AC Installation and Repair

Having an AC problem at your business? Call (516) 671-3232 for professional repair and replacement service.

It’s important to properly maintain your AC unit to make sure it continues to provide comfort during the warmest months of the year. If you are experiencing trouble with your unit, our highly trained HVAC technicians at Maccarone Plumbing will help you detect the exact cause of your unit’s failure so that proper repairs (or even a replacement) can be performed. We serve commercial sites across Long Island and Five Boroughs.

When Should You Repair Your AC?

Below are common problems that indicate a repair is in order.

Refrigerant leaks: We will help you fix any leak, add the correct amount refrigerant, and then do testing on the repairs to ensure that your AC is in working order before we leave.

Improper maintenance: Allowing AC coils and filters to stay dirty for too long will often lead to the fans or compressor failing prematurely.


Electronic control failure: With over-sized AC systems, fans and compressor controls have a tendency to wear out more quickly than the smaller models. The corrosion of terminals and wiring are other common electrical problems.

Sensor issues: In some cases, sensors can unknowingly get knocked out of place, causing the AC to run continuously or behave strangely.


Clogs: Air conditioners will fail to drain if they are not mounted properly.

What are Signs You Need a Replacement?

No matter how diligent you are at maintaining your AC unit, it will eventually break down from age and need to be replaced. Below are signs that your current unit needs to be removed and replaced with a new one.


Frequent repairs: If you are calling to have professional repairs performed on your AC unit as often as once a month, over the course of several months, you will be better served installing a brand new unit. A new unit is more energy efficient and cost effective than having frequent repairs done.


Higher energy bill: If your energy bill increases even though your usage remains the same, your AC unit’s power usage has become less efficient than it once was. The ideal solution is to replace your current unit with a more energy efficient model to keep future energy costs down.


Your AC is over 10 years old: Again, even with the best maintenance, eventually your AC will need to be replaced, especially if it’s more than 10 years old.


Unusual sounds: If you hear gurgling or clanking sounds, this means there is a problem with your AC’s internal parts. If the noises persist after repairs are made, it’s time to have a new unit installed.

How Can You Avoid AC Problems?

You won’t want to put off AC maintenance until the summer starts. We can prepare your business for the warmest months with annual maintenance inspections to determine if any repairs are needed. In the meantime, here are simple maintenance tips to help you care for your AC year-round:

  • Check evaporators, condenser, air filter, and air ducts for dirt, and clean them if needed.

  • Check the fan belt and motor for blockages.

  • If the condenser turns on and off on its own, remove all dirt and debris from it.


Stay cool this summer! Call us today at (516) 671-323 to get started on your AC service.
