Signs Your System Needs Replacement

While each HVAC system is unique and there is not always a set standard for when a HVAC system replacement is required, there are several signs that you can look for to help you decided if HVAC system replacement may be a wise financial investment. Some of these signs to keep an eye out for include:

If it has been more than 10 years since you bought your air conditioner unit or heat pump, or if it has been more than 15 years since your furnace or boiler has been installed, then it is definitely time to consider HVAC system replacement. HVAC systems are a constantly evolving industry, and HVAC equipment is frequently updated using new technology to offer better energy efficiency and performance.

The sustained, quiet hum that your air conditioner or heater makes is often an indication that it is running. However, there are certain noises that may mean HVAC system replacement is necessary. For example, a sudden hiss could indicate a coolant leak or faulty ductwork. Loud thumps on your equipment are also a sign that something is wrong. If you are not able to determine the cause of the noise, turn off your unit and call to schedule a service appointment.

If you start smelling something that is similar to overheating, this could be due to faulty electrical wiring and could be a sign you need HVAC system replacement. Additionally, if you experience a burning smell coming from your furnace, this could be due to a gas leak. If your nose is able to detect a dusty, moldy smell, this could be due to mold buildup within the air duct. Any of these smells may be strong indicators of safety hazards. If you smell something unusual coming from an HVAC system, you should turn it off and then contact an HVAC professional immediately to discuss HVAC system replacement or repair.

While it is absolutely normal for your utility bills to increase over time, if the increase is significantly larger than the previous months, HVAC system replacement can save on your bills by swapping your old unit with a more energy-efficient system. HVAC equipment can lose its efficiency over time, and this will be aggravated if your equipment is not maintained properly.

If you are already on a first-name basis or on friendly terms with an HVAC technician because he frequently visits your home to do repairs, then you should consider HVAC system replacement. Frequent HVAC repair costs can easily add up, while buying an HVAC system is a one-time cost. Therefore, HVAC system replacement will save you more money in the long run than having to make do and pay for frequent repairs.
