Furnace FAQs

We get a lot of furnace related questions! Here are our answers to some of the most common ones.

Furnace filters should be changed once every one to three months depending on the air quality in your home. A clean filter leads to a more efficient furnace, so if you start to notice problems with the heat in your home, start by inspecting the air filter.

If someone in your home as severe allergies or asthma, you may need to change your furnace filters more frequently to prevent dust and bacteria from entering your home through the furnace.

Many factors are involved in determining when a furnace should be replaced. You should look at the condition, age, efficiency, make, and model of the furnace to determine when to replace the unit. Most HVAC repair companies will recommend that furnaces are replaced every 10 years or so to keep up with new efficiencies. Cates Heating and Cooling offers furnace installation in the Kansas City area.

While yearly tune-ups and cleaning aren’t required, they will help extend the life of your furnace. These tune-ups also keep the manufacturer’s warranty active on your unit. Without annual maintenance, your warranty may be void. Having a technician come service your unit each year will ensure that your furnace is running at maximum efficiency. Additionally, your heat exchanger can be checked to make sure your system is running safely. Cates Heating and Cooling offers yearly maintenance programs to take the hassle out of calling someone out each year to look over your furnace.

Usually, getting a new furnace will save you money on your heating bill, but the main thing that saves you money is fuel consumption. Look for efficiency percentages to find out how much fuel is consumed by the make and model you are using.

Keep in mind that costs for fuel can be volatile, so even using less fuel may not always translate to a lower heating bill. While you should still expect to see less fuel usage on your energy bill, you may not be saving money.

In most cases, replacing a furnace is a same-day job. If there is any reason that your furnace replacement can’t be done within the same day, we will let you know and find a way to keep your home warm in the interim.

Unless you are an HVAC professional, it is unlikely that you will know the size of a furnace that you need in your home. A technician can help you determine the proper size of furnace for your home. A Cates technician will come to your home, evaluate the situation, and determine the right size of furnace for your home in a process called a heating load calculation.

AFUE, which stands for Annual Fuel Utilization Efficiency, ratings tell you the percentage of heat produced from a cubic foot of gas used. The remaining percentage is what is lost out the flue with biproducts. The higher the AFUE rating, the less you spend on fuel. All currently made furnaces must be at least 80 percent AFUE but furnaces older than 10 to 15 years might be less efficient.

Even though the furnace with the highest AFUE seems like the one you should purchase, there are other factors that you need to consider when you are shopping for a furnace. Electricity usage on for the fans and motors should also be considered.

Climate is a huge factor in selecting a furnace. If you live in a colder climate, you are more likely to see your savings within just a few years. In a more moderate climate, you might not see much savings on your heating bill. If you live in a moderate climate, you might want to get a mid-efficiency furnace.

A heat pump can be used to create heat and air conditioning. As an all-in-one system, many people find these pieces of equipment attractive. Learn more about heat pumps.

Units should never run when they are covered. A cover can impede airflow and damage the system.

Modulating heating utilizes a high-efficiency gas furnace with a modulating gas valve and variable-speed blower. These furnaces minimize energy usage by running at the lowest fan speed setting to reach the desired temperature in your home. Modulating furnaces produce the proper amount of heat to maintain a steady temperature in your home.

A variable-speed furnace refers to the air blower motor in the furnace. Learn more about variable-speed blower motors.

HSPF is the abbreviation for Heating Seasonal Performance Factor. This number tells buyers the heating efficiency of a heat pump. The higher the HSPF rating, the more efficient the heat pump.
