Wondering whether you need to replace your HVAC system? Maybe you have seen a few signs and want to know if they should be taken seriously, or maybe you just think a lot of time has gone by since you bought it. Rest assured, your home will stay a comfortable temperature with the proper care. Here are five signs to pay attention to so you know when the time to replace your HVAC has arrived:
1. High Repair Costs
A good rule of thumb is if any single repair costs half as much as it would cost for a new AC unit, you should replace your HVAC. High repair costs could also be due to smaller repairs or part replacements that increase in frequency, so if you notice you have to call in your maintenance team more often, it is time to consider a new system.
2. Creeping Utility Bills
Another sign that you should start looking to replace your HVAC system is if you notice a steady increase in your utility bill. Look beyond seasonal changes by comparing your energy usage to what it was last year at the same time. If you notice three consecutive months where energy usage is higher than the previous year without a specific cause, get your HVAC looked at to see whether it is to blame.
3. Funny Noises
Your house is probably not haunted, so if you hear funny noises, they could be coming from an old HVAC system. Common HVAC sounds include revving, grinding, squeaking and clicking. Those noises may be creepy or funny, but if your HVAC is making them, it means the system is working inefficiently and should be replaced.
4. Poor Air Quality
Your HVAC system is responsible for heating and cooling, but also for filtering the air and keeping proper ventilation so the humidity stays outside. If you notice dust, dirt, allergens or high humidity in your home, it is a sign the HVAC system is no longer doing its job efficiently. There are a variety of reasons for this, ranging from clogged air filters to cracked pipes, and all of these require immediate professional attention.
5. Age of the System
Like all machines, your HVAC system wears down over time. Another rule of thumb is to have your system checked for replacement once it reaches 10-15-years-old. The exact amount of time will depend on how well you maintain the system and whether certain parts may be phased out and obsolete. For instance, HVAC systems using R22 refrigerant are being phased out by 2020.
If you have had your system for a decade or more, you are unsure of the system’s age, or you are concerned your system may be becoming obsolete in the near future, get a professional to inspect it right away.
With these telltale signs, you’ll have a better idea of when your HVAC system will need to be replaced to keep your home at the perfect temperature in every season. A healthy HVAC system is an efficient one — make sure yours is doing its job well.
