When your cooling system fails, contact the professionals at A+ Derr to request emergency AC services today!

24/7 Air Conditioning Repair & Replacement

Day or night, holiday or weekend, our team is available throughout the summer to respond to your cooling emergencies. When your system requires service, we will promptly dispatch a technician to your home, condo, or apartment to assess the malfunction’s cause and repair your system.

Of course, some problems simply can’t be repaired. When you have an older system, repairs won’t restore functionality or safety, and the cost of repairs exceeds more than 50% of the replacement cost, we will help you select a suitable replacement. We offer a full range of high-quality systems from Lennox and will perform the thorough load calculations, site preparation, and installation services required to improve your comfort with a new air conditioner, heat pump, or ductless system.

Systems We Offer Emergency Services For

Our technicians have the advanced skills and up-to-date expertise to service various systems. We adhere to the highest quality standards and will provide durable repairs you can depend on.

  • Central AC units: We can seal refrigerant leaks, replace damaged fan motors, clear dirty coils, replace faulty thermostats, and more.
  • Ductless ACs: Our team can resolve refrigerant leaks, correct electrical malfunctions, replace faulty sensors, and more.
  • Heat pumps: Our technicians can seal refrigerant leaks, replace reversing valves, thaw frozen outdoor units, replace defective capacitors, and more.

Signs You Need Emergency AC Services

There are many signs that your AC system requires repairs. Some are subtle, and others are more obvious. If you detect any of the following, we recommend scheduling service without delay:

  • Diminished airflow: This can be caused by a faulty blower motor, clogged ducts, or clogged air filters.
  • Short-cycling: This can be caused by faulty wiring, electrical shorts, or a system that is improperly sized for the home.
  • Leaks: Blown debris, pests, accidents, and age can cause drain pans to clog or refrigerant lines to leak.
  • Tripped breaker: This is often caused by improper sizing or internal electrical faults.
  • Frozen coils: Frozen coils can be due to dirt accumulation on the coils, lack of refrigerant, and other issues.

Frequently Asked Questions

We advise against DIY repairs. Not only does it risk potential electrical or toxic exposure, but it can also negate any manufacturer warranty coverage.

With proper care and maintenance, central air conditioners tend to last 10 to 15 years, heat pumps 20 to 25 years, and ductless mini-splits 15 to 20 years.

We strongly advise all homeowners to service their air conditioning systems regularly and recommend scheduling preventative maintenance in the spring before the hot weather.

Jake came and did my spring service yesterday. Their service is very professional, they are always out to get the best deals for anything I may need. I purchased new units from them a couple years ago, and the savings has been so noticeable.
