With 5+ years experience in the industry, Gary is your guy at Chapman's Heating and Cooling! Free estimates, family owned and operated, no corporate overhead, fair pricing, and perfection guaranteed, the first time around. What do you have to lose? Give us a call, let us get this job done together, the first time.

"First, this was an A/C repair, not install, but I can't say enough about this company! 1. I called, and the owner picked up the phone! 2. He listened to my concerns and was able to stop by and evaluate the issues with several hours. 3. He was prompt and accurate in his description of the issue, what parts on under warranty, how long for the parts, and the cost. 4. Knowing this was a rental property, he also advised of things seen and that may need to be addressed and once again confirmed that I really wanted to spend the money to fix the issue. 5. His time from evaluation to repair was less than expected, and once fully disassembled, he found he could perform the fix for less than expected - and he did not try to play games, he advised me of the change and the lower charge. I hire and work with a lot of contractors, repair people, etc. both for my business and my job. I can tell you I am shouting this company's work ethic high and wide. "

With decades of experience, we specialize in residential plumbing, heating, air conditioning, and electrical work. Our locally owned and operated team is committed to delivering reliable service, upfront pricing, and top-notch customer care. Whether it’s a routine repair or a full system installation, Cellino’s licensed technicians bring comfort and peace of mind to every home we serve.

"I’m reluctant to leave a negative review, but my recent experience with Cellino has left me no choice. I initially hired Cellino for a greenhouse HVAC project, based on a positive recommendation and previous great service with a furnace issue. On September 6, Chris came out to assess the job, spending significant time taking measurements and photos, and assured me they had handled similar projects. After weeks of visits and reassurances, we received a quote on September 18. Though it was higher than others, I trusted Cellino based on their professionalism. However, on October 22, over a month later and after multiple assessments, the installation team informed me that the heater they specified was actually overpowered for our greenhouse—news that should have been caught early on. This oversight led to weeks of back-and-forth exchanges, ending with us exchanging the heater for a more suitable model. This delay has cost my business thousands in lost stock due to inadequate heating."

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. The 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. Marty 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.

Heating and Air Conditioning questions, answered by experts

It’s critical to use the right size AC for your space and not go too small or too big. If you purchase an undersized unit, it won’t properly cool your house, and it has to work harder to reach the optimal temperature. This will eventually wear your unit out. An oversized unit can spell trouble because it will turn off and on more frequently, which also wears out your AC unit. An oversized unit also causes humidity in the home.

You can run an HRV with air conditioning—assuming that you decide to keep the system on during the summer. The HRV will continue to bring in fresh outdoor air, which will then flow into your AC unit and cool down your home. It will also keep moving the stuffy indoor air out of your house.

No, it's not safe to keep using your unit when it's frozen. Not only can running a frozen unit lead to damage, but it can also potentially overheat, making it a fire hazard. Therefore, it's always best to turn off the AC unit as soon as you notice any ice.

If your whole house is cold that’s one thing, but what if you only have a few rooms that are cold? First, you need to determine why this may be happening. A good place to start is to investigate the potential causes listed in this article—heat transfer, airflow, thermostat problems, humidity, and insulation. Once you’ve narrowed down the issue, you’d apply the same principles to the cold rooms as you would to the entire home.

If there’s a freon leak in your home’s AC unit, it will cause the system to work overtime to cool the house. That issue will result in higher energy bills and it will take much longer for cool air to disperse throughout the home. If your system has a freon leak during the summer, it can make hot days miserable. That’s why it’s important to hire an HVAC professional to resolve a freon leak as quickly as possible.
