"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."

"Ductz of the Upper Bay Region cleaned my ductwork today. The team was professional and friendly. The cost was stated in advance as a firm price and not an estimate. They took before and after pictures which I found very helpful. The owner and his team went above and beyond to suggest ways that I can best maintain my A/C system to minimize the need for cleanings in the future. I recommend them highly."

"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."

Heating and Air Conditioning questions, answered by experts

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.

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.

While it is possible to add Freon to your AC unit yourself, it is not recommended. In fact, the U.S. Environmental Protection Agency (EPA) prohibits the handling of Freon without a license. Freon is a dangerous gas that can cause irreversible damage to your AC or yourself if not installed correctly. It is worthwhile to hire a professional to add Freon to your AC.

Yes, AC coil cleaning is definitely worth it. Cleaning your AC coils ensures your AC unit will function efficiently for the long term. Dirty and grimy AC coils make your unit work harder to cool your home, resulting in higher electric bills. Additionally, having your coils professionally cleaned regularly will reduce the possibility of extensive maintenance and repair costs.

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.
