Of the bids that we got, Simply Mechanical was the most knowledgeable, honest and reasonably priced. Options were presented and we decided to replace our furnace. A temporary fix was done until the replacement could be scheduled. Our new furnace got us through the cold snap!

Frequently Asked Questions

What should I consider when choosing an AC unit for installation?
Think about your home’s size, energy goals, budget, and features like quiet operation or smart tech. We’ll help you find the right system for your lifestyle and cooling needs.

Most installations take 4 to 8 hours. If you’re replacing an old unit, it might take a little longer depending on the setup. We’ll let you know exactly what to expect upfront.

Usually, no significant changes are needed. If you’re upgrading to a more efficient system, we might suggest minor adjustments to optimize performance, and we’ll walk you through those before we begin.

It depends on the size and type of unit and your home’s layout. We’ll give you a detailed quote tailored to your needs and budget.

Schedule regular maintenance, change filters as needed, and keep the outdoor unit debris-free. Using a programmable thermostat also helps you save energy while staying cool.
