"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!"

"We met serviceman Alex L. from DJ's today. He worked as long as it was necessary to diagnose and fix issues with our furnace humidifier. It needed several adjustments. He worked very diligently and the price was reasonable (especially by today's standards for pricing). We would definitely hire DJs again for other HVAC and plumbing work. We also appreciated the company's thoroughness in providing reminder calls and other contact on the day of service to ensure we met Alex at our home at the right time. This shows an emphasis on customer service that we appreciate. Both Charlotte and Karen were very helpful to us on the phone today as well."

"Brian spent the extra time to make sure I understood when filters need to be changed, when the water heater needs to be flushed, and general maintenance on the a/c unit. He is very personable and easy to talk to."

Heating and Air Conditioning questions, answered by experts

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.

If the air coming from your AC unit is cool but never quite cold, there are a few reasons this might be happening. For starters, it could signal that your refrigerant levels are low. If there are no other indications of this particular issue, like hissing noises or frozen refrigerant lines, anything from dirty filters to damaged condenser or evaporator coils could be responsible for the problem.

This depends on the extent of the freezing. Some ACs only need an hour or two to thaw out, but others may need a full day to completely unfreeze. Once you turn off the system to let it unfreeze, check it periodically to make sure the drain pan doesn’t overflow. When you turn the system back on, keep an eye on it to ensure it doesn’t start freezing again.

To lower humidity quickly, run a dehumidifier or your home's air conditioner or turn on exhaust fans to extract moisture. These methods can quickly and effectively bring your home's humidity levels to a comfortable condition. However, you should consistently practice humidity-reducing tasks to maintain proper indoor humidity levels.

While you’ll pay more upfront for a brand-new HVAC unit, you can save money in the long run. Here’s how to save on your new HVAC system:

  • When purchasing a high-efficiency system, your energy bills will be lower in the future.

  • You may be eligible for special offers from your local energy company.

  • Depending on the system, you may be eligible for HVAC rebates and tax credits.

  • Choose to replace your air conditioning unit and furnace simultaneously to save on labor and installation costs.
