What to Expect with a New AC Installation

Installing a new air conditioner is an important investment, and we make the process simple, stress-free, and transparent. Landry Mechanical’s expert team walks you through each stage to ensure you get the right system and the best results.

Personalized System Recommendations

We start with a home assessment to understand your cooling needs. Our technicians consider factors like square footage, insulation, and existing ductwork to recommend the best air conditioning system for comfort and efficiency.

Energy-Efficient Equipment Options

We install high-performance systems from trusted brands that help reduce energy costs and deliver consistent cooling. Whether you’re upgrading an outdated system or installing central air for the first time, we’ll help you find an option that fits your goals and budget.

Professional Installation Process

Every new AC system install is completed to manufacturer standards and tested for accuracy, safety, and airflow. Our technicians double-check refrigerant levels, thermostat calibration, and electrical connections before we leave your home.

Old System Removal and Cleanup

We remove your old unit responsibly and ensure your new installation area is clean, organized, and ready for immediate use. Our team treats every home with care and leaves your space better than we found it.

Post-Installation Testing and Walkthrough

Once the installation is complete, we’ll review the new system with you, explain key features, and answer any questions. We also perform a final performance test to confirm that your new AC is cooling efficiently and evenly throughout your home.

When Is It Time to Get a New AC?

If your air conditioner is struggling to keep up with Millbury’s summer heat, it might be time to consider a replacement. Frequent repairs, weak airflow, rising energy bills, or uneven cooling throughout your home are all signs your system may be nearing the end of its lifespan. Most AC units last around 10 to 15 years, and upgrading to a new AC system installcan improve efficiency, reduce energy costs, and keep your home consistently comfortable for years to come.

Was 3 1/2 hours late for an appointment I made a month ago. They couldn’t even get my name right. No apologies or even an idea when they would be here. Very inconvenient.

Corey Menard is a STELLAR human being as well as an EXPERT HVAC technician! He cheerfully and swiftly diagnosed an in-wall heating pipe burst, repaired it, and added a much-needed shut-off valve for one of my (three) heating zones. My English language dictionary does NOT contain the words I need to express my gratitude toward him, or express my gratitude to Landry for sending Corey to my home on Wednesday 02/11/2026. Thank Corey, thank you, and thank Corey!
