"AC Dave is a skilled and trustworthy HVAC company that does quality work at a competitive price. I had an aging four ton system that was on its last leg. My funds were tight at the time, so they suggested installing more efficient ducting to extend the system’s life. That was three years ago, which allowed me to save for the inevitable expense of replacement. And when that time came, I was given a comprehensive estimate and the installation went smoothly. They also did a follow up to tweak the system for maximum reliability. AC Dave is a small company, so you may not get next-day service, but they will work with you and stand by their work. In today’s less and less neighborly world, that is a real asset."

"AC was repaired timely and professionally by Tommy and his helper and then Juan and Edgar followed up two days later by installing blown in cellulose insulation in my attic to help ensure the efficient operation of my HVAC system. It's been hellaciously hot this past couple of weeks, yet these guys all did a bang up job, despite the heat. Fair price, professional, personable and efficient service. I would definitely recommend The Right Choice Heating and Air team to friends and neighbors!"

"A nice guy turned up on time to check my aging HVAC system to see there are any problems needing attention. He checked everything and gave me a clean bill of health. Other HVAC contractors have always presented me with a list of vague problems with a recommendation that I renew the whole system at $20,000 plus. It was refreshing to find someone honest for a change."

"I had estimates from four HVAC companies. Hilo Aire speaks VOLUMES without any regrets. Everything from A to Z went beyond my expectations. The crews were so good that they took their time to inspect and install the cooling and heating systems. I’m truly IMPRESSED. Ask for Chad and/or Brett. KUDOS to them and the crews."

Heating and Air Conditioning questions, answered by experts

Running a window air conditioner unit costs about $0.06 to $0.88 per hour. Choosing the correct size air conditioner can help it run more efficiently.

When deciding whether to repair or replace your air conditioner, several factors should be considered. It is generally worth repairing the unit if it's less than 10 years old, the warranty is still active, and you're dealing with a one-off issue. Most central AC units last about 15 years, while window units last 8 to 10 years. If your unit is approaching or has surpassed the 10-year mark and requires frequent or costly repairs (e.g., over $5,000), replacement is often the more sensible long-term investment. For older, inefficient, or out-of-warranty units experiencing multiple problems, replacing it is typically the better choice.

The best way to reduce heat upstairs is to release it by opening a window. Hot air rises, and if you can create some airflow by opening a window upstairs and also one on a lower level, the hot air should be pushed out of the home. Remember that fans pointing out the window do a much better job of circulating air than fans pointing into the home.

The average life span of an HVAC system is 15 to 20 years. Even if your old air conditioner is still functional, it isn't as energy-efficient as a newer system (especially one with an Energy Star designation). Older HVAC systems aren't as efficient, and the 10-year mark is when you should start making full system replacement plans. Twenty years in, that plan should be well underway rather than waiting for the unit to die.

Most HVAC companies charge a flat service call fee of between $75 and $150, which includes traveling to your home and inspecting your system to find the underlying problem. Keep in mind that these prices only include diagnostics and the actual repairs will usually be billed separately. If you’re calling for routine service, the service call will be included in your inspection and tune-up, with the total sitting around $150. Your prices could be a little higher if you have a very large home with multiple condensers and air handlers, as inspections and servicing take longer.
