Why is my air conditioner running but not cooling?
Several issues can cause an air conditioner to run without properly cooling, including restricted airflow, a dirty air filter or coil, electrical problems, low refrigerant, or a failed component. CheckMark Mechanical can diagnose the system and identify the cause before recommending repairs.
How often Should my air conditioner be serviced?
Most residential air conditioning systems should be professionally maintained once a year, preferably before the cooling season. Regular maintenance can help improve the efficiency, identify potential problems, and keep your system operating reliably.
Why is my air conditioner freezing up?
An air conditioner can freeze because of restricted airflow, a dirty air filter or evaporator coil, blower problems, or a refrigerant issue, If ice forms on the system, turn the cooling off and allow it to thaw before having the cause diagnosed.
Should I repair my air conditioner?
The best option depends on the age and condition of your system, its repair history, efficiency, and the cost of the repair needed. CheckMark Mechanical can evaluate your equipment and explain your repair and replacement options so you can make an informed decision.
How long does an air conditioner typically last?
Many central air conditioning systems can last 12-15 years or longer with proper maintenance. System lifespan depends on installation quiality, maintenance, operating conditions, and how heavily the equipment is used.
What size air conditioner does my home need?
The correct air conditioner size depends on more than your home's square footage. Insulation, windows, air leakage, sun exposure, and other factors affect the cooling load. Proper sizing helps provide better comfort, efficiency, and equipment performance.
