Preventative Maintenance

At Cornerstone Mechanical, our experts are here to ensure your home’s heating and cooling equipment is operating at peak efficiency all year long. Well maintained HVAC systems experience fewer system and parts failures and run more efficiently, saving you money over the life of your equipment. You're welcome to schedule a maintenance service (tune-up) as needed or we offer a convenient preventive maintenance plan. This plan includes biannual pre-season maintenance visits which help to protect your comfort system from potential system or parts failures during times of heavy usage. 

Repair

When your home’s heating and cooling system is not running at peak performance, or worse yet, experiences a system failure, it can be a frustrating experience. How much are repairs going to cost? How long until your system is back up and running? At Cornerstone Mechanical, your Comfort is our Mission. This means that we understand your concern regarding the time and cost associated with your system’s repairs. This is why we guarantee that we will explain your options for repair in easy to understand terms.

Ductless Systems

Renovating your home often means adding another heating & cooling system so you can fully enjoy your new space. Maybe you'd like an extra bedroom in the attic or your finished basement would get a lot more use if it was heated & cooled like the rest of your home? Then this may be the option you're looking for. Ductless air-conditioning and heat pump systems (also called mini-splits) have three main components: an indoor unit, outdoor unit, and remote controller. Installation is as simple as mounting the indoor and outdoor units, connecting the refrigerant lines, and making a few electrical connections. Contact us today and we'll take a look at your space and design a solution that suits your needs!

Indoor Air Quality

An HVAC system controls much more than just temperature. It can also improve indoor air quality in your home which leads to a higher level of comfort, cleanliness, and health. Options include humidifiers, air purifiers, and whole-house filtration systems. Concerned about your air quality? Call today to find out how our indoor air quality solutions can help you breathe easier!
