3 Signs It Is Time to Replace Your HVAC System

Your heating, ventilation, and air conditioning (HVAC) system is a big investment and you have every right to expect it to do its work and last for decades, particularly with proper care and maintenance. Even so, your HVAC system will eventually reach the end of its productive lifetime and a replacement will be the right choice for your comfort and your wallet. These warning signs can signal that your HVAC system is failing and may need replacement:

  1. Frequent Need for Repair

Regular maintenance is a must for the efficient and continued operation of your HVAC system and small occasional repairs should be expected over the course of your heating and cooling system’s life. An increased frequency in problems or repairs could indicate it is time to consider a replacement, however; even minor repairs add up when repeated over time, eventually making replacing your system the economical choice. If you’ve noticed an increase in the frequency of your system’s need for repair or are faced with a major problem requiring costly repairs that are more than half the cost of a new HVAC system, replacement may be the smarter long-term choice.

  1. Rising Energy Bills

Ordinary wear and tear throughout your heating and air conditioning system’s life eventually lower the equipment’s efficiency and effectiveness, even with regular maintenance. Older HVAC systems have to work harder for longer to provide the same level of comfort they once did, leading to higher energy bills. If you notice your energy costs are rising, it may be time for an upgrade to a newer, more efficient HVAC system.

  1. Age of System

Sometimes the best indicator that you need a new heating and cooling system is simply the age of your system. Depending on use and maintenance, most HVAC systems only last about 10 to 20 years.  If yours is over 15 years old, it is probably time to start thinking about replacement to make sure you aren’t caught unaware and left without air conditioning on a hot San Diego day!

    I had no idea that the average HVAC system can last about 10 to 20 years. We moved into our house about five years ago. As far as I know the system has never been replaced. I’ll have to ask the previous owners if they know how old it is. Perhaps it is time to start saving to be able to afford a new one.

    I recently noticed that the energy bills in my home have been higher than usual the past few months and I couldn’t figure out why. According to the article, your heating and cooling system could actually start to loose efficiency due to age or other problems. I think the sooner I can get a professional to come out and look at it, the more money I could potentially save in the long run.

    It was really hot this summer, I assumed that it had to do with global warming. Then I read your suggestion that a system older than 15 years needs a replacement. The office that I work at is 18 years old so I am going to check with management about a replacement.

    Great article. It’s true that most homeowners are amazed to learn that their 15 year old A/C system is nearing the end of it’s life. We find it helpful to compare the operation of a cooling system to the operation of your vehicle. It’s something that you use everyday, and if you don’t take care of it with routine maintenance, you’ll more likely see issues occur.
