"I had a great experience with Nate. He was extremely knowledgeable about A/C systems and was far more well-versed than many other companies in the area. He took the time to explain everything clearly, answer my questions, and make sure I understood the issue and solution. Nate was also very friendly, professional, and informative throughout the entire visit. I truly appreciated his expertise and excellent customer service. I would highly recommend Nate to anyone needing HVAC service."

"Patsy Cicala has so much knowledge and experience and was able to dismantle the mess made by the plumbers and correctly configure and install the filter system. It is working perfectly now and we are enjoying pure filtered water. Mr. Cicala really saved the day! In addition to being experienced and competent, he is reliable, respectful and pleasant to work with. I definitely recommend him and will contact him again for any projects or services needed in the future."

Heating and Air Conditioning questions, answered by experts

Air filters with a high MERV rating, 11 or above, shouldn't cause airflow problems in most residential systems. However, the airflow can be restricted in some HVAC systems if they aren't designed for high MERV ratings. If in doubt, a local duct installer should inspect your ductwork so that you know what your system can handle.

Evaporator coils in an HVAC system typically last between 10 and 15 years, which is roughly the same lifespan as the entire AC unit. The longevity of the coils can be affected by usage frequency, environmental conditions, and how well they are maintained. Regular maintenance, such as cleaning and inspections, can extend their durability. If the evaporator coil fails in an older air conditioner, it may be more cost-effective to replace the whole unit rather than just the coil.

Deciding whether to replace just the AC coil or the entire system depends on the age of your unit and the overall cost. Replacing a coil is less expensive than a full system replacement, but it can still be a pricey repair. If your HVAC system is relatively new and still under warranty, or if the replacement cost is significantly lower than a new system, replacing the coil can be a worthwhile investment that restores efficiency and extends the unit's life. However, for older systems (nearing the end of their 10-15 year lifespan) or those with extensive damage, it is often more cost-effective to replace the entire AC unit. Mismatched coils in an older system can lead to inefficiency and future breakdowns, so a full replacement ensures optimal performance and avoids further costly repairs.

The compressor is the heart of your AC system and is one of the most important parts required to keep it functioning properly. If your AC unit is making a popping, banging, clanging, clicking, or screeching sound, it could point to a problem with the compressor. If the unit is physically vibrating, that can also be an indication that your AC compressor is going bad.

While many states do not have specific licensing requirements for HVAC companies, your local city or county might. It's always a good idea to check local requirements online and use a tool like Angi’s contractor license lookup to confirm that the company you’re considering is licensed. Regardless of licensing, you should always ensure the company you hire is fully insured to avoid potential lawsuits if a technician is injured on your property. Additionally, it is recommended to check if the company holds third-party certifications, such as North American Technician Excellence (NATE) certification or R-410A certification, which qualifies them to work with HVAC refrigerants.
