"Tyrone replaced the whole HVAC system and he is a courteous and professional, licensedHVAC tech. I would not hesitate to hire him again for my HVAC needs.."
"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. "
"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
Dirty filters are almost always the cause of poor airflow, so they should be regularly cleaned and then replaced as needed. The fan blades can also get dirty, so they should be cleaned when the unit is turned off. Make sure that the outdoor area around the back of the unit is unobstructed. Trees, shrubs, trash, and other objects could be too close to your unit.
Whether an HVAC damper should be open or closed depends on the season, the zone it controls, and the temperature in that zone. In the summer, open upstairs dampers and close lower-level dampers to get the most efficient cooling possible. In the winter, do the opposite. Cool air will naturally flow down to lower levels, while warm air will rise. This keeps your system from working harder and helps prevent common AC problems.
There are many recognizable symptoms of AC compressor failure. They include loud banging noises, hot air being continually circulated in your home despite running the AC at full blast, uneven airflow and cooling, and electrical issues like constant surges due to the compressor working overtime. While some of these symptoms, like uneven cooling, can have other root causes, they are common indicators of compressor problems.
If your central AC is not blowing cold air, you should try resetting the system. Many systems have a reset button. Make sure your thermostat is off, then turn off the circuit breaker that powers your AC. Hold the reset button for three to five seconds, then turn the circuit back on. Set your thermostat to cool and choose a temperature cooler than the room. Your system should turn on quickly.
Don’t run your AC with a wet filter. It can cause your AC to work too hard, which will run up your utility bill and cause extra wear and tear on the system. You could also spread moisture and mold throughout your house. Turn off the AC, remove the wet filter, and check for cracks or clogs. Fix the problem (with a pro’s help, if you need it), and put a dry filter in place before you turn the system back on.
