Air Conditioning Installation & Replacement in MD, DC, NOVA, NJ, PA & DE

When it’s time to replace your air conditioner, our team will help you find the right make and model for your needs. If you’re thinking about installing a new AC system, it’s important to consider:

  • The size of your home: The square footage and layout determine how many British Thermal Units (BTUs) are required to cool your home.
  • Energy efficiency ratings: Choose a system with a high Seasonal Energy Efficiency Ratio (SEER) to enjoy lower energy bills and eco-friendly operation.
  • Budget: Choose a system with the best features for your budget. We also offer financing options on approved credit to help you afford your new unit.

We understand that every home is different, and we work to bring customized cooling solutions to each customer.

Alternative HVAC Systems We Install

In addition to traditional AC units, we also offer ductless mini-splits and heat pumps. These systems provide efficient cooling and heating from a single unit.

Mini-splits are ideal for homes without conventional ductwork, and heat pumps are the top choice for eco-friendly home comfort.

Frequently Asked Questions

How do you troubleshoot your air conditioner?

Before calling for service, homeowners can check for common issues like improper thermostat settings, tripped circuit breakers, or dirty air filters.

What should I do while waiting for emergency AC repair?

Stay hydrated, use fans, and close curtains to keep cool. Avoid using heat-generating appliances and consider going to a cooler location if the indoor temperature rises significantly.

Will an oversized air conditioner keep my home cooler?

No. An oversized unit can cause frequent cycling, increased energy usage, and uneven cooling. It’s important to choose an AC unit that’s properly sized for your home.

What are the benefits of AC replacement?

Replacing an old or inefficient air conditioner can lead to improved comfort, lower energy bills, and fewer repairs.

What happens if I don’t schedule AC maintenance?

While AC maintenance may not seem important, neglecting it can lead to reduced energy efficiency, higher energy costs, and a shorter life span for your air conditioner.

What AC maintenance tasks can you do yourself?

Homeowners can regularly replace air filters, clean debris around the unit, keep vents clear, and run a test cycle to check for unusual sounds or smells.
