San Antonio Texas - Is it time to replace your HVAC system?

How can you determine whether you should repair or replace your home’s HVAC system? Without a fully functioning HVAC unit, it’s nearly impossible to live comfortably in the extreme climate of Texas. Here at Beluga Air, we provide top-notch service to San Antonio and the surrounding communities, from HVAC replacements and repairs to installations and maintenance. Below, we’ll explain the most important factors to consider whether an HVAC repair or system replacement is the right choice for you.

HVAC Replacements vs. Repairs: 3 Tips for San Antonio Homeowners

The $5,000 Rule of Thumb

How can you tell whether it’s better to spend money fixing the problem or if you should simply invest in a new system? Consider the $5,000 rule of thumb. Every system is different, and this rule isn’t hard and fast. However, it can be a useful tool to help you weigh in on your final decision.

The formula calculation is simple. You take the age of your HVAC equipment and multiply it by the estimated costs of repair. If the final number is under $5,000, you might be able to get away with a repair. However, if the total is over $5,000, your best bet is likely a full replacement and new system installation.

How Old is Your HVAC System?

The age of your home’s HVAC system is also extremely significant when making such an important decision. Units under 10 years old should have a fairly healthy lifespan left, making them a better candidate for repairs. Here’s the general life expectancy for the most common equipment types:

  • Heat pumps – 15 years
  • Furnaces – 15 to 20 years
  • Air conditioners – 15 to 20 years

For homeowners with HVAC equipment between 10 and 20 years old, you may consider the benefits of investing in a new system. You’ll enjoy greater comfort at home, improved air quality, maximum energy efficiency, and lower energy costs. The newer HVAC systems are a world away from what was available just 10 years ago.

System Maintenance and Warranty

Has it been more than a year or two since your heating and cooling equipment underwent professional maintenance or servicing? Neglecting regular maintenance can lead to frequent repairs, poor system performance, inefficiency, and rising energy costs. In most of these situations, upgrading to a newer, more efficient system is a smarter financial investment in the long run.

Does your HVAC equipment still have a valid warranty? If so, then read through the fine print and see if the repair costs are covered under the original warranty terms. However, if your warranty has passed its expiration date, then get ready to pay for this repair bill. A full replacement might be the best choice for you, particularly if you experience frequent breakdowns.
