"Riley was the technician who serviced my air conditioner yesterday. Riley always kept me informed on the progress of the work he was doing and before leaving THOROUGHLY explained the condition of my air conditioner and what I can do to extend its life. Fortunately my air conditioner, even though it’s 11 years old, is in great condition and I plan on doing things to prolong its life. Overall I would give Riley a rating of 10. He is an exceptional technician, knows his job, explains things well, and personable. The cost today was $17 for a replacement filter."

"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!"

"My wife and I decided to have a split entry heat pump installed, so I contacted 4 contactors. JoMac was first to respond, first to come out, first to submit a bid, and after I accepted the bid, Joe completed the work in short order. Joe listens to the consumer well and is anxious to do a good job on the project; he knows that happy customers mean more business. Joe is polite and outgoing; he even brought cuccumbers for us. Two days after the job was done, Joe called just to see how things were going."

Air Conditioning FAQs, answered by experts

The top reason to purchase an HVAC maintenance contract is the fact that it ensures you are detecting problems before they turn into expensive fixes. Secondly, this type of contract provides priority service, which is nice if it’s peak busy season. Finally, an HVAC maintenance contract provides discounts on parts and labor for repairs, which can save you a good amount of money if your unit breaks.

Deciding whether to replace just the AC coil or the entire system depends on the age of your unit and the overall cost. Replacing a coil is less expensive than a full system replacement, but it can still be a pricey repair. If your HVAC system is relatively new and still under warranty, or if the replacement cost is significantly lower than a new system, replacing the coil can be a worthwhile investment that restores efficiency and extends the unit's life. However, for older systems (nearing the end of their 10-15 year lifespan) or those with extensive damage, it is often more cost-effective to replace the entire AC unit. Mismatched coils in an older system can lead to inefficiency and future breakdowns, so a full replacement ensures optimal performance and avoids further costly repairs.

While Freon is mostly odorless, a Freon leak will produce a faint chloroform-like smell. Some people find that Freon's odor has a subtle sweetness to it. Some telltale signs of a Freon leak beyond odor include ice crystals on your evaporator coil, bubbling sounds, and hissing noises.  

The cost to repair an air conditioner averages around $350 to $450, but the price can range from $100 to over $3,000. The final cost depends on the type of air conditioner, the extent of the damage, and the specific parts that need replacement. For example, repairing a window AC unit typically costs between $100 and $250, while central air conditioner repairs can range from $300 to $3,000. A simple fix like replacing a dirty filter might only cost $10 to $50, but a major issue like a broken compressor could cost around $2,000 or more, potentially making it more cost-effective to replace the entire system. Due to the need for specialty tools and handling of refrigerants, repairs more complex than changing a filter are best left to a professional.

You should clean your air conditioner at least once per year, but you may need to clean your whole HVAC system (including the air ducts) more often. According to the National Air Duct Cleaners Association, you may need to clean them more frequently depending on factors like whether you smoke, have pets, or have allergies.
