Should You Repair or Replace Your HVAC System?

Typically determining whether you should repair or replace your HVAC unit will really depend on the condition of your current system. If your heater or air conditioner is newer or the problem is minor, then repair is usually the better option. Conversely, older systems that require more major service may be more suited for replacement. While repairing your existing system may seem like the most cost-effective choice, if it is not functioning properly and efficiently, you could end up spending more money in energy costs and repeated repairs over time. Replacing your system with a new model provides greater efficiency benefits which can lead to long term savings on utility bills. 

Signs Your Heater or Air Conditioner Needs Service:

  • If it is no longer producing any air or airflow is weak
  • If it is continually cycling on and off
  • If your home is starting to gather more dust than usual
  • If it is producing uneven or inconsistent heating and cooling
  • If it has developed a water leak
  • If your property’s humidity and comfort levels have changed
  • If it is leaking refrigerant 
  • If it is making loud or unusual noises when running
  • If your energy bills have suddenly and significantly increased

With so many factors to consider, it’s best to consult with our experienced La Jolla HVAC technicians. We will be able to inspect your current system to determine whether repair or replacement is the better route to take, while performing the necessary service.

Frequently Asked Questions
  • Should I replace or repair my AC unit?

    Many customers ask if they should repair a broken air conditioning unit versus a full replacement. Often, a well-maintained and newer AC unit will be able to be repaired depending on the issue. If it is a part under warranty, replacement of the part is a simple fix. However, if the AC is more than 10 years old, has not been regularly serviced, or is in need of a major repair, replacement is the best option. Our team will provide all available options for homeowners to consider.

  • What's a Pre-Installation Evaluation? Does My New A/C Need One?

    In short, yes. A first step is conducting an energy audit to determine the energy load for your home. Calculating the load tells the experts at John Stevenson Plumbing, Heating & Air how much heat your house gains throughout the day & what size air conditioner will work best to keep it cool. This is critical as most A/C installation issues stem from an improperly-sized air conditioning unit.

  • Is Your Home's Ductwork & Design Able to Handle a New A/C System?

    Often your old, existing ducts can’t handle the airflow of a newly installed air conditioner. Any upgrades to accommodate a new system will likely increase the cost to install an A/C unit, but will ultimately help you avoid costly, high energy bills & hot rooms in the future.

  • What Type of Central A/C Unit Should I Install?

    Here’s where the load calculation comes into play, as you want to pick the right size A/C unit to install – either too big or too small of an A/C unit can lead to costly repair or replacement down the road. Call the HVAC professionals at John Stevenson Plumbing, Heating & Air, they’ll know which A/C unit is perfect to install in your home at the lowest price.
