Amazing service from Thomas Hoffmann! They made space in their schedule to come out the next day to fix our air conditioner. They were on time, honest and fixed the problem on the spot. Thank you!

Fast efficient service. Both of the gentlemen that came to my home were very help and informative not to mention polite. It’s difficult to get service advisers to appear at your home when scheduled most times they’re late or don’t show up at all. Not an issue with this team on time, clear diagnosis, quick repair. I would definitely use Thomas Hoffmann Air Conditioning again. I recommend them highly.

I’ve been using “THOMAS Hoffmann Airconditioning and Heating” for years now. We have a 30 +\- year old system that works perfectly for us. Although we’ve not had to use it yet, it is comforting to know they offer a 24 hour on call service. I really appreciate that the technicians don’t try to upsell us on anything. They’re a very professional, knowledgeable, and courteous, local-family owned and operated business. I’ve also found their pricing to be very fair and by”fair” I don’t mean “cheap” but reasonable… especially for the quality of service provided by THOMAS Hoffmann HVAC. I love supporting smaller family owned business and this one is top-notch! Thank you guys!

Thank you Thomas Hoffman Air Conditioning for doing a great of repairing our HVAC system that was damaged during a power outage. You installed our new HVAC system late last year and promptly responded to our call for repair after a power surge impacted our subdivision.

I called on December 25th at midnight and started leaving a message and Thomas Hoffman the owner called me back almost immediately. He said he would come out the next morning between 8:00 and 10:00 am snd he was promptly on time. He fixed my problem and while he was there I decided to get an estimate for a new furnace and air conditioning unit. The price was very reasonable and the installers one of them being his son were both very professional very courteous, polite, arrived on time and finished the same day. I enjoy knowing that I now have the support of Thomas Hoffman heating and air conditioning along with the peace of mind that comes with owning a Trane. Nothing stops a Trane.

Air Conditioner Repair Services

Whether your cooling system is new or old, Thomas Hoffmann Air Conditioning & Heating can quickly restore your home’s comfort level. With over 30 years of experience, Thomas Hoffmann Air Conditioning & Heating has solved everything from minor calibration issues to complete system failure.

Almost every homeowner has experienced some issue with their air conditioner. When you experience any decrease in comfort, strange noises or smells from your unit, rising energy costs, or leakage around your system, it’s time to call the experts. Unfortunately, air conditioners don’t fix themselves. If you procrastinate, the problem will likely worsen and be more expensive. When one component malfunctions, it strains the entire system, leading to further complications.

Common AC Repairs

If you experience a problem with your AC system, knowing some common causes of AC repairs is good. Below are some of the most common issues AC repair technicians encounter daily throughout the hot summer months. Having a better understanding of these common problems can help you feel more at ease with the air conditioner repair process and better comprehend your AC repair technician’s information.

• Refrigerant leak
• Drainage issues
• Broken compressor fan
• Frozen condenser coils

Refrigerant Leak

Air conditioners contain refrigerant, which allows the unit to run efficiently by releasing heat from the air to cool it. When an AC unit is installed, it is charged with refrigerant. However, a poor charge or a refrigerant leak can cause the refrigerant level to fall below the correct amount. Several signs may indicate that the refrigerant in your system is low. Some of these include:

• Vents are not blowing cool air.
• The temperature you set your thermostat to is never reached.
• Ice on refrigerant lines
• The electric bill is higher than average.
• Hissing or bubbling noise

To fix this issue, your repair technician will first address the leak that caused the problem and then charge your cooling system with the correct amount of refrigerant.

Drainage Issues

A second common issue concerns drainage. An AC system produces condensation, which should flow away from the equipment. However, a clog in the condensate drain lines or drip pan may cause moisture to go back into your air conditioner. When there is excess condensation, indoor humidity levels can rise and hinder your cooling system’s performance. It can also damage other components.

Your technician will inspect the condensate lines and drip pan to fix this issue. They will clear any clogs and may be treated for algae growth to prevent clogs in the future.

Broken Compressor Fan

A broken compressor fan is a third common problem. An air conditioner’s outside unit houses the compressor, fan, and condenser coils. These parts release heat from the air, transferring it from your home. When the fan isn’t working correctly, the heat transfer is hindered. This will prevent your AC from adequately cooling your home and cause the compressor to overheat.

Your technician will diagnose the issue preventing the outdoor fan from working correctly. The fan will be repaired if necessary, and they will inspect the outside unit to see whether the problem has caused further damage to the system.

Frozen Condenser Coils

Frozen condenser coils are the fourth most common issue. These coils are in the outdoor unit; your AC will not run properly if they freeze up. When the air can’t flow through your cooling system, ice can form on the coils. The cause is typically dirty air filters or blocked return air ducts. Low refrigerant could also be the cause, requiring a refrigerant charge.
