your Type: Understand the fuel source you use for the HVAC system. Is it gas? Propane? Oil? Knowing this will help when talking to contractors.
  • Fuel Efficiency: When replacing appliances, get ones certified by ENERGY STAR with high AFUE ratings.
  • Manual: Keep a copy of the operation manual, in case of trouble or abnormalities.
  • Warranty: Having a home warranty can protect you from unexpected repair, replacement, or maintenance costs. Look into providers like Liberty Home Guard.

Remember these factors and tips to ponder over furnace replacement costs and other HVAC matters. HVAC contractors can be like superheroes; choose the right one and they can rescue you from furnace disasters.

Choosing the right HVAC contractor

Search for a provider with experience in the industry. They should be able to look at all aspects of your system and recommend options that save money and improve efficiency.

Look for traits such as responsiveness, promptness, and advice-giving. Reading reviews can give insight too.

If unsure who to call or hesitant about spending money on a new AC or heating unit, find a home warranty company like Liberty Home Guard. They offer services for the damage that normal homeowner contracts do not cover.

Choosing an HVAC pro gives peace of mind that everything related to your home’s utilities is taken care of. Act now before winter comes!

Before replacing a furnace, consider the age of the home, energy efficiency, and cost of repairs vs. the new unit.

Other considerations before replacing your furnace

Replacing a furnace is a big decision. Consider several factors before taking this step. Check if you’ve changed your home’s insulation or added new windows. This may affect the furnace size and energy needs.

Think about the cost of maintenance and repairs compared to the price of a new furnace. Don’t keep spending money on an old system that will soon need replacement.

Your comfort level also matters. If some rooms are colder than others, or you experience cold air drafts, it’s time for a replacement. An old furnace consumes more fuel, increasing your utility bills and wearing out other appliances. Monitor your bills for any excessive increase.

Air quality and health risks are also important. As furnaces age, they produce strange noises and emit carbon monoxide gases. These can cause severe health problems if undetected. Watch out for warning signs like sudden repair bills or heating inefficiencies.

Think about these signs before it’s too late: time for a furnace replacement!


When it comes to having a comfortable home, heating systems are important. If your furnace isn’t working as it should, signs like old age, repairs, noise, rising energy bills, drafty rooms, and poor air quality may show. If you see any of these, it’s time for a replacement.

Get a professional HVAC contractor to evaluate if you’re unsure. Maintenance services and filter changes over time also help prolong the lifespan. Most furnaces last 15-20 years. Without proper attention, life could be shorter.

Before investing in something expensive like a furnace, get a home warranty. It can help cover any unexpected costs related to repair or replacement due to normal use.
