"I would recommend Preston and Mallard Mechanical to anybody in the area looking to buy a new furnace/AC, or even just general HVAC maintenance. We closed on our house on a Friday with the AC not working and the furnace on its way out. We called Mallard Mechanical that morning and the equipment was ordered that same day and the install scheduled for the following Tuesday. The day of the install Preston was on site right on time and got our old AC and furnace torn out and the new system put in all in the same day. He was extremely professional and kept a VERY clean work site. He made sure to go over everything about the new system with my wife and I and even took care of setting up the city inspection for the new system. Last but absolutely not least, Mallard Mechanical's prices are extremely fair and I cannot imagine finding better service anywhere else for as good of a price as we got with Mallard Mechanical. Thank you again to Preston and Mallard Mechanical!"

Heating and Air Conditioning questions, answered by experts

Mold in your air conditioner isn't a good thing, as it can be harmful to your health. If the mold travels through the ductwork or is blown out of the A/C, you and your family can inhale mold spores and develop respiratory illnesses and other problems. Preventing mold from growing in the air conditioner will help protect your health.

The size window AC you need depends on the BTU and the size of the room you’re cooling. For a room with 8-foot ceilings, look for about 20 BTU per square foot of the room. For example, a 12-by-12-foot room should have an air conditioner with 2,880 BTU. You can buy something slightly more powerful, but don’t overshoot the BTU for a small room, or you’ll waste energy and have higher bills.

Many HVAC companies offer free quotes and free estimates for repairs and new HVAC systems. Others offer low-cost quotes or apply the cost of the estimates or diagnostics to your final bill if you hire them. Be aware that some companies advertise free HVAC quotes and recoup the costs by charging more for their services. Free HVAC quotes are never truly free—they cost the company time and effort—so be a good customer. Also understand that you may end up paying for free quotes in another way if you don’t hire a reputable company.

Most HVAC companies recommend against setting your AC below 70 as it could freeze up the system and cause more problems. Regardless of how hot it is outside, there is generally a 20 degree difference between the outside and inside temperatures, so even if it’s 100 degrees outside, your AC will likely not be able to cool your home to 70 degrees.

Dirty filters are almost always the cause of poor airflow, so they should be regularly cleaned and then replaced as needed. The fan blades can also get dirty, so they should be cleaned when the unit is turned off. Make sure that the outdoor area around the back of the unit is unobstructed. Trees, shrubs, trash, and other objects could be too close to your unit.
