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 HVAC services do you provide?
We offer a full range of HVAC services, including installation, replacement, repair, and maintenance for heating, cooling, and indoor air quality systems. Whether you need a quick repair or a brand-new system, our team has you covered.
If your system is over 10–15 years old, needs frequent repairs, struggles to keep your home comfortable, or causes high energy bills, it may be time to consider replacement. For newer systems with isolated issues, repair is often the best choice. Our technicians will guide you with honest recommendations.
We recommend scheduling HVAC maintenance at least once a year — ideally in the spring for cooling and the fall for heating. Regular tune-ups help extend the life of your system, improve efficiency, and prevent costly breakdowns.
Upgrading to a modern HVAC system can lower energy bills, improve indoor air quality, provide more consistent comfort, and reduce the risk of emergency repairs. New systems are also quieter and often come with advanced features like smart thermostats.
Yes. All of our work is backed by strong warranties. You can have peace of mind knowing your investment is protected.
