We'd be happy to provide a quote on a new Trane system, or installation of another brand that you already own.
Our service area includes Macomb and Oakland County where we provide complete heating and cooling services, sales, and installation, available 24 hours. Our main office is in Center Line and we have branch locations in Troy, Warren, Hazel Park, Macomb, and Sterling Heights as well.
Selecting the perfect heating and/or cooling solution for your home or office begins with contacting us and speaking with our knowledgeable staff.  We can answer any questions you may have, and schedule a free home comfort consultation at your convenience.  Your HVAC sales specialist will walk you through our large selection of equipment options, and eventually find the right solution that fits your home comfort needs, and budget.
For duct cleaning, we happily refer our customers or anyone searching for duct cleaning to Safety King Air Duct Cleaning.  They have an outstanding reputation and can accommodate any duct cleaning or sanitizing needs. You can find them online at www.safetyking.com.
We specialize in the sales and installation of PCO UV air purification systems.  These units provide state-of-the-art UV technology that installs easily into your air ducts, eliminating bacteria, mold, dust, odors, and other airborne pollutants at the microscopic level. Visit our UV air filtration page for more information and pricing.
Our service call special is $99, which includes a 15-minute equipment inspection by our technician. If the technician identifies any problems, they will provide an on-site estimate for repairs/service. The $99 service call fee is not deducted from any repair or installation job thereafter.

Yes. Over the years we have professionally installed hundreds of hot water heaters for Michigan homeowners. Contact our office to get a free estimate.
Absolutely. Over the years, there have been significant advances in heating and cooling technology. As many homes or facilities can't support conventional HVAC duct systems, there are many options on the market for duct-less, or small-duct HVAC systems. For ductless, or wall-mounted HVAC systems, we offer expert service and installation for Trane Ductless Systems. For homes or facilities that need a more efficient duct system that can't support conventional (bulky) duct-work, we provide expert service and installation for Unico Small Duct Systems, where compact, flexible coils replace standard ducts, delivering heated or cooled air to every space. This solution requires little, or no remodeling. Contact our office for more information.
With a Zone Damper System installed by our certified technicians, you can have complete control over the temperature in any space in your home or office. Each room has its own smart thermostat where you can easily regulate and automate the climate in any space. Although these systems are typically installed in new builds, we can also install them in most homes or facilities.  Contact our office for more information.
Servicing or installing window AC units does not fall within our expertise, we do offer service and installation for wall-mounted HVAC units, however.
A.S. Contrera LLC is our commercial HVAC division. We have a large list of commercial clients that we serve across Southeast Michigan, and can fulfill any commercial HVAC contracting needs you may have.  We have a full-service sheet metal fabrication shop at our Center Line location where we can accommodate any sized HVAC customization project.  Some of our commercial HVAC specialties include Rooftop Units (RTU), Tube Heaters, Makeup Air, Kitchen Hoods, Kitchen Ventilation, and more. Visit our commercial HVAC website for more information.
At the very minimum, all of our heating and cooling systems meet the latest standards for energy-efficiency, while we also have equipment that will provide maximum efficiency-ratings (check out our Energy Savings Calculator).  Typically, the higher the rating, the more expensive the equipment.  We welcome you to contact us and we'll help you pick the best equipment based on your energy-consumption needs, and budget.

Testimonials

What Your Neighbors Are Saying...

"This company is great. We had a complete system installed. The installation team were very informative and respectful. When they left it looked like no one had been here, it was clean. The sales person Eric was great he really helped us understand every thing about the system. He also was instrumental in helping to fine tune our system. I have never been involved with a company that really cared about customer service as Mr. Furnace."
