5 Benefits of Installing Air Conditioning in NY

A new air conditioner can be a great investment for anyone in our area, whether you’re installing a system for the first time or just looking at replacements. A new air conditioner matched to your needs and installed properly allows you to enjoy:

  • Enhanced comfort: A modern air conditioner will keep you consistently cool without freezing you out or leaving your home or business full of hot and cold spots.
  • Reduced humidity: ACs also manage humidity, which isn’t just important to comfort. It’s a factor in health, pests, mold, and other hazards to your property.
  • Improved safety: Don’t be caught flatfooted by a heat wave and find yourself or your family members at risk of heat stroke — keep reliably cool with a new air conditioner.
  • Lower energy bills: Modern AC technology is substantially more efficient than older units, meaning you can maintain the same or greater comfort while spending far less each month.
  • Increased value: Old HVAC equipment can be a serious anchor around the neck of any property — make sure yours has a system to match its needs.

Switch from Window Units to Ductless AC

Many properties in New York still don’t have central AC, even as temperatures increase. Even if you don’t want to run ducts or don’t have space for them, there’s a much better option than window units: ductless AC. With a single exterior unit and one or more interior units connected via refrigerant lines, these systems allow perfect climate control without needing bulky ductwork or a window.

Where window units are frequently inefficient due to the leakiness of adjacent windows and can struggle to produce proper cooling across your home or office, ductless mini-split systems allow for efficient, reliable cooling throughout with as many interior units as you need — you can even keep some rooms cooler and other rooms warmer with a zoned climate control setup.

Central air conditioning, properly maintained and repaired as needed, usually lasts between 15 and 20 years. Many systems fall short of this or show their age and inefficiency in the form of higher energy bills or reduced comfort.

The decision to repair or replace your system usually comes down to its age and the cost of the repair; the older your system, the bigger the repair, or the more frequently your system has needed service recently, the more likely it is that replacing your system is the wiser investment. Older systems can only buy so much time, and it’ll be full of inefficiency, discomfort, and additional repairs.
