You should change the air filters in your air conditioning unit every one to three months, depending on usage and the type of filter you have. Dirty filters can reduce the efficiency of your system and lead to higher energy bills.
It is not recommended that you install an air conditioning unit yourself unless you have experience and knowledge in HVAC systems. Poor installation can lead to inefficient operation and even safety hazards.
To improve the energy efficiency of your air conditioning system, you can seal air leaks around windows and doors, insulate your home, use a programmable thermostat, and regularly clean and maintain your unit.
No, air conditioning units require electricity to operate, so they cannot be used during a power outage unless you have a backup generator.
You should have your air conditioning system serviced by a professional HVAC technician at least once a year, ideally before the start of the cooling season. Regular maintenance can improve efficiency and extend the lifespan of your system.
The size of your air conditioning unit depends on several factors, including the size of your home, the number of rooms, and the amount of insulation. An HVAC technician can perform a load calculation to determine the appropriate size for your specific needs.
Air conditioning units can last anywhere from 10 to 20 years, depending on usage, maintenance, and the quality of the unit.
If your air conditioning system is over 10 years old, requires frequent repairs, is inefficient, or no longer adequately cools your home, it may be time to consider replacement.
