When Is It Time to Replace the Gas Furnace?

Once the furnace has reached the end of its life, it should be replaced. However, it can be hard to tell if the furnace just needs some repairs or a complete replacement. Here are five signs that it is time to replace the gas furnace:

  1. Frequent Repairs

If the furnace is needing more and more repairs each year, it’s probably time to replace it. Continuously repairing the furnace can end up costing more than installing a new furnace. Keep tabs on any repairs needed and talk to Diamond Heating and Cooling if they start to increase.

  1. Loud Noises

When the furnace starts to make noises it didn’t make before, there could be significant structural issues. These issues might be bad enough that the furnace should be replaced instead of repaired.

  1. Uneven Heat

A properly working furnace should be able to evenly heat the entire house. If some rooms are warmer than others, the furnace is to blame. The older it gets, the harder it can be for the furnace to evenly get warm air to the entire house.

  1. Higher Energy Bills

As the furnace loses efficiency, the energy bill will start to climb as it tries to keep up with heating demands. When the energy bill starts to increase, it might be time to ask about replacing the furnace.

  1. Age

Furnaces aren’t made to last forever. When it starts getting up there in age, around 15-20 years old, there’s a pretty good chance it will soon need to be replaced.

Homeowners noticing one or more of these signs should talk to Diamond Heating and Cooling about replacing their gas furnace.

Choosing a Furnace Filter

There are a lot of options available for furnace filters, which can be confusing for those trying to choose one. Looking at their MERV, cost, and how much it takes to maintain them can help homeowners choose the right one. Here’s a rundown on the different types of furnace filters:


These are the most basic style of filter and generally only cost $1. They’re MERV rating is between 1 and 4, which is not the best, but they will get the job done. Fiberglass filters do the bare minimum, which can work well in a household with minimal or no allergy issues, and for those who don’t mind changing the filter every month.


These filters have a higher MERV rating than fiberglass, landing between 8-13. They are great at trapping dust, a common irritant in homes, and they cost around $10. Pleated filters can usually be left in place for 3 months, which is good for households who might forget to change the filter out monthly. They are also the most commonly used.


Washable filters seem like a good idea in theory, but they have quite a low MERV rating (1-4) for having a price tag of $20. They are also known to collect fungus and bacteria. They are often avoided because of the maintenance required to keep them doing a good job.

Washable filters will work well for those who are diligent about washing and drying them extremely well to prevent bacteria and fungus.

High Efficiency

To remove the most air pollutants possible, get a high-efficiency filter. With a price tag of $25 and a MERV rating of 14-16, they are a great choice for many homes with allergies or asthma. However, these filters can be too restricting with air flow, causing efficiency issues with some HVAC systems.

High efficiency filters are a good choice for those who are worried about allergies and asthma when used in conjunction with the right HVAC system.

5 Ways to Make Your Home Cozier This Winter

Keep the dreary feeling of the winter cold away by making the house a little extra cozy. Just a few quick steps can make the house feel warmer and more comfortable for the colder months. Here are some suggestions:

  • Stop Drafts

Drafts can make the house even more chilly. Get a door draft stopper and weather-strip the windows to prevent cold air from seeping in. It also helps with energy efficiency.

  • Rugs

For homes with hard wood, tile, or linoleum flooring, winter can be hard on feet. Invest in some nice rugs for bare floors. They look nice and keep bare feet from becoming icicles.

  • Throws

Drape a throw or two over the furniture. They look as stylish as they are functional. Having extra throws around is perfect for snuggling under and warming up with a big mug of hot chocolate.

  • String Lights

Although most people decorate with lights outside during the winter, they can be used inside too. Hanging up some string lights in the family room or a bedroom creates a peaceful, cozy atmosphere that can be enjoyed during winter or all year long.

  • Pillows

Winter can be a great time to bring out those extra throw pillows and arrange them on the furniture. Pillows can add an extra layer of comfort and warmth when curled up on the couch or in a favorite chair.

The best way to make sure the house is cozy, is by having a properly-working, energy-efficient furnace. Talk to the team at Diamond Heating and Cooling to schedule maintenance or emergency repairs this fall and winter.
