Thomas came through in a pinch when our air went out on a weekend. Even with the emergency fee, his rates are very reasonable. It was a simple part replacement rather than the whole unit, which we thought might be necessary. I can’t say enough good things about Thomas. We will certainly use him again!

Tom Hoffman saves the day AGAIN! We’ve used Tom Hoffman for heating and cooling services for many years and they always come through when we need them. Once again , Tom came very quickly and fixed our broken AC on a Saturday! He always does great work for a fair price .

It was the end of Spring coming into the Summer cooling season and our air conditioner that was about 20 years old stopped working. We were new to the area and didn’t know any of the HVAC folks so had to get several estimates.Our estimates ranged from inexpensive but incomplete to really expensive and way more than we needed, and many of the salesman were telling me things that I later found were just not true.Thomas Hoffmann gave an estimate that was fair and answered the barrage of questions that I asked of him.The day of the installation, the team arrived on time, early in fact, install the air conditioner/water heater/air filter and air cleaner, the installation looked great and to my delight they left the area in a cleaner condition than when they found it.Recently, we’ve had other trades come out and one asked me if they were turning the wrench in the right direction to loosen a nut and another needed access to my attic from inside the house, leaving greasy marks on the access panel, so, having a team like Thomas Hoffman Air Conditioning and Heating LLC accomplished what they did in one day with competence and professionalism gives us the confidence that the job is done right. Because of this, we’ve asked Thomas Hoffman Air Conditioning and Heating LLC to do a similar size job at another property.

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.
