We’ve become the area’s most trusted HVAC contractors because we’re honest and open with our clients. We don’t sell them things they don’t need, say we’ll be there when we won’t, or leave a job before it’s completely finished and the client is satisfied. We’re trained and certified HVAC specialists with the solutions clients need. When heating or cooling systems are on the fritz, know exactly who to call for the skillful repair or installation that will fix your problem for good.

  HVAC systems are critical to any building, not just for personal comfort. Having adequate airflow and venting is essential for residents’ health and the building’s energy efficiency.

When you’re dealing with an HVAC issue, we’ll schedule an appointment for us to inspect your system and discuss your best options with you.

Frequently Asked Questions

Need more information? Our most common questions are answered below.

  • What Is a General Contractor?

    A general contractor oversees construction or renovation projects, including hiring and managing individual subcontractors. Property-owning clients will often hire and deal only with the general contractor, who in turn supervises all other departments such as electrical, plumbing, landscaping, flooring, carpentry, masonry, etc.

  • What Does a Michael O'Leary Design & Build Inc General Contractor Do?

    After hiring all the subcontractors, a general contractor will manage scheduling and payment for all workers. They supply all materials, tools, machinery, and often a work crew of their own for less specialized aspects of the job. They monitor cash flow and safety for the duration.

  • How Does a General Contractor Prepare an Estimate?

     A general contractor will use specialized software to compile a detailed cost estimate for a project based on expected labor costs, materials, equipment, and timeline. If you have an idea of what you want, preparing a list of the expenses for, say, cabinetry or flooring will help expedite the time of estimate preparation.

  • Are You Insured?

    Yes! It’s in our and the client’s best interest to be insured, so of course, we are. Our coverage protects all parties in the unfortunate incident of a worksite accident causing property damage or human injury.

  • Are You Licensed?

    Yes, we’re construction industry professionals with all necessary trade training, safety certifications, and licenses under our belts. Protect yourself by always hiring a licensed, insured general contractor, or be prepared to pay out of pocket for unexpected incidents, including years of workers’ compensation should an injury be sustained.

  • Does My Remodeling Job Need a Permit?

    We recommend erring on the side of caution and getting a permit for any remodeling or renovation project. A permit proves your upgrade was legitimate, correctly done, and up to code. As these things can take time, it’s important to start researching requirements early. Without a permit, you risk being fined and shut down at any point in the construction process. Re-coordinating schedules could delay the project’s end by months, so it’s better to be safe than sorry.

  • At What Point in the Planning Should I Hire a General Contractor?

    The sooner, the better. You want to ensure you find a general contractor you feel comfortable with, who shows you past work that appeals to you and is knowledgeable and easy to reach. A reliable, reputable general contractor will likely have several projects on the go, so you want to book them early to secure the time you hope to spend building. For example, you’ll want to start looking for referrals in the previous fall for a spring renovation. The good news is, if you’re here, you’ve already found a reliable, reputable general contractor at Michael O'Leary Design & Build Inc.

  • How Do I Find Out How Much My Project Will Cost?

    As a rule of thumb, once you have your estimate in hand, there’s usually a possibility of unexpected costs being added to the projected total. A project rarely runs without surprise situations that have to be handled—perhaps at an additional cost—before the crew can get back on course.

  • How Do I Contact you?
