    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.

Common AC Repair FAQs

Why is my AC not cooling?

There are many common reasons that your air conditioner is not cooling- the most popular being refrigerant leaks, inadequate maintenance, electric control failure, sensor problems and drainage problems.

What should I do if the fan on my outside unit (condenser) is not working?

First, make sure thermostat is on and check for a tripped breaker. You will want to clean or replace any dirty air filters and check to make sure there is no debris blocking the fan blades. If the problem persists, call a professional HVAC technician to help further diagnose the issue.

How can I make my air conditioner last longer?

The best ways to prolong the life of you air conditioning unit are to complete annual maintenance and change your air filter regularly.

How long do air conditioning units typically last?

The average life span of an AC unit is 10 years

How do I know if my unit is efficient?

Seasonal Energy Efficiency Ratio or SEER Rating is the efficiency rating of the air conditioner. The higher the SEER the more efficient the air conditioner and the lower your monthly bill will be. SEER ratings of older AC units are typically very low. Air conditioners wear out over time and have older technology. It is typical to find old AC units with SEER ratings of 6-10 SEER. By upgrading and replacing your air conditioner, our customers typically see a large reduction in utility costs as well.

What should I consider when purchasing an AC unit?

The main factors to consider when purchasing an AC unit are time, cost, and efficiency. Hoffmann Brothers also recommends you also consider the following: humidity extractor, size of the unit, environmentally considerate coolant, minimum noise, and energy efficiency
