It’s no secret that HVAC units play a crucial role in our everyday lives. Not only do they keep us comfortable, but they also help to improve air quality and protect us from airborne pollutants. But what happens when the HVAC suddenly stops working on the hottest summer day? While HVAC units are built to last, they eventually need to be replaced. So, when is the best time to install new HVAC equipment?

Signs It’s Time for a New HVAC Unit

It’s no fun when your heating and cooling system quits unexpectedly. But you can avoid the headache and expense of a sudden HVAC system replacement by knowing a few telltale signs that indicate your HVAC unit is nearing the end of its lifespan and needs to be replaced.

Your Energy Bills Are Increasing

If your energy bills are gradually increasing each month, it could be a sign that the unit’s compressor or motor is wearing out, and the HVAC is becoming less efficient.

Less Airflow in the Room

If you’ve noticed a decrease in airflow from your HVAC unit, it’s probably due to a buildup of dust and debris on the coils. This problem can happen when the HVAC unit isn’t serviced regularly. If left unchecked, this will cause damage to the HVAC motor.

HVAC Unit Is Making Strange Noises

If you start hearing strange noises from your HVAC equipment, it’s a sign that something is wrong. These noises indicate that the bearings are wearing out or debris is caught in the fan. If you hear these kinds of noises, it’s best to call a professional to take a look at your HVAC unit.

Refrigerant Leaking From the HVAC

Refrigerant is a cooling fluid used in air conditioning systems to transfer heat and to keep the temperature inside the cooling unit consistent. However, the refrigerant can leak out of the system over time. Eventually, the HVAC unit loses its efficiency and stops working altogether.

How Often Should You Replace Your HVAC Unit?

Ideally, you should replace your HVAC unit every 10 to 15 years. However, some factors can affect how often you need to replace your unit. These include:

The Type of HVAC You Have

Central air conditioners generally have a lifespan of 15 to 20 years, while furnaces typically last 15 to 30 years. Ductless mini-splits have a shorter lifespan than central air conditioners. One of the biggest differences between central air conditioners and ductless mini-splits is how they distribute air.

Ductless systems rely on an indoor air handler unit connected to an outdoor condenser unit with a small diameter refrigerant line. Although these systems are less complex than central air conditioners and have fewer moving parts, the smaller refrigerant line is more susceptible to leaks, which can shorten the system’s overall lifespan.

Your HVAC Unit Size

The HVAC size in relation to your home footage is also a factor. If your HVAC unit is too small or too big for your property, it will have to work harder to maintain the desired temperature, which can shorten its life span.

If your HVAC unit is too small for your home, it must work harder to heat or cool the same amount of space, which puts more wear and tear on the unit. As a result, small HVAC units typically don’t last as long as an adequate size unit.

On the other hand, having a unit that is too big for your property can also lead to premature unit failure. The main reason is that HVACs generate a lot of heat, and bigger units must work harder to cool down a space. At the same time, the temperature sensor can trigger the unit to constantly switch on and off, causing the system to overwork. You can avoid these issues by having a professional HVAC contractor size your system properly before installation.

The Climate

HVAC units don’t just wear out from use, they also corrode from the humidity in the air. Unfortunately, HVAC units in parts of Missouri have to work harder than HVAC units in many other places because of the high humidity. Your HVAC unit needs to work harder to pull excess moisture out of the air and keep the house cool in the summer and warm in the winter. As a result, HVAC units in St. Peters and St. Louis generally last about half as long as those in other parts of the country, and you may need to replace your HVAC system every few years.

Air Pollutants

HVAC systems are essential for regulating our homes’ temperature and air quality. However, HVAC units can become clogged with dust and other pollutants, reducing efficiency and requiring frequent filter changes. This issue is especially important for homeowners in St. Peters and St. Louis. The cities’ location near the Mississippi River and their industrial history mean that air pollution levels are higher than average. As a result, residential HVAC units tend to collect more pollutants and require frequent filter changes. Homeowners should be aware of this issue and take steps to ensure that their HVAC units are operating at peak efficiency.

How Often to Service Your HVAC

Lack of maintenance is one of the main reasons HVAC systems need to be replaced sooner than expected. It’s important to have your HVAC unit serviced at least once a year by a professional to help prolong its lifespan. Servicing includes cleaning the unit, changing the filters, checking for wear and tear, and ensuring that all the parts are working properly.

Benefits of Changing Your HVAC During the Off-Season

HVAC systems work hard to keep us comfortable in our homes and businesses. But like any mechanical system, they require regular maintenance to run efficiently. Many people wait until the summer or winter to change their HVAC filters and units, but did you know it’s better to do it during the spring or fall?

The off-season is usually the best time to do it. HVAC contractors are typically less busy during these months, so they may be able to give you a better deal. At the same time, depending on your home footage, the contractor may require several days to complete the job. If your HVAC is replaced during the summer, you may have to go without air conditioning for a few days. But if you have it done during the spring or fall, the weather is usually mild enough that you won’t need AC or heat.
