Expert Air Conditioning Repair

When it comes to repairing your AC system, count on our team for the job. Our technicians know what to look for and how to get your AC working like new. 

We’ll discuss your AC issues with you before we begin any work. That way, you can better understand what may be going wrong with your system.

Once we diagnose the problem, we’ll discuss your options for repair or, if necessary, replacement. 

Signs You Need AC Repairs

AC problems can creep up at a moment’s notice. It may be time for expert AC repairs if:

  • Your AC emits a burning smell: Your air conditioner should never emit a burning smell for any reason.
  • Your AC doesn’t cool rooms evenly: A quality AC should cool all rooms evenly without issue.
  • Your AC drives up your energy bills: If your energy bills are higher than ever, it may be due to a struggling AC system.
  • Your AC makes odd sounds: Every air conditioner will make sounds, but loud banging or grinding is a sign of damage.

Same-Day AC Repairs

When your air conditioner fails, you need professional technicians to handle the repairs as soon as possible. That’s where we come in.

Donnelly’s Cooling, Heating & Plumbing offers same-day AC repairs in the Greater Philadelphia area. We can discuss your situation and get a technician to your home within a day to resolve the problem.

Why You Shouldn’t Wait to Request AC Repairs

It’s never a good idea to wait around and ignore an air conditioner problem. These issues don’t just go away on their own — you need a pro to fix them. When an air conditioner problem goes unresolved, you can run into many other problems, including:

  • Fire risk
  • Further AC damage
  • More expensive repairs
  • Total air conditioner failure
