Packaged HVAC Unit Installation

We offer all-in-one HVAC units for both heating and air conditioning. For residential packaged units, we begin with a home inspection and an energy efficiency evaluation. These steps are essential to picking the right size HVAC setup and choosing an optimal place to install the different parts.

You don’t want a system that’s too large because it will cycle on and off rapidly due to short cooling cycles. This can lead to extreme wear on the equipment, which results in premature breakdowns and replacements. A system that’s too small will cause just as many problems. It will struggle to meet your household’s cooling demands, causing it to run constantly and experience overheating. With a professional installation performed by A+ Derr, you don’t have to worry about issues with proper sizing. We have advanced diagnostic tools and load calculation software to ensure we choose the right setup with the correct capacity.

After the installation process is complete, we’ll walk you through using your new HVAC unit. The functionality of all-in-one systems is very similar to regular setups. You’ll simply adjust the connected thermostats to the temperature you want and then let the system take over. We’ll also walk you through how to maintain your new packaged HVAC. Just like any other setup, packaged units need professional maintenance at least once a year.

Should Every Home Have a Packaged HVAC System?

The great thing about packaged HVAC units is that you don’t have to deal with separate indoor and outdoor components. Instead, you have one self-contained system housed in a single cabinet. This simplifies installation, saves space, and helps cut down on maintenance and energy waste. However, not every home is suitable for a packaged HVAC setup. That’s why our careful assessment process is so important for making the right recommendation. 

The top advantages of packaged HVAC units include:

  • Compact design saves space
  • Efficient year-round comfort
  • Easier maintenance and access
  • Quieter outdoor unit operation
  • Streamlined rooftop installation process

Jake came and did my spring service yesterday. Their service is very professional, they are always out to get the best deals for anything I may need. I purchased new units from them a couple years ago, and the savings has been so noticeable.
