One of the most significant home investments you may make is the HVAC system, which consists of the appliances used to cool and heat your house. Your home’s HVAC system is in charge of keeping the air inside clean, dry, and very comfortable to live in. If the system is malfunctioning or outdated, major issues may arise.
But how can you decide when to upgrade your home’s HVAC system? And how can you maintain the HVAC system you require so you won’t have to replace it occasionally? Read on for answers.
HVAC System Lifespan by Type
The HVAC useful life varies depending on the type. The following are the typical life periods for standard HVAC equipment:
Although most air conditioners survive 15 to 20 years on average, others only last 10 years. They often only live seven to twelve years in coastal areas due to salt penetration. Air conditioners and heat pumps are often replaced if the compressor breaks down, or the condenser suffers from significant corrosion and leaks.
Boilers can last anywhere between 20 and 35 years, which is a substantially longer lifespan than furnaces. The heat exchanger is often changed if it starts to leak.
Depending on how often they are utilized, heat pumps can last between 10 and 20 years, though 15 years is more typical. Heat pumps with seven to twelve years lifespans are similarly susceptible to premature failure in coastal environments.
Ductless mini-splits can provide heating and cooling, except in coastal areas, and have a typical lifespan of 10 to 30 years.
Factors That Affect HVAC Lifespan
A domestic HVAC system typically lasts mainly between 10 and 20 years, but let’s check some factors that might alter this range.
Your cooling and heating equipment’s projected lifespan will vary depending on only a few factors, such as:
- The existing configuration of your home’s HVAC system
- Whether it has a furnace or a boiler
- Having the right insulation quantity in your house
- Regularly doing major HVAC tune-ups
- The preferred temperatures in your home
- Your region’s weather
HVAC System Maintenance
To give you the best tips on HVAC system maintenance, we talked with and expert; Andrew Smith from elevation-mechanical.com. Let’s look at what he said are the critical measures you must constantly follow to ensure the proper working of an HVAC system.
Clean the Heat Pump or Condenser
Outdoor HVAC systems and heat pumps are susceptible to significant damage, making the system work much harder to produce the desired warm and cold air in your house.
Adequately cleaning heat pumps and condensers lowers the risk of internal component damage. Households must ensure that the sides and top of their outdoor HVAC units and pumps are free of debris. Utilize your garden hose to clean the fins, being careful to reach all the crevices and remove all the dirt.
Verify Your Filter
A filthy air filter is an obvious cause of air conditioner repair. Filter check is a simple HVAC maintenance task to increase the effectiveness of the air conditioner, lower home heating costs, and lower the probability of repairs by changing the filter.
Every month, make sure your filter is clean and unclogged. If so, it would be wise to run a thorough cleaning on it and blow air over it. The filter should only need to be changed roughly every four months. Replace it right away if it looks dirtier than usual, especially if you have pets in your house.
Yearly Professional Examinations
An HVAC specialist will visit the location as part of check-ups to inspect the HVAC system, ensuring it performs at its best. The inspection involves performing the following activities, depending on the technician involved:
- Making sure the AC fan is functioning properly
- Coils cleaning
- Examining (or perhaps replacing) the filter
- Cleaning drain lines
- A refrigerant level check
- Examining the heat exchanger for leaks
- Squeezing out the drain lines
How Often Should You Replace Your HVAC System
After ten years, air conditioners and heat pumps can start malfunctioning more frequently and lose efficiency. At the ten year mark It’s time to evaluate and consider HVAC repairs or replacements.
Depending on several variables, an HVAC unit lasts between 10 and 25 years. Your system may appear to be functioning if it is over ten years old, but could end up costing you much more money and have grown much less effective.
Signs You Should Replace Your HVAC System
As an HVAC system owner, there are some signs you should pay attention to maintain a perfectly working HVAC system and also provide answers to the question “how often should you replace your ac unit?”. Some of these signs include:
Your Energy Costs Are Increasing
Your HVAC system is working too hard if the energy prices rise yearly, whether they are summer cooling costs or winter heating bills.
The normal lifespan of an HVAC system is between 10 and 25 years, but if the HVAC system has been actively overworked by poor insulation and undesired airflow, it may last a shorter time. Only a qualified energy audit will reveal whether your HVAC system is overworked and underperforming. Through Sealed, you could be capable of receiving an energy audit.
You Don’t Have Very Good Indoor Air Quality
Do you happen to have a lot of excess dust that flies through the air in your home at the point where the sun comes through the windows? This is a sign that the HVAC system doesn’t efficiently filter the air in your home.
It’s time to transition to a more hygienic, better HVAC system if your home’s air quality is declining, even if your heating and cooling system still has a few years left.
You Are Paying a Lot for HVAC Repairs
A typical component of maintaining household appliances is routine maintenance and the occasional repair of the HVAC system.
But it’s in your interest to invest those dollars in a good replacement if you frequently spend money on expensive repairs for your heater or air conditioner.
You Don’t Feel at Ease in Your House
Are you both too hot and cold in the summer and winter? Do any areas of your home have drafts or differing temperatures? This is typically a sign of a larger issue with the HVAC system that affects the entire house.
The HVAC System Uses Fossil Fuels to Operate
It’s probably time to have your outdated heating and cooling system replaced if it runs on fossil fuels (such as heating oil or natural gas). Electricity tends to be a less expensive, more efficient, and cleaner energy source when employing modern HVAC systems.
Fuel for heaters is expensive, and geopolitical circumstances frequently influence the main price. It is expensive, uses less energy, and raises the danger of breathing in toxic compounds like carbon monoxide.
