Signs You Need a New HVAC System

Deciding to replace or repair an HVAC system can be difficult. At United Air Temp, we recommend our customers install new equipment in these situations:

  • System age: Every type of HVAC system has a different lifespan. If your unit is over a decade old, a replacement will provide greater reliability, performance, and energy efficiency. 
  • Repair frequency: If you’re calling for costly repairs often, it may be a better financial decision to replace your system with one that’s more reliable and is backed by a warranty.
  • Repair costs: Homeowners should use the 50% rule when considering replacement. If the repair cost for your system is more than 50% of the replacement cost, it’s better to upgrade.
  • Improperly sized unit: An HVAC system that isn’t the right size for your home will struggle to keep your house at the right temperature but also won’t be as efficient. 
  • Infrequent maintenance: If you haven’t kept up with preventative HVAC tune-ups, your system is more likely to have advanced wear and tear.
Request Service Get started by filling out a service request form or by giving us a call.

What Our Clients Are Saying
testimonial_image The tech was at my home less than 10 minutes and gone within 20 minutes due to having my A/C up and running. I really appreciate his response to my home and working with my son due to me being out of town, but we spoke on the phone.
testimonial_image The technician arrived promptly, wore a mask, was very courteous and professional. I am generally very satisfied with service by United Air Temp. In addition to good service (they repair well), it is easy to speak to a person, and promptly. Thank you.
testimonial_image Great service! I called because I was under the impression the AC was not working upstairs. Someone came on the same day, checked out the system, and ensured everything was working. He was polite, thorough, and friendly.
testimonial_image Tech was very attentive and professional. He went out his way to explain everything to me as he was doing it. I appreciated him keeping me informed.
testimonial_image The service technician was awesome! He spent the extra time necessary to ensure the leak in our system was fixed, the system fully recharged and everything was functioning as it should. He was extremely thorough and very professional. We are extremely pleased with the result!
