Your Trusted Home Comfort Experts
CPI Plumbing, Heating, Cooling & Electrical

With decades of expertise, we offer top-tier heating, air conditioning, plumbing, electrical, drain, and generator services.
My Furnace Stopped Working. What Should I Do?
First, check that your thermostat is set to “heat,” the batteries are fresh, and the furnace filter isn’t clogged. Make sure the furnace switch is on and the breaker hasn’t tripped. If you still have no heat, give us a call. We offer after-hours emergency service on weeknights and all day on weekends, so you won’t be left in the cold.
How Do I Know If My Furnace Needs to Be Replaced?
Common signs include a furnace that’s more than 15 years old, frequent repairs, rising energy bills, uneven heating, or strange noises and smells. Our technicians can inspect your system and give you a written quote so you can decide whether a repair or a replacement makes more sense.
What Should I Do If My Pipes Freeze?
Turn off your main water supply right away and open the affected faucet to relieve pressure. Never use an open flame to thaw pipes. Then call our team. We can safely thaw the line, check for cracks or leaks, and help you prevent it from happening again.
What Services Do You Offer?
We offer a complete range of heating, plumbing, electrical 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, repiping services, video pipe inspections, air conditioner and heater inspections and diagnostics, system replacement, heat pump repair, blower motor repair, and much more.
Do You Guarantee Your Services?
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.
Do I Have to Be Home When You Arrive?
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.
