Kevin did a really good job. Knowledgeable, friendly, and courteous. Kevin completed his assessment of our A/C issue and reviewed his findings with us. He clearly explained our problem and what will have to be done to fix it. He’s a good guy. Below there is a section about pricing.

Questions & Answers
What's the difference between central and ductless AC?
Central AC systems use ductwork to distribute cool air throughout a home. Ductless systems, also known as mini-splits, don’t use ducts and allow for independent temperature control in different areas. This can provide more flexibility and energy savings for individual spaces.
How can I reduce my AC costs?
To reduce costs, keep your thermostat at the highest comfortable setting, use ceiling fans to circulate air, and close blinds or curtains during hot days. Routine maintenance, such as cleaning coils and ensuring refrigerant levels, also helps maintain efficiency.
Why is my AC freezing up?
An AC can freeze due to restricted airflow, usually from a dirty filter, or low refrigerant levels. It can also happen if the evaporator coil is dirty or if the temperature is set too low. Regular maintenance can prevent these issues.
How can I improve my AC's efficiency?
To improve efficiency, regularly clean or replace filters, ensure your ductwork is sealed and clear of obstructions, and use a programmable thermostat. You should also keep your outdoor unit free of debris and ensure all vents are open and unobstructed inside your home.
