"Had an issue where my air conditioning just wasn't working right anymore. Called Mike because he'd previously fixed any issue with my furnace and was pretty comprehensive. He came out in less than 24 hours. Showed up right on time. Walked me through every step he was taking along the way. Showed me how my AC unit had gotten completely clogged up with cottonwood. Proceeded to clean that up, added some additional freon and within a couple hours things were right as rain. You can just tell that he's an honest guy. Didn't try to upsell anything. Showed me the problem, told me the fix, and did it. Would recommend to anyone."

"Scheduled service to replace a leaking faucet.  They arrived on time, were polite, courteous, and professional.  $238 seems like an extremely high price for 15-20 minutes worth of labor.  The relatively simple repair job was done quickly, and if not for the seemingly high price, would rate them excellent overall.

"Went very well and I had a new furnace filter and asked if he would switch it for me which he did no job he said. Also they accepted the national fuel $50.00 rebate. So you just pay them fill out the form and get your $50. check in mail from national fuel. It was inexpensive and tmark still excepted their own coupon on top of the rebate. Want to call back for my central air unit in spring hopefully with a coupon."

"There is never a good time for a hot water heater to go, and in my case it was the Friday before a long 4th of July weekend. A lightning strike sent a surge that ended up causing some issues to my tankless hot water heater and this unit was less than a year old and installed by Cellino. Making a late night call, an answering service took the call and left a message. Shortly there after the owner Tony called to discuss the problem. A tech was sent out the next day and unfortunately the Supplier needed to be contacted to help diagnose the problem and make sure it was covered under warranty. The fact that it was a holiday weekend and the supplier was closed, Tony came out personally and installed a temporary water heater for my wife and my young boys. Upon the arriving of the part, Tony came out first thing and was prompt and professional always being careful to put on his shoe coverings as to not tract dirt in the house. He fixed the heater and was so professional in the process. I would highly recommend Cellino plumbing to anyone who had a plumbing or HVAC need. Its always amazing when the owner comes out to personally take on the job at hand. Its no wonder why the company always has great reviews, exceptional leadership from a hardworking knowledgeable founder."

Emerald Heating & Cooling was founded in 2000 by Marty and Carrie Sheehan, who combine their strengths to offer great HVAC service to the local area.\n\nThe business began after founder Marty Sheehan worked for an HVAC company and trained under a wise technician who told him “be like the duck on the water.” By this, he meant that ducks always appear graceful and in control above the water, while below the surface they are trying hard to stay afloat. It’s a metaphor for working hard while doing a beautiful job, hustling without mistakes, and doing great work without the fuss.\n\nMarty has taken this mindset and applied it to every aspect of our business, from the logo to the mission. This is how we approach every job we do.

Air Conditioning questions, answered by experts

Fixing a leak in an AC unit costs $200 to $1,600, depending on the type of leak and any related damage. But depending on the age and condition of your AC, it might make more sense to replace the AC unit instead of repairing it. If your AC is only a few years old and relatively problem-free, then repairing it is the right call. But if it’s nearing a decade old and has other issues, consider replacing it.

Yes, scorpions can enter a home through AC vents, especially if the system is not well-sealed. As excellent climbers, they can scale a home's exterior and squeeze through gaps as small as 1/16 of an inch. Scorpions are often attracted to the moisture around air conditioning ducts or seek cooler areas during hot weather, using vents as a pathway inside. They may slip through small openings where the duct meets the vent cover and travel within walls before emerging. To prevent this, inspect your vents, seal any gaps, and consider installing fine mesh screens.

It depends on the size of the space you’re cooling down. If you’re looking for the most affordable way to cool an entire house over a long period of time, then central air will be more cost-effective. But when it comes to cooling down a couple of rooms or one floor, a window unit may be the cheaper option, with both a lower cost to install and less energy used to run.

If your home has an existing forced-air heat system, you can add a central air conditioner to it. An HVAC technician can retrofit your forced-air heating system by installing an evaporator coil onto the furnace plenum, the box next to the furnace that draws in air. Once installed, the air conditioning coils use the furnace’s blower to circulate the air.

Air conditioners can stop working in the middle of the night for many reasons. Your local power grid might shut down late at night. Power surges can also trip your breakers if too much power is being used in the area at the time. If your AC is connected to a digital thermostat, it gets naturally cooler at night, so the outdoor temperature might dip below the automated setting to turn the cooling system off.
