"From start to finish it was a very positive experience. Shane explained everything and answered all my questions when he came out to give me an estimate on the project. Brandon and Brian showed up on time, completed the job in a timely manner and cleaned everything up when they were done. They showed me how to operate my new mini split AC system before they left. Shana was also very helpful when I called the office. The project turned out great. I would highly recommend Onofreo Home Comfort Systems."

"Tom Mull talked to me on the phone and told me there was a 60% chance that he could fix it cheap. Then Mr. Mull came out and looked at it in person and told me that there was a cheap fix, and that there was a 50% chance that this would fix the problem for a while, so I told him to go ahead. Unfortunately, when his service tech came out to look at the oil tank, he told me there was a 0% chance that he could fix it cheap and that I needed a new oil tank. I did wind up getting a new oil tank, but not from Mull Brothers."

Air Conditioning questions, answered by experts

If your AC condenser is nearing the end of its life, it might leak fluid or make loud or unusual sounds (like grinding or hissing). You might also notice that it isn’t heating your home as evenly or effectively as it once did. Also, an aging condenser will have to work harder to cool your home, which may force it to use more power and drive up your utility bills.

Most experts recommend getting three to five HVAC quotes from licensed, insured, reputable local heating and cooling companies. Getting multiple detailed HVAC quotes (but not too many) lets you compare the equipment, services, and prices of several contractors without being overwhelmed by options. It can also let you see if one contractor’s prices are much higher or lower than the others and give you a chance to ask for clarification. That way, you can weed out any contractors who aren’t providing quality services or materials and find the company that best meets your budget, quality requirements, and long-term goals.

There are a few reasons your AC is running but not cooling your room. Thermostat issues and dust and debris, which can clog your system, are common problems. It could also be a broken component, such as a compressor, blower fan, or evaporator coils. You’ll need to call a pro to diagnose the issue.

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.

When an evaporator coil becomes faulty, it can result in various problems within your HVAC system. These problems could include reduced cooling or heating capabilities due to ice formation and obstructed airflow, along with increased energy consumption and higher bills. Additionally, a damaged coil may lead to refrigerant leaks, which are environmentally harmful and decrease overall system efficiency.

Ultimately, if not addressed right away, a bad evaporator coil can even lead to a complete failure of your HVAC system. That’s why timely repair or replacement is crucial to maintaining your family’s comfort and your HVAC’s efficiency.
