Lancaster's Leading A/C Replacement Contractors

Over the last decade, the average central air conditioner has become much more efficient and reliable, thanks to the latest advances in technology. If your home has an older A/C unit that is nearing the end of its expected lifespan—typically about 10 or 15 years—it’s time to consider a replacement. Operating and repair costs may soon make the replacement cost look more appealing, especially when the greater efficiency is factored in.


When you are ready for a new A/C unit, look no further than our team at The Witmer Company. We offer complete air conditioning replacement, repair, and maintenance services, and we have extensive experience with all common heating and cooling equipment. Our dedicated professionals have been serving homeowners in Lancaster County since 1941.

When to Consider an A/C Replacement

A new central air conditioner is a significant investment, but if your current system is older or has serious problems, it may be worth the expense and inconvenience to replace it. You should consider a new A/C system if your current unit:


  • Is over 10 or 15 years old
  • Does not cool or dehumidify effectively
  • Is costly to operate compared to new models
  • Requires frequent maintenance and repairs to remain operational
  • Has major problems like a damaged condenser or failing compressor

The Benefits of Replacing Your A/C Unit

Installing a new AC system can have many benefits for homeowners, including:


  • Greater efficiency. Older air conditioners often had SEER ratings of far less than 13, while today’s models range from 13 to over 20 SEER, which can reduce cooling costs significantly.
  • Higher reliability. With a new A/C system using the latest manufacturing standards, you will not have to worry as much about breakdowns or failures, as long as it is well maintained.
  • Improved comfort. With new technologies like dual-stage compressors, variable-speed blower motors and zoning systems, today’s air conditioners cool more effectively, efficiently and quietly.


At The Witmer Company, we can help you select the appropriate system for your needs and keep you informed throughout the air conditioner installation process—from load calculation and sizing to system design and installation. Contact us today to schedule a quote and we'll have one for you within 24 hours.

"I had The Whitmer Company install and service my heat pump now for 13 years and you could not ask for a better company. Technicians are always very friendly and professional wearing booties every time they enter your house. I would highly recommend The Whitmer Company to anybody looking for an HVAC company."
