About CAL Plumbing & HVAC LLC in Lewiston

Licensed Master Plumber Serving Lewiston and Surrounding Communities

CAL Plumbing & HVAC LLC is a locally and family-owned plumbing and HVAC company serving homeowners and businesses in Lewiston and surrounding areas. As a fully insured contractor holding a Master Plumber license and multiple specialized certifications, we handle everything from routine repairs to complex installations with the technical expertise your property requires.

Our Master Plumber license (License #MS9022762) means you're working with a professional who has demonstrated advanced knowledge of plumbing systems, codes, and installation standards. This credential isn't just a formality—it ensures that every pipe, fixture, and connection meets safety requirements and performs reliably over time. Whether you need a water heater replacement, drain cleaning, or complete system upgrades, you're getting work performed to the highest technical standards in the industry.

On the HVAC side, our certifications cover the full range of systems you'll encounter in residential and commercial properties. We hold a Propane Natural Gas Technician Tank Setter & Pipe Tech license (License #PNT17244), Universal 608 certification for refrigerant handling, and A2L certification for the latest refrigerant types entering the market. These credentials mean we can service traditional systems, work with propane installations, and handle the newest environmentally-friendly refrigerants that many modern units now require.

Being family-owned and locally operated means you're not dealing with a call center or rotating technicians. When you contact us, you're reaching the same team that will show up at your door, diagnose the problem, and explain your options clearly before any work begins.

Technical Expertise Backed by Multiple Certifications

Our combination of plumbing and HVAC expertise under one roof gives you a single point of contact for the two most critical systems in your building. You won't need to schedule separate contractors when a project involves both disciplines—we coordinate everything from planning through completion, ensuring that plumbing connections, gas lines, and HVAC equipment all work together properly.

The Universal 608 certification is required by the EPA for anyone handling refrigerants in air conditioning and heat pump systems. It demonstrates that we understand proper refrigerant recovery, recycling, and handling procedures that protect both the environment and your equipment. The newer A2L certification covers the mildly flammable refrigerants that are replacing older types in many residential and commercial systems—this training ensures we can safely service the latest high-efficiency units entering the market.

Our Propane Natural Gas Technician credentials allow us to handle gas line installations, tank setting, and pipe connections for heating systems, water heaters, and other gas appliances. This specialization is particularly valuable when you're adding new equipment, converting from electric to gas, or upgrading older gas systems that may not meet current safety standards.



We provide 24/7 emergency plumbing and HVAC services because we know that system failures don't wait for business hours. When a pipe bursts in the middle of the night or your heating system quits during a cold snap, you need immediate help from someone who can diagnose and fix the problem correctly the first time.

Family-Owned Service You Can Count On

As a family-owned business, our reputation in Lewiston and surrounding communities is built on every job we complete. We don't have the option of moving on to another market if we deliver poor work—we live and work here, and we depend on word-of-mouth recommendations from neighbors and local businesses who trust us with their plumbing and HVAC needs.



You'll notice the difference in how we communicate throughout the process. We provide written estimates that break down exactly what work needs to be done and what it will cost before we start. We explain your options when there's more than one way to solve a problem, and we'll tell you honestly when a repair makes sense versus when replacement is the smarter long-term investment.

Whether you need emergency repairs, routine maintenance, or a complete system installation, CAL Plumbing & HVAC LLC brings the technical expertise and local accountability you deserve. Reach out today for a free estimate—we'll assess your needs and provide clear pricing before any work begins.
