"Heat pump actually needs to be replaced. Tech showed me video and testing he performed. And why my heat pump was not working. Got up to a cold house this morning. Tried everything I knew to get the house warmer. Called ARS, the scheduled tech and he showed up the same day. I will have to wait for new heat pump to come in. I am satisfied with service so far."

"William brought his best HVAC Techs to our home. He listened to our description of the problem. He and the Tech Bob accessed our attic to directly examine the furnace in operation. Thru it they found the problem source. They explained our options. They ordered the parts, returned ASAP. Installed the new parts, adjusted them appropriately. We are now comfortable, and happy. Go Shamrock! We like their wprkmanshop, thanks guys."

"We've been using this HVAC company at our restaurant, Curry and Noodle in Winston-Salem, and we couldn't be happier. Running a busy kitchen means our heating and cooling systems take a real beating, and Chris has been nothing short of amazing. He shows up on time, communicates clearly, and always makes sure everything is running perfectly before he leaves. It's rare to find someone who treats your business like it's their own — but that's exactly how Chris makes you feel. Highly recommend to any business owner in the area looking for reliable, honest HVAC service!"

Heating and Air Conditioning FAQs, 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.

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.

Absolutely! You can seriously improve the overall value of your home by maintaining high-quality, compatible systems for heating and cooling. Potential buyers will love not having to worry about getting a new HVAC unit for 15 to 20 years and will pay more for it. For maximum efficiency and cost savings, replacing the furnace and air conditioner at the same time, when possible, gives you (and potential future buyers) reliable comfort and modern convenience.

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.

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.
