"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."

"Scott came out and diagnosed the problem with precision and skill. Unfortunately the supply place for the parts closed early yesterday for Black Friday. He went there early in the morning and came back and fixed our furnace quickly on Saturday at no extra charge. Excellent Customer Service and work. Highly recommend to All. Scott is a true professional."

They were punctual,polite and followed social distancing protocols.They assessed the home and cleaned the air ducts quickly and efficiently.

"My AC was shot, dead. I had three objectives for my search; well, done, well priced and quick. Jason from SM contacted me almost immediately after I hit send on my Home Advisor request. That was Tuesday night. He came to my house the next morning provided a competitive quote (I needed AC but bought an entire system). It is Friday at 5:29 PM 90 degrees outside and 74 in my house, the job is done. Brian and Steve showed up for the install at 8:00 AM and were great. Thanks SM Mechanical and Home Advisor."

Air Conditioning questions, answered by experts

Replacing an HVAC system does not always include new ductwork. The decision depends on the condition of your existing ducts. If they are in good shape, correctly sized for the new unit, and meet current standards, they can often be reused. However, if the ducts are damaged, poorly designed, or improperly sized, they will likely need to be replaced or upgraded to ensure the new system operates efficiently. An HVAC contractor will assess your ductwork and recommend the best course of action. Typically, ductwork is purchased separately, and a full replacement will add to the overall project cost.

You can buy R-22 refrigerant for your home air-conditioning system through your local AC repair specialist, who can also refill your R-22 system as needed. You may find that the cost of R-22 has gone up due to shortages as the EPA banned this refrigerant. Ask your pro to inspect your system for any leaks or issues.

The cost to repair an air conditioner averages around $350 to $450, but the price can range from $100 to over $3,000. The final cost depends on the type of air conditioner, the extent of the damage, and the specific parts that need replacement. For example, repairing a window AC unit typically costs between $100 and $250, while central air conditioner repairs can range from $300 to $3,000. A simple fix like replacing a dirty filter might only cost $10 to $50, but a major issue like a broken compressor could cost around $2,000 or more, potentially making it more cost-effective to replace the entire system. Due to the need for specialty tools and handling of refrigerants, repairs more complex than changing a filter are best left to a professional.

You should plan to change your AC unit's filter every one to three months, depending on the manufacturer's recommendations. You should also clean the coils at least once per year, but if you have pets or someone in your household has allergies, you might need to clean them more often. Fortunately, many pros will clean the coils and change the filter for you during an inspection, which you should schedule once or twice per year.

Yes, technicians check refrigerant levels, loop performance, and system calibration for peak efficiency.
