"Great Experience. I was concerned about the 22 yr age of our air conditioner able to keep working and wonder if a long wait time to get a product shipped like refrigerators last year, I called for a quote and within a week it was installed and working! Installers worked tirelessly until their work was done, clean and neat!"

"Liberty did a fantastic job identifying and rectifying airflow problems with our existing Hvac system that was installed less than two years ago by another company. They were punctual, responsive and incredibly knowledgeable. I highly recommend them."

"I highly recommend AAA home services. They installed a brand new HVAC system and the entire process was trouble free every step of the way. I have had them out to service the system twice a year and the scheduling to do so is easy and the service has been excellent. AAA home services has always communicated well and I have had them do exceptional plumbing work including the installation of a hot water heater. Thank you AAA home services."

"The 3 Mustache Pledge! Schraer Heating and Cooling deserves every bit of praise I can give! I called them about a worrisome noise coming from my system — one that I could only describe through a few rather vague and comical sound effects. Despite my less-than-technical explanation, their technician quickly understood exactly what I meant, found the issue, and had it fixed in no time. Their professionalism, responsiveness, and ability to solve the problem so efficiently (and with good humor!) made the whole experience stress-free. I’m so grateful for their excellent service and expertise. Highly recommend Schraer Heating and Cooling to anyone looking for honest, skilled, and friendly professionals! I will definitely keep my maintenance agreement in full force and effect!"

"Had several quotes for the replacement of my water heater. Hosack plumbing was in line with most of the quotes but they included all the extras that some companies did not. Darrin arrived on time and was friendly and did a fast and professional job. I even had a small leak in one of my cold water pipes that he repaired and he also replaced my gas exhausts pipes. both of these where not part of the original quote but where done for me at no additional charge. I would highly recommend this company for great service and a fair price."

"I was having some serious issues with my HVAC system and attempted a couple of DIY solutions. When it comes to serious wiring and hookups of electrical components, I tend to call in the professionals. Arrow Mechanical was fast and convenient and did a very thorough job. They even helped with some of the more advanced electrical work inside my HVAC system to get everything up and running perfectly again! I feel very confident that everything is working properly today! Would absolutely recommend Arrow Mechanical again!"

Heating and Air Conditioning questions, answered by experts

There are many recognizable symptoms of AC compressor failure. They include loud banging noises, hot air being continually circulated in your home despite running the AC at full blast, uneven airflow and cooling, and electrical issues like constant surges due to the compressor working overtime. While some of these symptoms, like uneven cooling, can have other root causes, they are common indicators of compressor problems.

When your HVAC technician mentions recharging your home AC unit, they’re referring to the process of topping off the unit with refrigerant, so the levels are properly maintained and pressurized. Normally, a properly functioning AC unit doesn’t need additional refrigerant, but AC units can develop leaks or other problems that decrease the amount of refrigerant needed.

For the most part, you should leave your AC fan in “auto” mode so that it only runs during a heating or cooling cycle. Keeping it in this position uses less energy, which equals lower utility bills. However, there are some situations where it’s better to leave your AC fan on, including if you have allergies or there are lots of people in your home.

Trick question: There is no difference between an AC and a furnace blower motor. Whether you have central air and heat or just one of these, the same blower motor carries hot and cold air throughout the ductwork in your home. Certain systems may have separate blower motors for the AC and furnace, but each serves the same function.

While an air conditioner can temporarily run with a dirty filter, it is not recommended as it will not work efficiently. A dirty filter forces the system to work harder to circulate cool air, leading to reduced airflow, increased wear and tear, and higher energy bills. This added strain can cause the air conditioner to overheat or fail prematurely. Furthermore, a clogged filter may allow dust and dirt to accumulate in your ductwork, negatively impacting air quality. It is more cost-effective to clean or replace filters regularly than to pay higher utility bills and risk needing to replace the entire AC unit.
