"Rob was the service technician who came by for check up on our Trane AC Unit. He was professional and courteous. He took time to explain and label damper settings for future reference. He was the best HVAC technician I have ever encountered thus far. Rob is definitely an asset to McCrea company. If I ever need service again, I want Rob to be the one to service my AC Unit. Thank you!"

"Michael did an excellent job cleaning our dryer duct vent - the proof was in the before and after photos - amazing! He was pleasant, professional and explained each step in the process. He went above and beyond to ensure he removed all of the lint. The cleaning took less than an hour. I would highly recommend and will us this service again. Thanks so much, Michael!"

Heating and Air Conditioning FAQs, answered by experts

Yes, you can build a deck over your outdoor HVAC unit, but you need to leave at least 5 feet of vertical clearance above the unit. If you don’t want your deck to be that high off the ground, you could build a floating deck in another part of your yard—again, as long as you leave at least 4 feet of horizontal space between the deck and your AC unit.

No, you should not run an air conditioner with a Freon leak. If you think your AC unit is leaking refrigerant, shut it off immediately. When you keep using a leaky air conditioner, it could damage the unit and release more refrigerant. After turning off the AC, have an HVAC pro come take a look at the unit.

The higher the BTU rating an air conditioner has, the more effective it can be at cooling your space. It will cool off your room faster in the short term. However, over the long term, if the unit has too many BTUs for the space, it can wear down the unit faster and shorten its life span.

The cost to replace an AC evaporator coil is typically between $600 and $2,500, with an average cost around $1,300 to $1,350. The price of the coil itself can range from $550 to $1,100, depending on the brand, size, and style, with professional labor adding around $700. Replacing a condenser coil is generally less expensive, costing about $800. Because this repair involves handling refrigerants, it requires a licensed AC professional. Regular inspections, which cost between $200 and $600, can help prevent costly coil replacements.

There are a few ways to determine if a vent is open or closed. You can inspect the vent and examine the position of the fins. If there are spaces between them, the vent is open. If the fins are flat and touching, the vent is closed. You can also stand under the vent when the system is running to see if you feel air flowing through it.
