If you need a plumbing, heating, or air conditioning repair in Skagit County, the experienced and knowledgeable team at CPI Plumbing & Heating can help! However, you may have questions about your situation, and you might be searching for answers before you make the call. Here are a few of the most commonly-asked questions we receive about our business and the answers we can provide you.
Our founder, Steve Olsen, sold the company to three of his long-time employees, one of which was his son. This same leadership group has led the company since 1990.
We offer our services at regular rates: Monday to Friday from 8 a.m. to 6 p.m. However, we also offer after-hours emergency services at our emergency rates: Monday to Friday from 6p.m. to 8 a.m. and Saturday and Sunday all day, because sometimes problems don’t wait until business hours to spring up. Our business office is open from Monday through Friday from 8 a.m. to 5 p.m.
The price of a service call varies on a per-job basis, so you’ll need to call our office to get a specific answer. We do not charge on a per-hour basis, we charge per-job, so you won’t have to worry about surprise overtime fees or other costs that other companies might throw at you.
Yes. When our technician arrives on-site and conducts an inspection of the issue, they’ll give you a written price quote.
We offer a complete range of plumbing, heating, and air conditioning repairs, replacement, installation, and maintenance services for residential and commercial applications. We offer drain cleaning, leak detection and repair, water heater repairs and replacements, backflow certification, re-piping services, video pipe inspections, air conditioner and heater inspections and diagnoses, system replacement, heat pump repair, blower motor repair, and much more.
We’re so confident you’ll be completely satisfied with the services you receive that we back up all our repair work with a 90-day warranty and all our replacement and installation work with a full one-year warranty! If anything goes wrong with our solution during that time, we’ll come fix the issue again at no cost to you.
No, you don’t. As long as we can access the systems we need, we can perform all of the necessary work without you needing to be present! We are both licensed and fully-insured with a $1 million per claim liability policy, and we have an A rating with the Better Business Bureau in order to give you the confidence of knowing the job will be done right if you can’t be home while we’re there.

    Very polite.Worked in terrible conditions no complaints about the situation.I my opinion it was a management mistake to send a tech out at night in a rain storm to unclog a storm drain.He worked for hours with no success.Del Chasteen Pres.VRV HOA

    Arrived on site per customer request, when I arrived the customer informed me that the furnace was producing no heat and the blower was just running. Offered customer pricing to replace the furnace as well as to do a diagnostic. Customer elected to go with the replacement. Let customer know we would be in contact with them shortly to schedule the install. Gave customer 2 space heaters for temporary heat and showed them how they work.
