Air Conditioning Installation & Replacement

You can expect your air conditioner to last approximately 15 years with proper maintenance. If your AC unit is past its prime, turn to our experts at Len The Plumber Heating & Air for an air conditioning replacement.

We offer AC installation and replacement throughout the Millersville area, and the process starts with calculating your cooling requirements. When you are selecting your new air conditioner, consider the following factors:

  • Size: A system that is too small won’t keep you cool enough, and a system that’s too large will drive up your utility bills. An accurate load calculation will ensure your system operates optimally.
  • Efficiency: New AC systems start at 15 SEER but can exceed 20 SEER. The more efficient the system, the more you will pay upfront, but your monthly electrical costs will be lower for the life of the unit.
  • Features: For the greatest comfort and efficiency, consider features like dual-stage cooling, variable-speed blowers, and smart thermostats.

Alternative Cooling Systems We Install

In addition to central air conditioners, we also install ductless AC units and heat pumps.

  • Ductless mini-splits require no ductwork and deliver precise temperature control with zoned comfort.
  • Heat pumps provide great energy efficiency for heating and cooling throughout your home.

Air Conditioning Maintenance

Routine AC maintenance is the key to maximizing the performance, reliability, and longevity of your system.

At Len The Plumber Heating & Air, we recognize the importance of preventative air conditioning maintenance. We recommend a service visit at least once a year, preferably in the spring, so that you know your air conditioner will be ready for the cooling season.

During the visit, our team will perform all the maintenance tasks required by your system, such as:

  • Inspecting the air filter
  • Inspecting the electrical connections
  • Checking refrigerant pressure
  • Cleaning coils
  • And more
