AC Repair in Boston

• Thermostat Is Set Incorrectly: If your AC is constantly running , but your home isn’t getting any cooler, you may have simply set your unit to “fan-only” mode which can be adjusted in a second.
• Refrigerant Leak: If you use the air conditioner constantly, a joint can become loose which causes the refrigerant to leak. Sometimes it could be due to a service valve or the leak could be completely random. In order to prevent another refrigerant leak, make sure the unit is serviced before you turn it on for the summer months.
• Blown Out Breaker Switch: When a breaker has too much current, it will turn off for safety reasons. Air conditioners use a significant amount of current which can trigger the flip breaker to turn off.
• Broken Compressor: When the compressor isn’t functioning, the entire HVAC system won’t work. This issue is typically overlooked, unfortunately. If the compressor isn’t working, the refrigerant gases can’t be taken from the evaporator and converted into high-pressure gas. Compressors typically stop working because of electrical failures, refrigerant issues, and overheating.
• Dirty Coils and/or Fan Blades: When the air conditioner’s coils are dirty, there is a major lack of air flow which causes hot air to be blown out and which may cause your system to overheat. Dirty fan blades also have to work harder to do their job. Make sure to schedule your
  annual AC inspection to ensure this does not happen to your system!
• Dirty Air Filters: If you don’t change your air vent filter regularly, air can’t pass through your HVAC system efficiently. This means it’s going to take a long time to cool your home, and the longer the cooling cycle, the more chance there is that your AC will freeze and completely stop working.
• Lack of Maintenance: Most air conditioner breakdowns are caused by simple things that would have been fixed during a routine maintenance appointment. Make sure to have your AC serviced at least once or twice a year.
• System Needs Replacing: This is one of the most common reasons air conditioners stop functioning. Your air conditioner undergoes a serious amount of stress when it’s extremely hot out, and if it’s too old to handle that stress, it may break down beyond repair.

• Thermostat Set Too Low. Don’t turn the temperature down to an unrealistic setting. The house does not cool any faster this way, and this can cause unnecessary wear and tear on your AC unit.
• AC Is Too Small. Did your last HVAC company install an AC unit that is too small for your home? If so, it will run constantly in an attempt to reach the proper temperature, costing you more money on your energy bill without keeping you cool enough.
• Air Ducts Are Too Large. When ducts are too large, the unit can’t distribute cool air properly or handle the air flow.
• Air Filters Need to be Changed. Dirt, dust, pet hair, and other debris can clog air filters, hindering the ability of air to pass through the system and causing your AC to run longer to try to reach the desired temperature.
