From SEER ratings to capacity to refrigerants, Custom Mechanical knows the ins and outs of air conditioning installation. Along with free estimates and a satisfaction guarantee, we offer decades of experience keeping Delmarva residents refreshed when temperatures begin to climb.
Correct Sizing for Your Air Conditioning Installation
Delmarva homes come in various sizes and designs and have diverse energy demands. A cooling system that is undersized for your home's characteristics has to work overtime to counteract the heat and humidity. On the other hand, with an oversized design, you pay more in equipment costs and operational costs because the system constantly cycles off and on without ever completely cooling your home.
Our technicians thoroughly assess your home before recommending a cooling system for your family. We consider factors such as sun and shade, square footage, and insulation values. As a result, you can trust us to find the system that fits your home and budget. Once we do, we install it quickly and professionally.

Signs It’s Time for an AC Replacement or Upgrade
If your cooling system suffers a sudden shutdown, you may suddenly be in the market for a new air conditioner. Our AC maintenance plans can help prevent that worst-case scenario. And if your current unit needs frequent and ever-more-costly repairs, AC replacement is likely in your near future.
There are, however, reasons to consider replacement even if your existing system still functions. Over the years, you might have become accustomed to the back bedroom that never really gets cool or resigned to lowering the thermostat to save on electric bills. A new system is typically more efficient than even a 10-year-old unit; the cost savings can add up quickly, to say nothing of the enhanced comfort throughout your home. Regardless of why you need AC replacement, our technicians at Custom Mechanical will walk you through the process and help you find the system that matches your family's needs.
Why suffer through another hot summer? When you let Custom Mechanical handle your air conditioning installation, you'll get improved comfort and lower energy bills in your home. So give us a call today. Our services are available to homeowners in Frankford, Rehoboth, Bethany Beach, Millsboro, Ocean View, Georgetown, DE, and the surrounding beach communities in Delaware and Maryland.

How to Select the Right Contractor for Your Air Conditioning Needs
Finding the right air conditioning service company is essential to avoid costly installation errors. When evaluating contractors in the air conditioning industry:
- Read air conditioner installation reviews to verify consistent customer satisfaction and quality customer service.
- Ensure the company employs a factory-trained air conditioning service team with extensive hands-on installation experience.
- Look for comprehensive warranties and ongoing installation support, including routine air conditioning maintenance plans.
- Avoid contractors pushing oversized units; proper sizing matters far more than replacing outdated window air conditioners with mismatched central setups.

FAQs About AC Installation Service
What size HVAC equipment is right for my home?
Many factors affect the sizing and specifications of your system, including square footage, insulation, window surface and configuration, geographic location of your home, and duct sizing and arrangement. A technician from Custom Mechanical can perform an in-home load analysis to determine which equipment combinations will perfectly suit your home and your family's needs. Depending on the construction of your home, one (1) ton of air conditioning can cool anywhere from 300 to 800 square feet. You can ensure that the system you purchase is the right size and not smaller or larger than you require, by having your heating and cooling needs evaluated by a licensed professional.
What is the life expectancy of my unit?
HVAC systems last an average of 10 years. However, for your equipment, it may differ. Variables that affect life expectancy include the type of system, climate and the regularity of routine maintenance.
