"They destroyed the whole pipes that caused flooding to my neighbors. The water was off and every other day we need to go out to the street to turn it on. This company denied the responsibility but later reimbursed me for the first leak repair after employee acknowledging doing partial work. This project aims to address and fix the extensive leaks. Must be completely replaced, cause of leaks appears to be from over heating of the copper as locations are at ALL connections and bends in the pipe, too much to patch. You can contact me to this phone number: 9(16) 857-5652"

"Tech said that the Freon leaked out and that the compressor burned out because of it. Quoted $4800 to replace compressor and recharge, or $7,000 for a new AC unit. Got a second opinion and hired a handyman. Turns out the breaker was tripped and needed some fiddling with. AC works great now. Can’t believe they were going to lie about what was wrong to replace the whole AC. Just because it was an old unit. Get a second opinion for them if they tell you something similar."

"Called this company for their $77 dollar, which they advertised with a flyer, for a tune-up and cleaning for my heating system. They are a Hayward company and I was told that our Castro Valley home was not in their service area. I bet if I called to buy a new heater they would be out in a day."

Warning signs include rooms that never seem to reach comfortable temperatures, unexplained increases in utility bills, or unusual sounds when your system operates. You might also notice excessive dust accumulation, visible damage to accessible ductwork, or musty odors coming from vents. Addressing these symptoms promptly results in simpler, less expensive repairs.
Rigid ductwork can last up to 25 years with proper maintenance, while flexible ductwork lasts 10 to 15 years, sometimes up to 20. Factors affecting your ductwork’s longevity include installation quality, environmental conditions, and HVAC maintenance frequency. Regular professional ductwork inspections can identify potential issues before they compromise the entire system.
Replacement becomes worthwhile when your existing system has extensive damage, is over 15 to 20 years old, or requires frequent repairs. New ductwork can improve HVAC efficiency by up to 20%, potentially reducing energy costs significantly. The investment often makes financial sense when repair costs approach half the price of a new installation or when air quality concerns become persistent.
Most standard repairs require four to eight hours of professional time, though complex situations may extend to multiple days. Factors affecting the timeline include accessibility, repair complexity, and whether additional services like wall repair are needed. Your contractor should provide a time estimate before beginning work, with most routine repairs completed within a single day.
