Furnace Installation You Can Trust

The foundation of a professional furnace installation is determining the correct size needed for your home. A furnace that's over- or undersized is inefficient, costs more to operate, wears out prematurely, and won't keep your family warm. Many of our technicians are experts at evaluating the factors that affect your comfort and calculating the correct size. Here are a few other reasons why Custom Mechanical is a good choice for your furnace installation:

  • Free estimates
  • Clear explanations of options and efficiency ratings
  • Respect for your home during installation

When It's Time for Furnace Replacement

Knowing when to replace your furnace isn't an exact science. At Custom Mechanical, we understand that deciding to replace your furnace frequently hinges more on subjective criteria than objective. If you experience a complete system shutdown, that's straightforward: you need furnace replacement.

Other criteria, such as your heater's age, aren't always so cut-and-dried. Is a 12-year-old furnace less efficient than a 10-year-old one? The frequency of repairs is increasing, but they're relatively inexpensive repairs. How much is too much to put into a furnace before you upgrade? We provide expert guidance that answers these confusing questions and puts you on track to make an informed decision. Once you've decided it's time for furnace replacement, we'll help you choose the one that fits your needs and install it quickly and professionally.

We earned our stellar reputation by delivering excellent products, outstanding service, and professional heating installation. So whether you're looking to replace an aging furnace or install heating equipment in new construction, Custom Mechanical is the heating company you can trust in Delmarva.


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.
