The only hourly rate our plumbing and HVAC company has is for sewer cleaning. All plumbing, HVAC, and sewer/septic repairs and installation are given to you in writing before work begins.
If you choose not to have our HVAC and plumbing company do any work for you, we only collect $125 for the time of our service professional. When our service professional leaves, you will have in writing how much the investment will be as well as how the work will need to be completed.
As one of the top local septic system companies, we recommend having your septic tank pumped regularly. Every residence is different, but we recommend going no longer than three years.
Our plumbing and HVAC company office is open from 8:00 AM – 4:30 PM. We have after-hour services upon request and for true emergencies. Our phones transfer to our answering service.
