When To Replace Your HVAC Unit

Posted on Jul 1, 2020

Even with annual maintenance and regular checkups,  HVAC systems will age over time. At some point, you will have to replace the HVAC system in your home. Here is how to tell when it is time to replace the system and how to install a new HVAC unit in your home. 

Signs It’s Time To Replace Your HVAC Unit 

With our HVAC systems tucked securely in the walls of our homes, they often slip our minds. However, you may begin to notice some signs that your HVAC system is failing to perform the way it used to, and the usual DIY system inspection isn’t doing the trick anymore, which could mean it is time to replace the system. 

HVAC System Age 

Do you have any idea how old your HVAC system is? Many times, it has been there since you purchased the home, and you do not think too much about it. However, if you know your system is more than 15 years old, it could be a sign that it is time to replace the system. Many professionals recommend replacing your AC unit every 10 to 15 years. 

Breakdowns

Does it feel like you are dealing with repairs to your AC unit or HVAC system too often? If you are having to complete more repairs than you used to, you will notice those repair costs add up over time. Instead of continuing to repair a failing system, it may be time to replace.

Dust 

HVAC systems do not just heat and cool your home; they also provide ventilation and clean air. When your system is working properly, it helps remove pollutants from the air in your home. If you are noticing more dust and debris accumulating in your home, your HVAC system may not be doing its job. 

Humidity

In the same way that your HVAC system removes pollutants from the air in your home, it also helps maintain the humidity. This is key for homes in Hawaii, where we have more humidity than other states. If you notice your home feeling more humid than it should, your HVAC system may not be working properly. 

Noises 

HVAC systems should work silently behind your walls. You may hear the air moving through the vent or a quiet hum when the motor is running, but in general, the unit should be fairly quiet. As the system ages, you may hear strange noises like squealing or grinding, which you’ll want your HVAC service technician to inspect. 

Odors

You never want to smell an odd smell in your home, especially if it is coming from your HVAC system. While it can sometimes be your AC unit  burning dust off, it could also be mold in your ducts or even melting wiring. If you trace the scent to your HVAC system, you will want to have the unit inspected to see if it is time to replace the system. 

Cost

Is the price on your energy bills increasing? If your HVAC system is having to work harder to maintain the house, it will increase the cost of your energy bill. You can help prevent this with annual maintenance and cleaning, but as it gets older, you may need to replace it. 

Discomfort 

One of the easiest ways to tell if your HVAC system is aging is if you are no longer comfortable in your home. A home that cannot keep warm or cool may be a sign that the HVAC system is able to keep up anymore. 

Reasons To Replace Your HVAC Unit 

It may seem like you should hang on to your HVAC until it officially gives out once and for all. But there are a few reasons that you should replace the unit once you notice your HVAC system is starting to fail. 

Comfort 

A new HVAC system will improve air flow throughout your home or building. It can also better regulate the temperature throughout different rooms in your home, which can eliminate the issue of certain rooms being too hot or too cold. 

Air quality 

One of the most important jobs of your HVAC unit (besides keeping you cool in the hot Hawaii summer is to manage the air quality inside your home. HVAC systems provide the ventilation, maintain the humidity level and filter the air in your home. A new system will help better regulate the air quality in your home. New systems have add-ons such as home dehumidifiers, air purifiers and air filters that will improve air quality in your home. Because homes are built to be tighter and more energy efficient than they have been in the past, an HVAC system that purifies and removes pollutants from the air in your home is key. 

Smart technology 

New HVAC systems are constantly evolving and changing to incorporate new technology, such as smart devices. These devices and add-ons are more convenient and energy efficient than ever before. Smart thermostats can be programmed to fit your family’s lifestyle or adjusted from a phone app while you are anywhere in the world, so there’s less energy waste if you realize you left the heat on while you’re away on vacation. 

Value 

One of the things potential home buyers and inspectors always look at is the age and condition of HVAC units in the home. If you want to increase the value of your home, upgrading your HVAC system is an easy step.
