Air Conditioning FAQs for O'Fallon, IL Homeowners

You probably have a lot of questions about Weis Heating and Cooling and AC repair in general. Here you can find an in-depth FAQ about HVAC systems and how you can prep for summer.

  • Should I leave my fan on?: Typically, an air conditioner's fan increases the humidity in your home if left "on." You can save power during the spring-summer transition by keeping it on "auto."
  • Should I try and troubleshoot any problems before calling?: If the system isn't working, you can replace the batteries in your thermostat. The most common problems are float switches, filters, and breakers. If you don't know what you're looking at it's advisable to call for service.
  • Why would I need AC repair even if I don't use it? Your entire HVAC system accumulates dust in air filters and condensing coils. Your AC system alone can lose an average of 5 percent efficiency over the course of a year and cost you hundreds of dollars in damages. This is avoidable with regular maintenance and cleaning.
  • How long should my air conditioner last?: This varies on the brand. Typically, an AC unit is expected to perform for 10-20 years if it's properly maintained. Call for seasonal maintenance to make the most of your investment.
  • Is it better to leave my AC on if I'm away?: Unless you're out for a few days, it's advisable to leave your AC on. Leave it on a reasonable temperature (mid-70s) and set the fan to "auto".
  • Why is SEER important?: A system's SEER rating is its estimated efficiency. Most AC units start at 13 but 17-20 is average. We can calculate the estimated dollar savings based on the SEER number.
  • When should I check my filters?: If you're hands-on and know how to do it, every month or two. More residents or pets can increase how much debris gets in the filters. It is also important to keep track of when you change them; our O'Fallon, IL, AC repair technicians will ask.
  • When should I get my AC looked at?: Typically, you want to have your systems checked out once a year. Spring is a great time to do this. You can request service and set up an appointment with Weis Comfort Systems today.

Keeping your AC system healthy is a money-saver. If you need emergency AC repair in O'Fallon, IL, do not hesitate to reach out to Weis Comfort Systems. Our technicians are trained, certified, and experienced.

Why Do I Need an HVAC Inspection?

Mentioned above, getting entire HVAC system inspected saves you money. Annual maintenance can cut your energy bill by 15 percent. Overall, the price of preventative measures and inspections helps your HVAC system stay alive longer which saves you from a full replacement.

A decent air conditioner should last 15 years if it's taken care of. O'Fallon, IL, business and homeowners can prevent any unexpected failures by scheduling maintenance checks at least once a year. Our AC inspection and repair technicians are just a phone call away.
