"Came home at 5:30 after working all day to find my central air unit not working & my house at 87 degrees. With 2 small children - one having asthma, I panicked. Kenny came right out and within an hour had my unit back in business. Even checked my furnace and tested my unit to make sure everything was running the way it should. Super friendly & reasonable! 10/10 would recommend!"

"Just too expensive for what you get. Feels like a big company nickel and dime move. I get having a trip charge. Which was $109. But then to have the tech who was great btw (not his fault), but was tentative about fixing the problem because of creating more damage. Another $160 for a simple diagnostic charge, again without fixing the problem. I already knew the diagnosis. So he basically did a Band-Aid fix (greased the Knob) and still charged me over $280+ for what equated to be 10 minutes of work. It was ridiculously high for the service provided. Next time I?m going to an independent, local guy."

"We were extremely pleased with the service of FinMar Comfort. Sean was knowledgeable and professional. He installed a split heat/air conditioning unit in our sunroom so we could use it all seasons. He went out of his way to find us a unit that was reliable but fit our budget. Sean also helped us every step of the way with permits and warrenty information. Would defintely recommend FinMar Comfort"

Heating and Air Conditioning FAQs, answered by experts

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.

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.

If your AC condenser is nearing the end of its life, it might leak fluid or make loud or unusual sounds (like grinding or hissing). You might also notice that it isn’t heating your home as evenly or effectively as it once did. Also, an aging condenser will have to work harder to cool your home, which may force it to use more power and drive up your utility bills.

Most HVAC companies charge a flat service call fee of between $75 and $150, which includes traveling to your home and inspecting your system to find the underlying problem. Keep in mind that these prices only include diagnostics and the actual repairs will usually be billed separately. If you’re calling for routine service, the service call will be included in your inspection and tune-up, with the total sitting around $150. Your prices could be a little higher if you have a very large home with multiple condensers and air handlers, as inspections and servicing take longer.

Yes, it’s important to turn off your AC sometimes to give it a break and prevent it from freezing up. If your AC runs all the time, your system’s parts will wear down quicker, which may mean that you need to replace it sooner. Plus, using your AC constantly uses more electricity and leads to higher energy bills.
