AC Replacement

Our Expert Air Conditioning Replacement Services

Even air conditioning units that are properly maintained will eventually need to be replaced due to mechanical failures, reduced performance, or lack of efficiency. Repair costs are piling up? Looking to take advantage of the latest energy-efficient technology? Our air conditioning services can make the removal and installation process simple and stress-free. 

Exxel Mechanical Services is a trusted HVAC company serving Central Maryland from our home base in Mount Airy, MD. We are here to troubleshoot issues with your air conditioning system and recommend a solid path forward, whether that’s repair or replacement.

What Are the Signs I Need Air Conditioning Replacement?

Some air conditioning issues can be fixed with quick repairs. However, once the cost of repairs exceeds 50% of the cost of a new unit, it’s better to replace your AC equipment instead. Our experts can help identify signs that you might need a new unit. They’ll also assess your needs to select the perfect new air conditioner for your home.

Some of the signs that you might need a new Air Conditioning System:

  • An air conditioner that is over 15 years old
  • Blowing out warm air instead of cool air
  • Strange banging, clicking, squealing, hissing, or screeching sounds coming from the unit
  • Odd or unpleasant smells coming from the HVAC system
  • Limited or non-existent airflow
  • Needing repairs regularly, or having multiple components replaced in the past few months
  • High humidity levels
  • Moisture present around the AC unit
  • Sudden spikes in your utility costs compared to past years

Regardless of what you are experiencing, our expert HVAC technicians can come out for a service call to make professional recommendations regarding repair or replacement. If you choose to have repairs performed, we have fully stocked trucks so that we can fix many common issues on the spot.

How Can A New Air Conditioning System Improve My Home?

Installing a new air conditioning system into your home brings a load of benefits beyond just keeping you cool during the hot and sticky Maryland summer months. 

Here’s how a new AC system can enhance your home:

  • Improved Comfort:  A new AC system ensures consistent cooling throughout your home, eliminating hot spots and ensuring everyone stays comfortable no matter the temperature outside.
  • Enhanced Indoor Air Quality: Modern AC units come with advanced filtration systems. These systems help remove dust, pollen, allergens, and other airborne particles from your indoor air. That means cleaner and healthier air for you and your family
  • Energy Efficiency: Newer air conditioning systems are designed to be more energy-efficient, helping you save on your monthly bills. They use advanced technology and features like variable-speed motors and programmable thermostats to optimize energy usage while maintaining comfort.
  • Reduced Environmental Impact: Energy-efficient AC systems use less electricity, shrinking your carbon footprint and contributing to a healthier environment. 
  • Enhanced Home Value: Installing a new AC system can increase the value of your home. Potential buyers often pay more for homes with modern, efficient HVAC systems, making it a worthwhile investment for your future.
  • Quieter Operation: Older AC units can be noisy and disruptive, especially as they age. Newer models are designed for quieter operation, ensuring a peaceful environment without the constant hum of the air conditioner.

Quality HVAC services like AC installation can benefit you and your home in so many ways, the investment can be well worth it! Especially when your current AC is getting older and less efficient, or you find yourself calling for emergency services more often than you’d like.
