"Jerry and James showed up on time. They cleaned a total of 17 vents and returns, and a dryer vent. The job took 3 hours. They patched up the HVAC vent where they cut holes to connect their vacuum to, cleaned up after themselves, and even locked the back door for me. I had to do minor clean up, but that was no unexpected. The weird smell in my son's bedroom is gone now. Overall, I am satisfied with the service, although the pricing was not the cheapest compared to other companies.

"We are very pleased with the job Dave did for us today. He was prompt and very courteous and did a professional job cleaning our carpets. Thank you for keeping the planned schedule as promised. We will recommend your company to our family and friends.

Stan"

"Mr. Bonhom (Mike) showed up on time and jumped right on the job. He explained that I didn’t have the issue I thought I had and did a thorough check on both my heating and A/C systems and told me when I should change my filters. His service call fee was great! I highly recommend 3M Mechanical!!"

Heating and Air Conditioning questions, answered by experts

HVAC companies may charge an hourly rate or a flat fee. Hourly rates typically range from $100 to $250 per hour, with an average around $175. Some contractors charge a flat fee for specific services, such as an inspection, which can cost between $150 and $500. The total cost of an HVAC service is influenced by several factors, including: the urgency of the service (emergency repairs after hours or on holidays cost more), the time of year, the type, size, and brand of your HVAC system, the specific repair needed, and whether you have a service contract.

Most AC repair technicians will take between two and six hours to carry out repairs, depending on the work needed and the accessibility of the unit. For example, recharging refrigerant lines should take one to two hours to service, while replacing a compressor, blower fan, or other major components can take five to eight hours. You can ask your AC repair technician how long they expect the job to take, but just in case, you should plan on being home and available for most of the day.

To keep your air conditioner in good working condition, you should have it serviced by a professional at least once per year, ideally in the spring before the cooling season begins. If your AC unit is 10 years or older, consider servicing it twice a year (once in the spring and once in the fall) to catch potential problems early and help it reach its full lifespan. During a service visit, a technician will inspect, clean, and replace parts as needed. Regular maintenance helps avoid costly repairs. As a DIY task, you can also clean the evaporator coils annually.

On average, replacing an AC compressor costs between $800 and $2,300, but it could cost as much as $2,800. There are a few factors that impact the price of a compressor replacement, including the type and size of the compressor, as well as the type of HVAC system and local labor rates.

No, for two very important reasons. First, it’s illegal to release refrigerant into the air or ground since it can be toxic and cause environmental damage. Technicians typically pump old or extra refrigerant into separate tanks for special disposal. Second, without professional equipment to read refrigerant pressure and levels, plus the AC’s suggested requirements, it’s impossible to know if you’ve removed the right amount of refrigerant. Stay away from a DIY solution here and seek an expert with the right tools.
