"We noticed a foul smell coming from one of the vents in our HVAC system. We turned the system off and called AC Dave. Dave sent Justin and James to troubleshoot the problem. They quickly found a tear in one of our ducts--and the remains of a dead rodent. They cut open the duct, cleaned it and resealed it. We had heat again, about an hour after they arrived. Very fast and competent service."

"Great. My daughter contracted Air Duct Professionals to do her home. James, the technician, was professional, knowledgeable and did a quality job. I contacted Air Duct to do my home and requested James. James arrived on time and did an excellent job. He also helped me with a leak with my HVAC Condenser and diagnosed and fixed the issue."

"A nice guy turned up on time to check my aging HVAC system to see there are any problems needing attention. He checked everything and gave me a clean bill of health. Other HVAC contractors have always presented me with a list of vague problems with a recommendation that I renew the whole system at $20,000 plus. It was refreshing to find someone honest for a change."

Heating and Air Conditioning questions, answered by experts

Because of the improved efficiency, ACs with higher SEER ratings tend to cool down your home better than models with a lower SEER. Higher-SEER AC units have a higher cooling capacity and a lower energy demand, meaning they may help cool your space faster without running up the electricity bill.

The cost of R32 refrigerant is about the same as the cost of R410A refrigerant, the most widely available type of refrigerant today. However, R32 systems use about 20% less refrigerant than R410A systems, making the refrigerant less expensive overall.

High humidity is one of the most common reasons for air vents to sweat or produce condensation. When the cool, dry air from your HVAC unit meets warm and moist air in your home, it will cause condensation. Insulating your ductwork can help prevent this. If you live in a very humid region, a dehumidifier can also help.

Most HVAC service calls include diagnostic fees, which could include checking on a specific issue you’re experiencing or running through a routine inspection checklist. If you called for a particular problem, the service call will also include an estimate to fix the issue, including materials and labor. Depending on your HVAC technician and the service you requested, you might also get a general inspection of your system components to ensure everything is working as intended.

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.
