A working air conditioner is essential for comfort during Michigan’s hot and humid summers. Comfort Plus Heating & Cooling offers professional ac repair services to both residential and commercial customers in Troy and the surrounding areas of Oakland County. With 24/7 emergency response, upfront pricing, and a team of licensed technicians, we deliver fast, dependable solutions that restore your comfort when it matters most.


Skipping routine heater service maintenance can have expensive consequences. Over time, dust buildup, worn parts, and neglected filters strain the system. This leads to reduced efficiency, higher monthly bills, and even complete breakdowns in the middle of winter. Worse yet, neglected systems can create safety hazards like gas leaks or carbon monoxide risks.
By contrast, scheduling regular heat maintenance services keeps your system clean, efficient, and safe. It also ensures your manufacturer’s warranty remains valid, protecting you from unnecessary replacement costs. A small investment in preventative service today can save you thousands tomorrow.


Blocked ducts, poor calibration, or system wear can cause hot and cold spots in different rooms. Routine maintenance ensures even heating and keeps every area of your space comfortable.

Grinding, banging, or rattling sounds often mean loose parts or mechanical wear. Tune-ups tighten components and lubricate moving parts to prevent costly repairs.

When utility bills increase despite regular use, your heating system may be straining due to worn components, dirty filters, or airflow problems. Professional heater service and repair restores efficiency, lowers costs, and reduces system stress.



By scheduling a heater maintenance service each year, you protect your investment, improve your home’s comfort, and extend the lifespan of your equipment.

Posted onDavid ByrneTrustindex verifies that the original source of the review is Google. Nick W. and his crew did a fantastic job installing our gas line. Labor was completed in record time!Posted onScout LabradorTrustindex verifies that the original source of the review is Google. Chris’s and his crew came out 05/23/25 to remove and install an Air Conditioner and Furnace. I initially called about servicing my broken air conditioner. He called back and was able to come out quickly. Due to the very old age of my unit, I decided I didn’t want to fix but rather replace. Since my furnace was even older I wanted them both done. He had the items in stock and was able to come out on a day that worked good for both of us. They arrived on time and did a fantastic job. Very neat and conscientious of how and where piping and materials were placed and hung. His crew was friendly, helpful and so professional. So far so good, furnace is working great. Will get to try out the air conditioner soon😊 I highly recommend Comfort Plus.Posted onMacomb RentalTrustindex verifies that the original source of the review is Google. I inquired about registers and if they had any in stock. The guy working there was very helpful and shared the type of material I needed, supplier info, and also other stores that could have my product. Even though I didnt go to the store, the guy went out of his way to help out. Great customer service!Posted onMarvin KhemmoroTrustindex verifies that the original source of the review is Google. Quick response, honest, and reasonable pricingPosted onGlynnTrustindex verifies that the original source of the review is Google. I am a new customer and I can’t say enough good about this company. Two very polite men came all the way to Canton, MI to replace the air conditioning and furnace. They also installed a programmable thermostat and showed me how to install. It on my phone and how to use it!!! These guys were great. Just like service we had back when…..Posted onDerek BossTrustindex verifies that the original source of the review is Google. Great locally owned business! Knowledgeable and trustworthy. Always on time and on schedule for appointments, and very fair pricing compared to the big corporate hvac companies. Chris and his Comfort Plus team have been my go-to call for any heating and cooling needs for 8+ years now!Posted onSusan KestelootTrustindex verifies that the original source of the review is Google. Excellent service, always! Have had to utilize this company on a number of occasions. They never disappoint. Same day service, trusting staff, and always a job well done. Thank you!Posted onPaul HodginsTrustindex verifies that the original source of the review is Google. From start to finish, my experience with Comfort Plus has been nothing short of exceptional. Their team is a terrific example of professionalism and expertise, making them a standout choice in the HVAC industry. The customer service is unparalleled. I scheduled an appointment at 10:30 PM, and the technicians arrived at 8:00 the next morning—an impressive turnaround time. They arrived on time, fully prepared, and with a positive attitude. Their knowledge and skills were evident as they quickly diagnosed the issue with my HVAC system. The quality of their work is second to none. I needed to replace my 25-year-old A/C unit (which was leaking refrigerant) and furnace (which had a cracked heater core). The issues were thoroughly explained and demonstrated. Chris walked me through my options, and once I decided, the updated A/C and furnace were installed efficiently. The technicians made sure everything was running smoothly before they left and took the time to give me valuable tips on maintaining my system to ensure it runs optimally for years to come. Chris followed up with me after the service to ensure everything was still functioning well and to address any further questions I might have had. Comfort Plus excels in every aspect of HVAC service. Their combination of expertise, outstanding customer service, and dedication to quality makes them the top choice for anyone in need of HVAC repair or maintenance. The price was more than competitive, and I am happy to support a locally owned business rather than companies that are owned by large investment firms. I couldn’t be happier with their service and will undoubtedly turn to them for any future needs. Highly recommended!
