When To Repair or Replace an HVAC System

Los Angeles, CA, homeowners rely on HVAC systems nearly every day. Whether it’s turning on the heater to get through those chilly November nights or running the AC for months at a time during the summer, these systems see a lot of use. However, every HVAC unit has a lifespan, prompting homeowners to ask when it’s time to repair or replace their HVAC system. Learn about HVAC lifespans, signs it’s time for repairs, and when to opt for replacement services from the pros at Service Genius.

How Long HVAC Systems Last in Los Angeles Homes

How long does an HVAC last in LA? While air conditioners generally last between 15 and 20 years, this lifespan is often based on data from areas that don’t get nearly as intense or long-lasting summer seasons. Here in LA, where your AC runs hard for months at a time, it’s not uncommon for air conditioner lifespans to max out around 12 to 15 years, especially without proper maintenance and care.

Heaters don’t see nearly as much action in LA, meaning you can expect them to last a few years longer than your typical air conditioner. Depending on the type of heater you have, you may be able to get anywhere from 15 to 20 years of reliable use out of it before needing to replace the system.

Key Signs Your HVAC System Needs Repair

Here are a few common HVAC issues that indicate it’s time to call for Los Angeles HVAC repair.

High energy bills

One of the most common symptoms of an HVAC problem is an increase in utility bills with no change in usage. Countless issues can cause an energy bill increase, but many, such as air filter problems or minor component damage, can be quickly repaired by the Service Genius team.

Inconsistent heating or cooling

Another common HVAC complaint is uneven cooling or heating in the home. If you notice warm and cold spots or poor HVAC performance at certain times of day, it’s a sign of a problem. Have the system inspected and repaired before you’re forced to spring for Los Angeles HVAC replacement.

Weak or no airflow

Weak or no airflow from HVAC ducts can be caused by a problem with the unit or by excess dust and debris in the ductwork (which also affects indoor air quality). Usually, this is easy for a professional to repair, but continuing to run the system without addressing the issue can cause severe damage.

Strange noises and smells

If you hear grinding, banging, screeching, or whining noises from your HVAC unit, it’s time to call for repair help before you wind up needing a new heater or air conditioner installation. The same applies to dusty, smoky, or mildewy odors, which may indicate the presence of debris, dust, or mold growth in your system.

Leaks

AC water leaks are typically a quick and simple repair for a technician. However, if your unit is leaking refrigerant, it’s a sign of a serious issue that requires immediate attention and repair. For gas furnaces, a leak is one of the worst-case scenarios. Shut off the gas, ventilate the home, and evacuate until a repair pro arrives if you suspect a gas leak from your heater.

When It Makes Sense to Replace an HVAC System

What are the signs that you need to replace an HVAC system? If your heater is having any of the following issues, there’s a good chance you’ll need to look into AC or heater installation instead of simple repairs:

• The system is nearing the end of its typical lifespan
• Constant shutdowns
• Recurring issues, either with the same components failing or new ones every time
• Consistently high energy bills compared to usage
• The system can’t cool or heat your home adequately

If your HVAC experiences these issues, repairs may only extend its lifespan slightly, without any significant change in performance, efficiency, or reliability. 

Repair vs Replacement Costs and Considerations

When considering HVAC repair vs. replacement, cost is often the main factor. HVAC equipment is a major investment, but when you consider the endless repairs on an aging, inefficient system, it’s actually more cost-effective in the long run to invest in a modern, reliable unit, especially when you factor in energy costs.  

How Energy Efficiency Impacts the Decision

A new HVAC unit saves you money through enhanced efficiency. This is especially true when deciding to repair or replace an air conditioner. On those hot summer days when you can’t escape to the Palisades, you’ll be running the unit for hours and hours at a time. Even a slight efficiency increase can result in significant savings on monthly bills, making a new HVAC system a worthwhile investment.

The Role of Regular HVAC Maintenance in Extending Lifespan

The best way to avoid the conundrum of repairing vs. replacing an HVAC system is to extend its lifespan through preventative maintenance. Prioritizing regular HVAC tune-ups helps prevent major issues from developing, improves system efficiency, and reduces the risk of shutdowns and other significant problems that could compromise your unit’s performance in the future.

Los Angeles Climate Factors That Affect HVAC Performance

LA’s hot, humid summers can put a lot of strain on air conditioners, forcing them to run harder to cool your home. HVAC systems need maintenance at least once a year, and even then, they might have a slightly shorter lifespan than in milder parts of the country. On the other hand, furnaces may last a little longer thanks to LA’s mild winters.

Benefits of Installing a New HVAC System

A new HVAC system offers numerous benefits for LA homeowners, including superior efficiency, better reliability, and a reduced risk of sudden HVAC shutdowns, all while providing consistent heating and cooling throughout your entire space. While the upfront cost can be substantial, your new unit should pay for itself within a few years with proper maintenance.
