Why does it seem that the worst plumbing or air conditioning problems happen when you least expect it? Your AC fails in the middle of a record heat wave, you find a water leak right as you’re leaving for vacation, or your heater stops working in the dead of winter. Whether you need routine maintenance to prevent such issues in the first place, or a trusted technician to handle a plumbing or air conditioning emergency, you can trust the team at Five Star Plumbing Heating Cooling.

"Today I experienced the worst encounter with 5 star heating plumbing in air.The technician that came out was incompetent confused he told me thar my control damper motor was bad the other was good and my zone control board was good .... In which to replace a control damper motor is not as much as of a hundred or two hundred dollars then he tells me because they don't carry the honeywell motor that I would have to replace my entire system and it will cost me $4279.....this must be a scam....please beware"

"I made an appt with them for Wednesday from noon to 2. They no showed and didn’t bother to call. I called back Friday and they agreed to come out right then. However, the truck didn’t have enough to pump my entire septic and they said they would come out first thing Monday. They no showed again on Monday. Four days later they tried to contact me to reschedule. I refused at that point. I can’t be kept waiting for 2 weeks for whenever they feel it is convenient for them…if you make an appt, keep it!"

"On 6/1/2022 a technician shows up for a water leak under my home, the tech was friendly, on time, and professional, in appearance. I point out where the leak is, after 30 minutes he says the main pipe is probably plugged which created additional weight, possibly stretching supports and as a result the shower drain pipe had been disconnected. He said he would write up a quote, and I was shocked to find it was for 10k. I refused service but asked for a detailed write up for what needed because I was paying an $89.00 Regular Service Fee (29-89) and another fee, MISC level 1 1 which was $97.00 for god knows what. Here is the write up I received from the technician.(More commentary below) "END TASKS*/ upon arrival customer had leak in crawl space and shower has disconnected the reason this disconnected is due to the weight of the sewer line this line is full of water and when wisher is ran it backs up out of this line causing a leak this line has fallen in ,multiple spots and is sagging in multiple spots this is abs piping. I gave options to repipe both bathrooms and then after run camera to locate septic tank. The reason customer is not backing up into house is because everything comes out this shower drain. I gave customer the options for repipe he did not want to continue with any work there is not a cleanout outside for me to camera this line and cannot locate where line exits home for ability to locate septic tank. Options were provided customer did not want to proceed with any work inspection fee was charged. Repipe and camera locate septic Camera Locate Septic Tank from Clean Out 1x $369.00 2 bath/kitchen/laundry drain only L1 1x $9,552.00 Deposit on Ben Society Agreement 1yr $99.00 Start date: 06/01/2022 Subtotal: $10,020.00 Discount: - $315.00 Tax: TBD $9,705.00 I asked how long this work would take and was told 2-3 days. Simple math tells me I could pay a guy 100$ an hour for 97 hours, or 2 full weeks and then some at that rate. I thought to myself, ok, he does not want to do the work so he priced himself out. I am ok with that, but the business owner should be made aware of what is going on and cut these guys loose because there are plenty of other options out there. I am also shocked at the lack of detail for pricing, for 10k I need know specifically what is being done, on a line by line basis. After all, I paid almost 200 dollars and I would like to think I am owed that much. One last detail, I did call in and spoke to "Angel" who said she would relay my concerns and that someone would be calling me back. I am not holding my breath."

FAQs for tankless water heater installation projects in Spartanburg, SC

Professional flushing services for tankless water heaters run about $200 per visit. This essential maintenance procedure eliminates mineral deposits from critical components, particularly the heat exchanger. While homeowners can purchase DIY flushing kits for $50 to $100, professional service offers the advantage of thorough cleaning with proper techniques. Professional maintenance also includes inspection of additional components that might need attention.

Industry experts and manufacturers recommend annual maintenance for tankless water heaters, with more frequent service (every six months) for homes with challenging water conditions. This regular attention prevents efficiency losses and extends the unit's operational lifespan. Watch for warning signs like reduced water temperature, inconsistent performance, or system error codes that might indicate maintenance is needed sooner than scheduled.

Neglecting regular maintenance allows mineral scale to accumulate within your system, restricting water flow and reducing heating efficiency. This forces your unit to work harder, consuming more energy while delivering less satisfactory performance. Over time, this strain can lead to component failures, inconsistent water temperatures, and premature system replacement. Additionally, most manufacturers require documentation of regular maintenance to honor warranty coverage for major components.
