Air Conditioning Installation and Replacement

If your air conditioner has reached the point where repairs no longer do the job or your home’s energy efficiency is at an all-time low, you may need a new system. When your Newark, DE, home is ready for an air conditioning replacement, our Joseph Frederick & Sons professionals will install your cooling system without delay.

How do you know if you need a replacement AC unit? Here are some of the most common issues. Your unit is:

  • Approaching the end of its life span, usually between 15 and 20 years
    Efficiency decreases as your system gets closer to the end of its life. You want to act proactively to plan what your replacement purchase will be instead of acting reactively when your system unexpectedly quits. This can save you money.
  • Experiencing more and more repairs
    Similar to when your car requires more and more repairs, there comes a time for evaluation. Are you spending more in repairs than it would cost to invest in a new system? If the answer is yes, call and talk to one of our knowledgeable team members to discuss your options.
  • Showing signs of running inefficiently
    How can you tell if your air conditioner is running inefficiently? A good indication is if your energy bills are increasing and your utility company’s rates remain steady.
    This typically demonstrates it’s taking longer for your heating, ventilation, and air conditioning (HVAC) system to cool down your Delaware home to your preferred comfort level. Your system is running longer and using more energy than it should in this case—an increase in energy costs.

If you notice any of these signs, or if you suspect another reason for needing an air conditioning replacement, talk to one of our Joseph Frederick & Sons team members. We will design a system best matched for your comfort needs and budget. Our experts are always here to help you.

We also offer several financing options to help if this is a concern. Contact us to discuss how our team can guide you through our process.

Air Conditioning Repair

When your AC is not working on the hottest of days in Delaware can be exasperating. Whenever you need air conditioner repair, let our heating and cooling experts quickly remedy it for you.

There are several ways your AC unit can stop working in its normal capacity. A few symptoms are:

  • Hearing an unusual noise
  • Smelling an unusual odor like burning
  • Feeling warm air coming from your vents
  • Noticing your air conditioner is frozen
  • Leaking water

These symptoms mean you have an issue. Ignoring problems usually only makes them bigger and more costly. Our recommendation is to have one of our Joseph Frederick & Sons team members promptly diagnose and provide you with professional air conditioning repair.

When you do need our professionals to make a repair, you can count on it staying repaired. We do it right the first time—and only use the highest quality parts and materials when working on your cooling system. Our experts are always here for you.

“Lucas serviced our air conditioner and heater as well. He was on time, professional, friendly, and easy to communicate with. He was most efficient and replaced a dual capacitor on our air conditioner, which he had with him on his truck. After his explanation of membership, we agreed to join, which saved us money on service and parts. We hope to see him again when the time comes for future service. He is an outstanding employee.”
