"My experience with Clean Air Genie was great. They were professional and knowledgeable explaining everything to me clearly and provided pictures and videos before and after the work was done. My air ducts were pretty bad (hadn’t been cleaned in 10 years) and they were able to get them very clean and sanitized. I appreciate that their prices were transparent and fair for the work. I will definitely recommend!"

"had such a great experience with HighPoint HVAC! The entire process was seamless and incredibly easy from start to finish. I was able to schedule an appointment right away, and the team arrived exactly on time. They were professional, friendly, and took the time to explain everything clearly. After finishing the job, they left the space spotless; you’d never know any work had been done. Their quality of service and attention to detail really stood out, and the pricing was very fair. I’d highly recommend this company to anyone looking for reliable, high-quality HVAC service"

"My dad is elderly and needed a new HVAC system. So I decided to find a person who could install a new HVAC system and we found Cody. Cody was very friendly, honest, and communicated very well. At one point he told us we could probably go another 3-5 years with the current system, but since my dad only has so many years left we told he to go ahead and install a whole new system in. He treated us like gold and even spent the time showing my Dad all the new features with the thermostat. I would highly recommend Cody for any repairs or HVAC needs you have."

Heating and Air Conditioning questions, answered by experts

Whether an HVAC damper should be open or closed depends on the season, the zone it controls, and the temperature in that zone. In the summer, open upstairs dampers and close lower-level dampers to get the most efficient cooling possible. In the winter, do the opposite. Cool air will naturally flow down to lower levels, while warm air will rise. This keeps your system from working harder and helps prevent common AC problems.

Yes, ventless portable air conditioners exist, and not all standard portable air conditioners must be vented through a window.

Ventless portable units, often called evaporative coolers, do not have exhaust hoses. They use a water reservoir and a cooling pad to add moisture to the air, making it feel cooler. These units work best in dry climates because humid areas cannot absorb much additional moisture.

For standard portable air conditioners that do require venting, a window is not the only option; they can also be vented through a door, wall, or ceiling. However, it is essential to vent these units properly. Running a standard portable AC without venting it is counterproductive because it needs to expel heat to cool the room. Failing to do so will only increase the room's temperature.

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours. 

The length of an AC cycle depends on the settings in your thermostat and the unit you have. Central AC doesn't constantly run at full blast the way that a window unit does. A cooling cycle in most homes is 15 to 20 minutes. Then, the unit stays off for seven to 10 minutes to circulate the cold air in the house before the cycle repeats. It should repeat two or three times per hour. A short cycle lasts less than 10 minutes and then turns off.

The cost to install a ductless mini-split AC system ranges from $2,000 to $14,000, depending on the type of unit, the number of zones or rooms, and the complexity of the installation. On the low end, a system for one or two zones in a single room costs around $2,000. Covering two zones for more rooms can cost between $6,000 and $8,000. For a larger multi-zone system to cover an entire home, costs can be $14,000. If you don’t already have an AC system in place, you may need to add the cost of permits, an electrician, and a concrete pad.
