"Came home at 5:30 after working all day to find my central air unit not working & my house at 87 degrees. With 2 small children - one having asthma, I panicked. Kenny came right out and within an hour had my unit back in business. Even checked my furnace and tested my unit to make sure everything was running the way it should. Super friendly & reasonable! 10/10 would recommend!"

"Sean Gilhooly was excellent! He was able to repair my Fujitsu ductless mini splits when other companies said the entire AC would have to be replaced. Sean saved me from having to spent over $10,000! He was able to find the leak in the refrigerant pipping, replace the part, test the system, and put new refrigerant in the system. He was efficient and reasonably priced. If I have a need for AC service in the future, Sean will be the guy I call. I highly recommend FinMar Comfort, LC for AC needs!"

"Pete and Isaiah did a wonderful job. They were here close to 6 hours dealing with duct work and dryer vents in my old (1840) house. Also cleaned the airconditioner condenser. They educated me about all the tasks they were working on, responded to my questions and showed me the result of cleaning they had done. I feel really good about the work they did and heartily recommend Duct Kings. Dottie"

"Excellent Service! I highly recommend the Capitol Region Plumbing and Heating Services LLC! Avi, and Sean came to my home immediately when I needed their help with bathroom plumbing and a water pump system. They were courteous, knowledgeable, and thoroughly evaluated the problems. Their excellent assessment and quality of work were evident as I looked at their pictures of before and after replacements of PVC pipes for main sewer lines, sink and shower drains, and water lines for the toilet. Also, Avi and Sean installed a new well pump and pressure tank system. They even came to my home on a holiday to assure me that I'd have water. As true professionals, Avi, and Sean are efficient, punctual, and reputable. Their work ethic is commendable and gracious manners are exceptional. This was an incredible plumbing service that everyone expects and appreciates!"

Heating and Air Conditioning questions, answered by experts

While "dry" mode on your AC can help reduce humidity levels to some extent, it may not be as effective as a dedicated dehumidifier, especially in areas with extremely high humidity or larger spaces. Dehumidifiers are specifically designed to remove moisture from the air more efficiently, making them a better choice for tackling persistent humidity issues.

Some AC filters, known as reusable filters, can be cleaned and reinserted. Most AC filters, however, are disposable and cannot be cleaned. 

Water buildup in your HVAC system is a cause for alarm. If water accumulates in your ductwork, it can drastically lower your home's air quality and create safety hazards. These risks include mold growth, damage to your HVAC system, and attracting pests that are seeking water into your ducts. Proper insulation and sealing of ducts can prevent this, and regular inspection and maintenance can address water damage problems before they become too severe.

Yes, ventless portable air conditioners exist, and not all standard portable air conditioners must be vented through a window.

Ventless portable units, often called evaporative coolers, do not have exhaust hoses. They use a water reservoir and a cooling pad to add moisture to the air, making it feel cooler. These units work best in dry climates because humid areas cannot absorb much additional moisture.

For standard portable air conditioners that do require venting, a window is not the only option; they can also be vented through a door, wall, or ceiling. However, it is essential to vent these units properly. Running a standard portable AC without venting it is counterproductive because it needs to expel heat to cool the room. Failing to do so will only increase the room's temperature.

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.
