Signs It’s Time to Replace Your Old HVAC System in Odessa, FL

replace your old hvac system tampa

There are nearly 100 million air-conditioned homes in the US. The number of sold HVAC units in 2024 could surpass 151 million. If you have an old HVAC system, you might need to buy a new one, too!

Here are the top signs you need to ask yourself, “Do I need a new HVAC unit?” If these issues sound familiar, find the best HVAC installers near me right away. Your Odessa, FL HVAC installers will get your new HVAC system running in no time.

Rising Bills

Americans spend an average of $2,284 per year on electricity and gas per household. About $1,346 is spent on space heaters or air conditioning. In Florida, annual spending reached $2,416.

Compare last month’s energy bill to a bill from the same time last year. Your most recent bill shouldn’t appear significantly higher. Rising energy bills are a sign you need to replace an old HVAC system.

Over time, your unit’s efficiency will decline due to normal wear and tear. Corrosion and the buildup of dirt within the unit will also affect its efficiency. As the unit’s energy efficiency drops, it will work twice as hard to function.

Components will continue to experience wear and tear. The entire unit might even break down.

You can expect the energy efficiency of your HVAC unit to drop by 5 to 10% as it ages. However, a huge spike in energy expenses indicates a serious problem. Consider hiring an experienced HVAC repair company.

They can review your unit to determine if they can make any minor repairs. They can also make recommendations to improve the unit’s energy efficiency. With help from your Odessa HVAC installers, you can save money and maintain your unit.

Uneven Temperatures

If you believe you have a failing HVAC unit, walk through your home. Do you notice the master bedroom is freezing cold while it’s sweltering hot in the living room? Your HVAC unit should maintain a consistent temperature throughout your home.

When an HVAC system is too large for a home, it will complete short cycles. The temperature will get satisfied too quickly. Then the system will shut off.

However, humidity throughout your home will remain. Some rooms will feel warmer and stickier than others.

If you notice uneven temperatures within your home, consider purchasing a new HVAC system. Newer systems can help you avoid uneven temperatures.

Your Odessa HVAC installers can also check your ductwork before installing the new unit. The ductwork carries cool and warm air to each room in your home. Make sure the ductwork can handle the amount of air the new system will move.

Constant Running

Your air conditioning system should shut off when it’s no longer needed. It might kick into overdrive to keep your home cool during hot summer days. If it doesn’t shut off on a normal day, however, it could indicate a problem.

Your Odessa HVAC technicians can determine if your air conditioner has the capacity it should. They might recognize there’s dirt that needs to be removed.

They might also need to clean or replace components.

It’s possible that the compressor isn’t functioning properly, which could cause the unit to shut down.

Let your Odessa HVAC installers know if your system isn’t reaching the desired temperatures. If it can’t reach the set temperature, the system will continue running. You’ll continue feeling uncomfortable in your own home.

If your HVAC unit is constantly running, you’ll also notice a rise in monthly energy expenses. Installing a new unit can help make your home more efficient.

Continuous Repairs

You’ll likely start asking yourself, “Do I need a new HVAC unit” if it’s in constant need of repair. Frequent repairs and downtime can become more common as the unit gets older. It could be more cost-effective to purchase a new HVAC system.

Talk to your Odessa HVAC technicians. They can review your unit and make recommendations.

For example, they might recognize that certain components need to be replaced. Components experience wear and tear over time.

Purchasing a new HVAC system will stave off the need for repairs for a few years. However, you should still maintain your unit. Routine appointments can help you catch small problems before they become major issues.

Carbon Monoxide Leaks

Carbon monoxide leaks can compromise your family’s health. A leak can occur within any system, but they’re more frequent with older units. A carbon monoxide leak could occur if your furnace rusts or parts fail.

Symptoms of carbon monoxide poisoning include:

  • Fatigue
  • Fainting
  • Drowsiness
  • Dizziness
  • Convulsions
  • Confusion
  • Chest pain
  • Weakness
  • Headaches
  • Breathing problems

If these symptoms sound familiar, don’t try to repair your unit alone. Otherwise, you could compromise your safety. An experienced HVAC technician can check for a leak and make the necessary repairs.


How long has it been since your original HVAC unit was installed? Most units run for about 15 years. The unit’s lifespan will vary based on how well it’s taken care of and if it was properly installed.

If it’s been years since someone last looked at your unit, call your Odessa HVAC technicians. They can offer preventative maintenance services. They can review your unit every six months to ensure it’s running properly.

If there’s a problem, they can make minor repairs instead of replacing the entire unit.

Preventative maintenance can help extend the unit’s lifespan and improve its energy efficiency. Schedule preventative maintenance checks during the spring and fall, before extreme temperatures roll in. Your HVAC technicians will ensure that your unit is functioning properly.

With their help, you can avoid needing a new HVAC system sooner than expected.
