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. "

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

Dirty filters are almost always the cause of poor airflow, so they should be regularly cleaned and then replaced as needed. The fan blades can also get dirty, so they should be cleaned when the unit is turned off. Make sure that the outdoor area around the back of the unit is unobstructed. Trees, shrubs, trash, and other objects could be too close to your unit.

If your HVAC system's capacity doesn't match the required CFM (Cubic Feet per Minute), imbalances can occur. An undersized system struggles to maintain desired temperatures, leading to discomfort. An oversized system might short-cycle, wasting energy and causing temperature fluctuations. Properly matching capacity to CFM ensures efficient and consistent heating, cooling, and home ventilation system performance.

Yes, a dirty evaporator coil can freeze up. Dirty evaporator coils can’t absorb or transfer heat properly. The dirt and grime restrict airflow, which is needed to move heat throughout the system properly. Your air conditioning unit could freeze over, or it can cause your heat pump to freeze.

There are several tell-tale signs that your AC coils need cleaning, including:

  • You’re getting higher electricity bills.

  • Your home doesn’t feel as cool as it usually does.

  • Your AC unit is running longer than usual to cool your home.

  • Your home is more humid than usual.

  • The coil is covered in frost while running.

High humidity is one of the most common reasons for air vents to sweat or produce condensation. When the cool, dry air from your HVAC unit meets warm and moist air in your home, it will cause condensation. Insulating your ductwork can help prevent this. If you live in a very humid region, a dehumidifier can also help.
