"We noticed a foul smell coming from one of the vents in our HVAC system. We turned the system off and called AC Dave. Dave sent Justin and James to troubleshoot the problem. They quickly found a tear in one of our ducts--and the remains of a dead rodent. They cut open the duct, cleaned it and resealed it. We had heat again, about an hour after they arrived. Very fast and competent service."

"From beginning to end, The Right Choice Heating and Air Conditioning Co. provided superior quality customer service and onsite work. From scheduling, to multiple follow-ups and reminders, re-confirming exact appointment time, and the post-inspection follow-up, they have truly impressed us. More importantly, Michael Taib, the technician who performed the work at our home, was indeed a true gentleman and professional. He was extremely knowledgeable and patient. I am familiar with the type of HVAC related work requirements, the lingo, and technician data. I quizzed him several times and he constantly responded with 100% honest and factual answers. He tirelessly worked on both of our HVAC units and performed the necessary services and repair. He was polite, courteous and clean. His most impressive talent was ensuring my wife's absolute confidence in his work after she grilled him with so many questions! We will continue to refer True Choice to all our friend and family! Call them; you will not be disappointed."

"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

Yes. Return air vents are responsible for gathering and pulling in the warmer air. Once they draw it in, your system conditions the air by removing the warmer molecules from it, allowing your air conditioner to dispense the cooler air back into your home. Not only does this create a more comfortable environment for you, but it also keeps your air conditioner from overworking, resulting in lower energy bills. 

Replacing an HVAC system does not always include new ductwork. The decision depends on the condition of your existing ducts. If they are in good shape, correctly sized for the new unit, and meet current standards, they can often be reused. However, if the ducts are damaged, poorly designed, or improperly sized, they will likely need to be replaced or upgraded to ensure the new system operates efficiently. An HVAC contractor will assess your ductwork and recommend the best course of action. Typically, ductwork is purchased separately, and a full replacement will add to the overall project cost.

Most HVAC service calls include diagnostic fees, which could include checking on a specific issue you’re experiencing or running through a routine inspection checklist. If you called for a particular problem, the service call will also include an estimate to fix the issue, including materials and labor. Depending on your HVAC technician and the service you requested, you might also get a general inspection of your system components to ensure everything is working as intended.

As mentioned above, not all HVAC Schrader valves are necessarily the same. While the valve core and pin or spring size on Schrader valves used for HVAC are generally similar, the valves are not all universal and interchangeable. The size of Schrader valves varies depending on whether it's used in an air conditioner, bicycle tire, or motor vehicle tire.

Yes, but they don’t feel the same as an AC-cooled room. You’ll feel cool, moist air, opposite from an HVAC system that dries the air as it cools. Ventless units also have less tonnage than alternatives like ductless and central air, which means they aren’t as capable of quickly cooling large spaces or circulating cold air.
