A furnace can last anywhere from 15 to 20 years depending on the make, model, and how often it receives a tune-up. Your furnace should receive a maintenance tune-up once a year. Older furnace systems use much more energy to function and can run into more issues than modern units. The more wear and tear your system takes on to operate, the less time it’s going to last overall, this is why it’s important to get annual inspections.


An air conditioning unit should last anywhere from 15 to 20 years with annual maintenance performed each year, and depending on the make and model. The older your system is, the more energy and wear and tear will be required for it to run. Neglecting your system when you notice inconsistencies will only damage it more over time and shorten its lifespan. Annual maintenance is the key to a longer-lasting air conditioning system.


The things that can cause an air conditioner to freeze up can include a dirty filter, improper airflow across the evaporator coil, and a low refrigerant charge. If your air conditioner is showing low refrigerant levels, it might be leaking. Furthermore, ice will start to form around the unit. Without proper refrigerant levels, your air conditioner won’t operate as it should, causing any water vapor to freeze up on the surface of the evaporator coil.


The thermostat fan setting could be set to ON, which will run the blower continuously. More than likely you have an issue with a part that is not allowing the furnace to ignite. When your furnace starts blowing cold air, this means there’s a problem with the flame detector, gas supply, air filter, pilot light, or condensate lines. All of which need the expert care of an HVAC technician.


If you find that your air conditioner starts leaking water, you must turn off your system immediately and contact our skilled team at Bel-Aire Heating & Cooling. Failure to turn off your air conditioning system can result in a break down from the system flooding. Simply cut power to the system, and give us a call ASAP!


The difference between tankless water heaters and regular water heaters is that tankless heaters heat water without using a storage tank. When you turn on hot water from your faucet or shower, the water starts out cold before entering through the heat exchanger, then either a natural gas burner or an electric burner will heat the water.


Depending on water quality and maintenance average of 15 to 20 years. A tankless water heater’s average lifespan is based on how often it is used and if it is tuned up at least once a year. Addressing inconsistencies with your tankless water heater when they occur is also key. Tankless water heaters don’t experience as much damage from water corrosion as regular water heaters do. While a traditional water heater can last up to 12 years, a tankless water heater can last about 20.


First you’ll need to figure out the size of the room in square feet. You’ll need to measure the length and width of the room then multiply. Then measure the distance between the wall and the center of the room. Multiply that number by itself, then again by 3.14159.

Now you’ll need to convert the square footage measurement into BTUs. In order to figure out the amount of BTUs (British Thermal Unit) needed produce hot or cold air, multiply the room’s square footage by 25.

For each room you plan to use your ductless mini split in for heating and cooling, you will need to repeat the process.


Geothermal energy is renewable. It is a natural source of heat that comes from the Earth’s core. Within the core, there is a notable amount of thermal energy some of which is accessible near the Earth’s crust. This all natural source of power makes geothermal energy renewable and reliable. Geothermal energy is environmentally friendlier than other sources of power, and is ideal for counteracting climate change.


On average, boilers tend to last about 15 years. Without annual tune-ups or ignoring problems when they occur, your boiler will experience more wear and tear and won’t last you nearly as long. For a boiler system that lasts, you need to keep up with maintenance each year. If your boiler is older than 15 years, it’s probably time for a replacement.
