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. "

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

If an air conditioner is younger than 10 years, it’s worth trying to repair it in most cases. Some basic maintenance or a cleaning might bring it back to working condition. However, many HVAC pros swear by the “5,000 rule.” If the estimated cost of your repair multiplied by the unit’s age is more than $5,000, it’s time to replace it.

Most HVAC surge protectors last about three to five years, depending on how often your home experiences blackouts or brownouts. If your unit is susceptible to more frequent electrical surges, consider replacing your surge protector every two years. Consult your HVAC professional to determine when and how often to replace your HVAC surge protectors.

Winterizing can still help you save money on energy costs and help prepare your AC for its work next year when you turn it back on. We suggest planning for at least some maintenance, even if winters are mild in your area.

Yes, the furnace and AC use the same blower. The blower is located in the base of the furnace and pushes hot air out of the furnace and into the ducts. It also pushes cool air through the home when the air conditioning is on. Even though the furnace and air conditioning work independently of one another, the blower is an essential component for both systems.

A blocked return air vent can cause your HVAC system to work much harder and, therefore, less efficiently. The result is higher utility bills and poorer air quality. A blocked return air vent can also cause unpleasant dust, dander, and odors to linger in your home’s air.
