    Wanted to share how happy I was with John Reece. I was very happy with Hoffmann overall and don’t have anything bad to say about Hoffmann Brothers. John did excellent work and just felt his managers need to know what a great employee they have. We were also happy that he was on-time and very informative.

Contact Hoffmann Brothers

It’s important not to take chances with the hot St Louis summer heat. This seems obvious, but less so when it comes to the AC units we rely on each year. When AC maintenance gets forgotten, you could be looking at a breakdown, replacement and new AC installation that could have been avoided. It is recommended that you have a licensed air conditioning contractor perform the home AC maintenance services on your system each year before the heat of summer arrives. At Hoffmann Brothers, our trained central air conditioner maintenance contractors will work through an important AC maintenance checklist and always put safety first.

Don’t skip your AC unit maintenance or struggle through a hot St Louis summer before making your call to Hoffmann Brothers for air conditioning preventive maintenance.

Common Air Conditioning FAQs

What We Do During a Routine AC Maintenance Visit?

At Hoffmann Brothers we check refrigerant levels, inspect the unit for hail damage, mower or debris damage and inspect cabinet for missing screws, broken supports, level of unit. We will confirm that the safety controls are functioning properly and inspect the condenser fan grill for broken mounts, missing screws, or other damage. We correctly charge your AC unit after winter or a period non-use and check the filter in the furnace. We will also inspect the condenser fan motor wiring for loose or damaged wiring and inspect ductwork for sealing issues. Last, we will secure electrical connections and thoroughly clean the outdoor unit by removing debris, blockage and accumulations

Is It Necessary To Service My Air Conditioner Every Year?

Hoffmann Brothers Heating & Air Conditioning recommends that your air conditioner be serviced at least once a year. Getting an annual tune-up will keep your AC running at its highest efficiency while lowering your energy bills and chances for system breakdowns in the future.

What Maintenance Does My Air Conditioner Need?

Several components of your air conditioner require routine maintenance. The U.S. Department of Energy recommends that you replace or clean your AC’s filter at least monthly during the cooling season; this can reduce its energy consumption by 15%. The DOE also suggests annual cleaning of your AC’s coils, which collect dirt over time.
