"I haven’t cleaned my split AC unit for over a year. Called Paradise Ac to come and check it out. Lance the owner was really professional and responsive. He cleaned out all the mold and dust in the unit that I couldn’t see. My Ac is blowing cleaner air and it makes a big difference. I highly recommend Paradise Ac for all your service needs."

"Our rental unit on the north shore of Kauaâ  i had just been deep cleaned 60 days prior to hiring Alben Rivera & his crew. We are restarting fresh with a new maid service. And what a contrast between what we had been receiving & Albenâ  s performance! This service was far & above all the others! He & his crew work very hard, seeking out what everyone else misses! My carpets & upholstery look new! Spaces under the refrigerator, oven, beds, sofa, chairs, curtains, tile floors look cleaner than I have ever known. His service is a very good value! Next time I need this service, Kauaâ  i Cleaning & Maintenance is getting the call!"

Heating and Air Conditioning FAQs, answered by experts

After a while, dust, dirt, and other debris accumulates on an AC unit's coils and filters, making it less efficient and spreading allergens and other air pollutants throughout your home. Cleaning your AC unit will keep it running efficiently, minimizing future breakdowns and improving your indoor air quality.

While you’ll pay more upfront for a brand-new HVAC unit, you can save money in the long run. Here’s how to save on your new HVAC system:

  • When purchasing a high-efficiency system, your energy bills will be lower in the future.

  • You may be eligible for special offers from your local energy company.

  • Depending on the system, you may be eligible for HVAC rebates and tax credits.

  • Choose to replace your air conditioning unit and furnace simultaneously to save on labor and installation costs. 

Set your house temperature between 55 and 85 degrees Fahrenheit while on vacation, depending on the season. If it’s winter, don’t go below 55 degrees. In the summer, the best AC temperature for energy savings is no higher than 85 degrees. You can save anywhere from 10% to 15% on your energy costs by adjusting the temperature while you’re away. If you have a smart thermostat, set up vacation modes for each season. On your way home, turn off vacation mode to allow the home to warm up or cool down before you arrive.

Replacing both an AC and a furnace takes a full day on average, ranging from eight to 12 hours. The process involves removing the old units, installing the new ones, and ensuring all connections are properly made. If both systems are being replaced simultaneously, it can take longer than installing a furnace alone, so plan accordingly.

You can adjust uneven airflow in your home by adjusting the dampers on the vents. However, if the temperature feels consistent throughout the home, don’t worry too much about uneven airflow. Generally speaking, larger rooms should receive more airflow than smaller rooms, especially if they only have one vent.
