Furnaces leave many signs that they're close to breaking down and require replacement. One of the most common indicators is strange noises, such as screeching, humming, popping, and rattling. In addition, temperature shifts are widespread in older furnaces and may also necessitate installing a different model. As the system ages, its efficiency gradually reduces, losing the ability to circulate heat evenly throughout the house.

The average lifespan of a furnace is between 15 and 30 years. Even though some products can last for over 40 years, most units don't make it to this age. As a result, the life expectancy varies by model, but several other factors have a considerable bearing on a furnace's longevity. For example, improper furnace sizes, faulty installations, improper or non-existent maintenance, and ill-advised thermostat settings can lead to a breakdown much sooner.

Many aspects determine how often you should replace a furnace filter, and the most critical factor is the size. For example, one to two-inch filters should be replaced once every three months, whereas five to six-inch filters need replacing once every nine months. The number of occupants is also an essential consideration. The more people in the house, the more often the furnace filter should be changed.

Switching to a high-efficiency furnace is a wise investment for many reasons. Primarily, these products can cut electricity bills by as much as 30%. In addition, high-efficiency furnaces feature systems that remove moisture and can endure chemical build-up, dramatically prolonging their lifespan. These systems also use advanced technology with sound-absorbing materials and gas valves, ensuring better and more consistent heating.

Several factors may be responsible for cold or lukewarm air coming from a furnace. Most notably, the thermostat might be set to cool. The fan should be adjusted to "auto," enabling it to coordinate the mode with the furnace and expel hot air. Additionally, the filter might be too dirty and clogged, preventing the system from performing adequately.

A strange sound coming from the furnace is rarely a cause for concern. If the heater is rattling, it might mean one of its panels is loose. However, if the panel is fine, the sound may be produced by the expansion and contraction of metal components. Temperature changes make them heat up and cool down, producing strange noises.

The most obvious reason people need a new heater is if it's more than 15 years old and faces recurring issues. But even if it seems to be operating problem-free, it's doubtful the system is performing at maximum capacity. Other indicators you might need a new heater include uneven temperature distribution throughout the house, rising energy bills, and frequent repairs.

Turning the heating system off in the summer is highly recommended for many reasons. Specifically, it helps prevent unnecessary energy consumption caused by running sensors and other components. For example, the pilot light on the furnace burns gas around the clock, leading to gas waste and higher electricity bills. Therefore, shutting the unit off during the summer is a great way to save energy and up to $50 every year.

• Poor/Faulty Wiring: Wiring is one of the most critical steps for an expert during HVAC installation. Haphazard wiring can result in a fire or compromise the efficiency and durability of a system. The Above & Beyond Air Conditioning & Heating technicians can check the wiring to determine it was done correctly. If it was not, we have the tools and expertise required to rewire the entire system. After the service, we will check if the system receives enough power and the internal components are upbeat.

• Faulty Outside Fan: Most of the air conditioning system components are installed outside the house. The fan helps to facilitate airflow in and out of the system. The system will not cool the space if the fan motor isn't working or the compressor fails.

• Frozen Coil: If the coil is frozen, there is a high chance that the air is not flowing as it should be. Worn or dirty filters are sometimes the cause. An obstructed air ductwork can contribute to a frozen coil, as can a lack of refrigerant. An Above & Beyond Air Conditioning & Heating technician can determine the cause of the problem and resolve it to restore the system.

• Dysfunctional Outside Unit: All air conditioning system components rely on the outside unit. If the exterior unit fails, the entire system shuts down. Lack of power, poor installation, and faulty thermostat are possible causes of this problem. The Above & Beyond Air Conditioning & Heating technicians can correctly solve any exterior air conditioning unit problems.

• Low Refrigerant: Refrigerant is a chemical that helps cool air inside the air conditioning system before circulating the air into the rooms. Low refrigerant levels can lower the system's efficiency. Our experts can check the refrigerant levels to determine if there is a leak that needs repair. Once the problem is identified and the system repaired, the technician can refill the refrigerant.
