"Wonderful, punctual service and very professional! We were not expecting AC issues In our newly constructed two-year-old home...Dan came out and not only got the AC going but explained thoroughly what was causing the issue and the French drain design of our home… He suggested a long-term solution and after allowing us time to investigate, promptly resolved the additional problem of drainage in our crawlspace. All at a very reasonable price.We were impressed and highly recommend this company!"

"I would highly recommend Hometown Heating and Air LLC. Zach and Harrison were very professional and there work ethic Is unmatched. They were very helpful in helping us make decisions in what systems would be best based on our needs. They explained the process and there communication was on point. They went out of there way and worked long hours to get our new HVAC system installed in a very timely manner. My wife and I were very impressed and canâ t say enough to thank them for all that they have done. Our system has been installed for a couple of months now and we have seen a significant drop in our power bill. We had them install the Bosch 18.5 Seer and it has been awesome. It exceeds all our expectations. Thank you Hometown Heating and Air for making this such a positive experience. Highly Recommend!ed!!!"

"I had a great experience with Pollock HVAC! Alex and TJ are both professional, friendly, knowledgeable, and incredibly helpful throughout the entire process. They took the time to explain everything clearly, answered all of my questions, and made sure the job was done right. It’s refreshing to have technicians who genuinely care about their work and their customers. TJ and Alex were courteous, respectful, and efficient, and I really appreciated their attention to detail. I highly recommend Pollock HVAC and would definitely request TJ and Alex again in the future. Great service from start to finish!"

Air Conditioning questions, answered by experts

As mentioned above, not all HVAC Schrader valves are necessarily the same. While the valve core and pin or spring size on Schrader valves used for HVAC are generally similar, the valves are not all universal and interchangeable. The size of Schrader valves varies depending on whether it's used in an air conditioner, bicycle tire, or motor vehicle tire.

The average life span of an HVAC system is 15 to 20 years. Even if your old air conditioner is still functional, it isn't as energy-efficient as a newer system (especially one with an Energy Star designation). Older HVAC systems aren't as efficient, and the 10-year mark is when you should start making full system replacement plans. Twenty years in, that plan should be well underway rather than waiting for the unit to die.

On a summer day, expect your AC to run between 12 and 16 hours. However, this time frame depends on just how hot it is outside and the comfortable temperature you’re hoping to maintain indoors. Assuming the size of your AC is appropriate for the space you’re trying to cool, it shouldn’t be a problem for it to work this many hours.

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.

To keep your air conditioner in good working condition, you should have it serviced by a professional at least once per year, ideally in the spring before the cooling season begins. If your AC unit is 10 years or older, consider servicing it twice a year (once in the spring and once in the fall) to catch potential problems early and help it reach its full lifespan. During a service visit, a technician will inspect, clean, and replace parts as needed. Regular maintenance helps avoid costly repairs. As a DIY task, you can also clean the evaporator coils annually.
