If you live in the Greater Los Angeles area or anywhere in Southern California, you know it’s important to have a reliable HVAC unit to keep you comfortable. However, if your current system isn’t working like it should, it might be time to schedule a replacement. The experts at Fleetwell Air Conditioning, Heating, and Plumbing have some helpful information that explains the best time of year to replace your HVAC system for maximum benefits.
Best Time of Year To Replace HVAC: Spring and Fall

Just like routine maintenance, the best time to replace an AC or heating system is in the spring or the fall, depending on your needs. There are many reasons why knowing when to replace your HVAC system and choosing the right time to schedule installation is so important, and we’ll go into more details about those reasons later.
When To Replace Your AC Unit

There’s nothing worse than a malfunctioning air conditioner, especially when it happens right amid the peak Southern California summer heat. Replace your AC unit before it fails in the middle of the summer. If you suspect a serious issue with your air conditioner, we highly recommend scheduling a replacement as soon as possible. The longer you delay upgrading a malfunctioning system, the more expensive and stressful things will be as time goes on.
Scheduling a new AC installation as early as possible is a smart way to make sure that your new air conditioner is available and prepared to give you reliable, consistent indoor cooling all season.
Why Timing Matters When Replacing Your HVAC System
Timing matters when it comes to replacing your HVAC system. Here’s why it’s so important to choose the best timing possible for your HVAC upgrade with Fleetwell Air Conditioning, Heating, and Plumbing.
- Short (or no) wait times: When you time your HVAC installation right, it’ll get done faster since demand is lower in the fall and spring, meaning there should be shorter (or maybe even no) wait times.
- Better pricing: Because demand is lower in early spring and fall, you should get a better and more affordable price on your new HVAC system installation.
- You’ll prevent costly breakdowns: If your current HVAC system is facing issues, upgrading it early will help you prevent paying for more expensive breakdowns later.
- Peace of mind: If you’ve already been thinking about replacing your HVAC system, doing it early gives you peace of mind and confidence knowing your home will be comfortable all summer or winter long.
- Optimal performance: Replacing your HVAC system early is the best way to make sure that it’s performing optimally before the peak winter or summer season begins, and you can make adjustments as needed.
- More energy savings: Upgrading to a new, more energy-efficient HVAC system helps you save money on your monthly energy costs, which is especially important during summer and winter when you use the system the most often.
- Better availability: Not only will you have better scheduling slots available, but there’s likely a wider selection of brands and HVAC system styles available if you schedule your installation earlier.
Signs It’s Time to Replace vs. Repair Your HVAC
You may wonder whether it’s time to repair your HVAC system or replace it altogether. Look for these common signs that often indicate you’re better off scheduling a full replacement.
Aging system
The average lifespan of most HVAC systems is between 10 and 15 years. Even if your system is well-maintained, most HVAC systems start to break down as they age due to wear and tear. Replacing an aging system that’s at least 10 years old or older is the best way to get maximum energy efficiency, optimum performance, and consistent reliability.
Frequent repairs
While the occasional need for a minor, infrequent AC repair is normal, paying for frequent repairs is a sign that something is wrong. If you’re starting to pay for repairs more often than normal, you may want to consider a full HVAC replacement instead. The 50 percent rule states that if the cost of repairs reaches 50 percent or more of the cost of a new system, it’s better to schedule an upgrade.
High energy bills
It’s perfectly normal if your monthly utility bills are a bit higher in the summer and winter. However, if those bills seem to skyrocket suddenly without a noticeable change in HVAC system usage, there’s a good chance a serious underlying problem is taking place. A major decrease in energy efficiency could be due to a refrigerant leak, a malfunctioning component, or another issue that’s best remedied with a full replacement.
Noises or odors
Strange, loud noises like banging, screeching, hissing, or grinding coming from your HVAC should never be ignored. These noises likely indicate there’s a major issue with important parts like the compressor, condenser, or another component that should be repaired or replaced. Unpleasant musty odors are a sign of a leak or condensation issues, while chemical smells could be associated with a refrigerant issue. Depending on the severity, these issues might best be resolved by replacing the entire system.
Performance issues
A “healthy,” well-maintained HVAC system should provide your home with even, consistent heating and cooling. If you notice a drop in performance, your system needs to be repaired or replaced as soon as possible. Problems like uneven heating/cooling, humidity issues, a reduction in indoor air quality, or short-cycling should be investigated by an HVAC professional.
Don’t Wait: Plan Ahead for Your HVAC Replacement
Replacing your HVAC system in spring or fall is a much better time than in the summer or winter. By planning your replacement in advance, you’ll reap significant savings, have access to better scheduling availability, and you’ll have access to more options. The average time to install a new HVAC system is between four and eight hours, but it may take one to two days depending on the complexity, the size of your home, and other factors.
Here are some tips to help you plan ahead for your HVAC replacement.
- Run your HVAC system before summer or winter to see how it performs and if you notice any major issues, consider scheduling a replacement as soon as possible.
- Schedule routine maintenance to protect your current system and keep it running smoothly if you’re not ready to pay for a replacement this year.
- Ask the Fleetwell team about discounts, incentives, and other ways to save on your HVAC replacement so you can take advantage of them now before demand increases.
- Research different HVAC system brands and types so you know exactly which one is best for your home and comfort needs.
- Schedule a consultation with Fleetwell and get an estimate for your HVAC replacement so you’re prepared for the cost (flexible financing options are available).
