"Frank and his team did an excellent job from start to finish. He arrived the same day I requested an estimate and replaced my 30 year old system 3 days later. The new HVAC is wonderful. No mess or damage, great price, and great quality you would expect from a small privately owned company."

"After signing a contract on a Monday for a specific brand of heat pump they texted me Thursday morning, 24 hours prior to installation to announce they were changing the brand being installed. After a number of calls I had to agree to a substitute brand. Otherwise they told me it would be 4 weeks to get the original brand."

"I recently had a HVAC and water heater installation by Carroll Mechanical, Cris Lopez and his team. They were very respectful of my home and professional throughout the install. I am grateful and appreciative of working with the owner on deciding the HVAC unit to be installed. I found him to be the consummate professional, a person of integrity, transparent, responsive to my questions and willing to work with me to gain my business. I highly recommend Carroll Mechanical."

"I used Regal Duct Cleaning today. Our home is 60+ years old. We have only lived in it for 20 months and there was more dust, dirt and webs than I had ever imagined. Julius and his crew arrived at the scheduled time. He was extremely professional. We went from room to room looking at every every vent, cold air return. His crew worked for five hours, cleaning the ducks, dryer vent and installed a UV light. I highly recommend Regal Duct Cleaning . I will definitely use them again! To see the before and after pictures was a real eye opener. Great Job!"

"I hired Best Air Quality and Restoration to clean my dryer vent. I was very pleased with their level of professionalism. All my questions were answered without hesitation. The price was fair and affordable. Dennis, the technician notified me of his expected arrival time. He was very nice and pleasant. Dennis explained what the job entailed and completed the job within an hour. There was no excess lint or debris in my home to clean. I would recommend Best Air Quality and Restoration to others to experience for themselves. I intend to use other Best Air Quality and Restoration services again in the near future."

Heating and Air Conditioning questions, answered by experts

No. Evaporator coils are designed to work with specific refrigerant types, and they are rated by what kinds of refrigerant they use. It’s indicated with an “R” code. It’s important to match your evaporator coil and refrigerant or your system will not work properly. An AC technician can tell you what type of refrigerant your system needs and what evaporator coils will work with it.

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.

Ideally, an AC system should never need more Freon (a popular refrigerant) because it circulates in a closed loop. However, refrigerant leaks are not uncommon and may occur gradually over 5 to 15 years. If your system has a leak, it will need to be topped up in a process known as an AC recharge. Signs of a refrigerant leak include weakened AC performance, increased humidity in your home, higher utility bills, and a hissing sound from the unit. The cost of an AC recharge will depend on the size and type of your AC unit, as well as the type of refrigerant it uses.

You will enjoy greater energy efficiency and save on your annual energy bills, with new, modern HVAC systems using 30% to 50% less energy than older models. Upgrading your HVAC system is also a great way to embrace new technology, such as smart thermostats, lighting, fan speed, and humidity from your phone or tablet.

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.
