"We called Jay when our A/C stopped working last spring. He was quick to take a look at our existing unit and give us options for repair or replacement. We chose to replace due to the age of the Air Conditioner. We were able to choose from a variety of brands, and had one installed within a week. We felt he was fairly priced and very knowledgeable, and best of all - we stayed cool all Summer!"

"In the midst of the hot weather, our A/C decided to stop working. My friend referred Priority. They were able to make it out to me very quickly and repair our A/C at an affordable price. The guys were very knowledgeable and helpful in explaining how things work and what was wrong. I would definitely recommend Priority for any heating and cooling needs."

"We were very impressed with A & C Heating and Cooling. Their online scheduling tool was convenient, user friendly, and there was a variety of time slots available. The appointment follow up, reminders and arrival tracking map were timely and helpful. Our technician, McKinley, was amazing!!! He was very courteous, knowledgeable and efficient. He diagnosed the problem quickly, installed the needed part, and ran tests to ensure the unit was running at peak performance. He educated us about our unit by explaining how it operates, what caused the problem, and how the replacement part would remedy the problem. We are VERY satisfied with their service. We give this company and our technician our highest rating, and we would highly recommend them to anyone in need of quality heating and cooling installation or service. ."

"After setting my appointment with Kevin, his crew of Lewis and Fred arrived on time and we’re very professional. They took some before and after internal photos of the ducts to a home we just purchased. My wife has allergies and pet dander is pretty high on her list...the amount of pet hair found in the before photos was incredible, after the cleaning was done, not a trace of hair. They also recommended a good filter to use and next time to service ducts. Highly recommend Michigan Home Comfort...thanks guys!"

FAQs for heating and air conditioning service projects in Saint Clair, MI

Knowing how long your existing HVAC units can last is essential to determine if you need a repair or replacement. Typically, most modern air conditioning units can last between 15 to 20 years, and most furnaces can work properly for 15 to 30 years. If your HVAC system is on the older side and you decide to replace one unit, it might make sense to replace both simultaneously to save on costs and future hassle.

While different HVAC contractors might offer higher or lower prices than competitors, the best time to replace your HVAC system is when customer demand is low. The beginning of summer and the beginning of winter bring the most demand for HVAC systems, so if you can, consider replacing your HVAC units in the early spring or fall. Many HVAC companies offer special off-season coupons that help lower the overall cost.  

The average cost to hire an HVAC contractor is between $50 and $150 per hour if charging hourly. However, some HVAC contractors will charge a flat fee by the type of service they are performing—for example, an inspection can cost between $150 to $500. Keep in mind that emergency repairs—which are made after business hours or around major holidays—generally cost more than scheduled repairs.

Yes, most states require HVAC technicians to be certified, and for good reason. Hiring an unlicensed HVAC technician could lead to poor quality work, costly future expenses, and potential code violations. 

As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include: 

  • The owner, principal, or relevant manager passed a criminal background check

  • Required to have applicable state and local licenses

  • Maintain an average star rating of 3.0 or better on our network, if they have at least one review

  • Paying to advertise their services

  • Meeting any other eligibility criteria required by Angi

Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.

The average cost of HVAC repairs is around $350. However, that price can be as low as $100 or as high as $2,000 or more, depending on the repair. For example, replacing a capacitor is a relatively inexpensive repair, ranging from $100 to $500. However, a compressor repair is a more expensive repair, ranging from $750 to $2,000.
