"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

It all depends on the unit’s SEER (seasonal energy efficiency ratio). A higher SEER rating means better efficiency and lower costs for your energy bills. 

Take a look at the product you’re considering purchasing and compare it to other models to decide which one is affordable upfront but will keep your energy costs low over time.

If left untreated, a frozen AC unit can lead to costly damage, especially to the compressor and evaporator coils. When ice forms on the evaporator coils, they become brittle and more susceptible to breaking. Plus, a freeze makes your AC system much less efficient, which means it's wasting energy and costing you more in your monthly energy bills.

Indications of an HVAC problem include inconsistent heating or cooling throughout your home, unpredictable temperature changes, or inadequate air flow from vents. Abnormal sounds such as grinding, banging, or hissing, and unpleasant smells like mustiness or burning are also potential warning signs. A rise in energy costs without an increase in usage may also imply decreased efficiency. An HVAC system that frequently cycles on and off or cannot maintain a stable temperature is malfunctioning.

A calculation method that your HVAC contractor will use to ensure your system does what it's supposed to is measuring duct output, or its CFM. The calculation requires knowing the cross-sectional area of the ductwork and determining the air speed past any given point within it.

If refrigerant levels are low, it can cause the evaporator coil to freeze up. Low freon causes a drop in pressure, which will make the coil too cold and cause moisture to freeze on the coil. Your system may be low on refrigerant because of a leak. 

Make sure to have maintenance performed twice a year, and contact your local HVAC technician if you suspect your system has low freon levels.
