What Sets Us Apart
Lafferty Heating vs. Other Contractors
| Our Approach | Their Approach | ||
|---|---|---|---|
| Use building science. We use diagnostic equipment to get to the bottom of performance and comfort issues. We never make assumptions. | Swap parts and guess. Without building science training, it’s hard to identify a root cause, which means replacing parts and hoping the problem goes away. | ||
| Prove our results. We measure every new installation with third-party testing tools, so you get hard evidence the job was done right. | Skip the verification. Many contractors don’t carry the diagnostic tools that show whether an installation was done correctly. | ||
| Never cut corners. Our in-house sheet metal laser cutter lets us fabricate duct fittings on demand, so your system gets the right component, not the closest thing in stock. | Work with what’s on the shelf (or in the van). Without fabrication tools, they’re limited to off-the-shelf parts, even when those parts aren’t the right fit. | ||
| Repair before replacing. Our goal is to keep your system running as long as it can. If your equipment can be saved, we’ll save it. | Replace before repairing. Some contractors won’t service a system over ten years old, and will push you to replace it before you really need to. | ||
| Custom solutions. Custom sheet metal and ductwork are our specialty. Complex layouts, tight spaces, and unusual requirements are no problem for us! | One service fits all. Custom work takes time and skill many shops don’t have, so every customer gets the same standard install. | ||

Why Work With Our Professionals
Lafferty Heating’s Difference
Locally Owned and Operated
We’re a small, local business in Cambria and SLO County dedicated to helping other local homeowners and contractors.
Industry Certified
We hold certifications from the National Comfort Institute (NCI) and North American Technician Excellence (NATE).
Building Science-Focused
We perform load calculations before installing every new system to ensure it’s properly sized, and we measure complete performance vitals post-installation.
Code-Compliant Installations
We always pull a building permit for furnace replacements, which many contractors don’t do. This ensures your new system is fully legal and inspected by enforcement officers.
In-House Fabrication Machinery
Our digital design tools and flatbed laser cutter allow us to create complex, intricate sheet metal components that are cut to precision.
What People Think
testimonials
Lafferty Heating corrected an improperly installed hot water heater vent. They performed the job quickly and at a good price
Robert Segal
Friendly and competent serviceman came to do a check up on my heater. He changed batteries on my thermostat, which I wouldn’t have thought of. Went above and beyond and cleaned off my heater surface (of pre-termite fumigation droppings), and even removed a large next from the attic (where heater is located). Best of all, he assured my heater is in good condition and will last quite a while. Good to have this competent company in town.
Connie
We have used Lafferty Heating for many years, for metal fabrication, replacement of a spark arrestor for the chimney, annual servicing of our heater, and couldn’t be more pleased with their service. They are truly a Cambria asset! Thank you, Jeremy, Peter and all, at Lafferty Heating.
