  • Do you work on all brands of air conditioners?

    Yes, Dohner Heating & Cooling services most major air conditioning brands and models. Our technicians have the experience to diagnose and repair a wide range of systems.

  • How do I know if my air conditioner needs repair or replacement?

    If your system isn’t cooling properly, requires frequent repairs, or is over 10–15 years old, it may be time to consider replacement. Smaller issues can often be repaired, but an older system that struggles to keep up may be costing more to run than it’s worth. A professional inspection can help determine the best option.

  • How often should I service my air conditioner, and does it really matter?

    Your AC system should be serviced once a year, ideally before summer. Regular maintenance improves efficiency, lowers energy bills, and helps prevent unexpected breakdowns during the hottest months.

  • Why are my cooling bills higher than usual?

    Higher energy bills are often a sign your system is working harder than it should. This can be caused by dirty filters, lack of maintenance, aging equipment, or airflow issues. Addressing these problems can improve efficiency and reduce costs.

  • Why is my air conditioner not cooling properly?

    This is one of the most common issues homeowners face. Causes can include a dirty air filter, low refrigerant, thermostat problems, or restricted airflow. If your system is blowing warm air or not keeping up, it’s best to have it checked before the problem gets worse.
