"HD MECHANICAL! I don’t even know where to start, Chris and his team were went above and beyond when doing work at my house. They were honest and and caring which you don’t see from a lot of companies now a days. My wife and i weren’t sure which direction to go in as far as picking a unit to the whole installation process and what we would need. They walked us through it all and were very comforting as they explained every step of the way. I will 10/10 use them again and recommend it to anyone who is needing A/C and heating!"

"This company was professional, expedient, courteous, and helpful from start to finish. Not having any experience with HVAC, they explained what was needed and why, they helped me with permits and testing as well as accommodating the requirements if my HOA. I highly recommend this company,"

"Pennies are the best. They replaced our central AC and our home heating system about 5 years ago. After that we have found the service to be exemplary! they answer the phone when we call them and they even come out on weekends! I have been so please with them, especially in these days where service is not a priority for companies. If you live the the AV then I would strongly recommend you use Pennies for your heating and AC!"

"It was installed with a kink in the condensation hose and was not aware that it leaked under our hallway wood floor. This was June 2022. I paid to have a leak detection company come out and say the floor was OK. In August 2022, we ran HVAC for a couple of days during the heat wave and water came out of the HVAC unit, ruining our hallway wood floor. It is 10/29/2022 and we still have not heard from their office on how they are going to fix our floor."

"Outstanding. Duane is the best HVAC professional I've ever worked with. He thoroughly explained the HVAC process and standard yearly preventative maintenance requirements. He also gave me a quick tutorial about my particular A/C unit and explained how to spot any early signs of malfunction in order to prevent future expensive repairs. Top notch, highly recommended."

Heating and Air Conditioning questions, answered by experts

Ceiling fans can be a great way to cool your home without the expensive utility bill of running an air conditioner. Plus, ceiling fans can sometimes run in both directions, pushing hot air down in winter and pulling cold air up in summer. With that said, air conditioning might be the only thing that helps if you live in a very warm climate.

You might notice that your air conditioner isn’t running as effectively as it once did. Specifically, your AC unit could take longer to cool your home, or it might struggle to remove humidity from the air. Higher utility bills and hissing sounds coming out of your AC could also indicate a leak.

DIY is possible for basic cleaning. Professional services handle advanced maintenance like recharging the refrigerant.

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.

They can, but it’s not as common. Window AC units are much smaller than whole-house systems and less likely to develop refrigerant leaks or similar issues. As a result, you will rarely need to add a new refrigerant, limiting overcharging problems. However, it’s still important to leave refrigerant management in the hands of professionals when window units need work.
