From emergency furnace repair to full new construction installs — Hilliard's has handled every type of heating, cooling, and plumbing job across the Palouse since 1968.
When a Palouse winter hits and your heat goes out, you need someone who picks up the phone and shows up. Hilliard's has been doing exactly that since 1968. We service and install most major brands of gas and electric furnaces, heat pumps, and boilers — and as an authorized Carrier dealer, we're equipped to offer factory warranty options on new Carrier equipment.
Whether your furnace is short-cycling, failing to ignite, producing uneven heat, or simply past its prime, our technicians can diagnose the problem quickly and give you a straight answer on whether it makes more sense to repair or replace. We don't oversell — we've been in this community too long for that.
Annual maintenance is the best investment you can make in your heating system. A tune-up catches small issues before they become middle-of-January emergencies, improves efficiency, and extends equipment life. We offer maintenance for all makes and models, not just the brands we sell.
Pullman summers can push into the 90s, and a failing AC during a July heat wave is miserable. Hilliard's has been keeping homes and businesses cool across the Palouse for decades. As an authorized Carrier dealer, we install and service Carrier central air systems and participate in Carrier's Consumer Choice Warranty program — giving you factory warranty options on eligible equipment.
If your AC is running but not cooling, tripping breakers, making unusual noises, or cycling on and off too frequently, don't wait for it to fail completely. Our technicians can diagnose the issue and get you back to comfortable quickly. We stock common parts and work on all major brands, not just Carrier.
For homes or additions without existing ductwork, we also install ductless mini-split systems — an efficient, flexible cooling and heating solution that's become popular in the older housing stock around WSU's campus neighborhood.
Hilliard's full-service plumbing operation covers everything from a dripping faucet to a complete new construction plumbing layout. We work on homes, commercial buildings, rental properties, and everything in between — serving Pullman, Moscow, and the wider Palouse region.
The older housing stock in Pullman — particularly around College Hill and the historic downtown — comes with its own set of plumbing challenges. Aging galvanized pipes, dated fixture connections, and sewer lines that have seen decades of use require a plumber with experience, not just a parts catalog. We've worked on homes in this town since the 1960s and we know what we're dealing with.
On the commercial side, we handle service calls and new construction for businesses across Whitman and Latah counties. Whether it's a multi-unit apartment building near WSU or a retail buildout, we provide complete plumbing layouts and installation with the same accountability we bring to every residential job.
A clogged or slow drain is an inconvenience. A backed-up sewer line is an emergency. Hilliard's provides complete drain and sewer services for residential and commercial customers across the Palouse — and we have the equipment to handle everything from a kitchen drain to a full sewer line issue.
Older homes on College Hill and throughout Pullman's historic neighborhoods frequently deal with tree root intrusion, deteriorating clay sewer lines, and decades of buildup. We use pipe inspection camera technology to see exactly what's happening inside your lines before recommending a course of action — no guesswork, no unnecessary excavation.
For commercial customers, we offer regular drain maintenance to prevent the kind of blockages that shut down a restaurant kitchen or a multi-unit property. Preventive drain service is far cheaper than an emergency call and the damage that comes with it.
A failed water heater is never convenient. Hilliard's stocks and installs gas and electric water heaters and can typically handle a replacement quickly — often same-day or next-day depending on availability. We carry both tank and tankless options and can help you choose the right solution for your home's size, usage, and budget.
If your existing water heater is less than 10 years old and experiencing issues — inconsistent temperature, rumbling sounds, discolored water, or a leaking pressure relief valve — it may be repairable. Our technicians will assess the unit honestly and tell you whether repair or replacement makes more sense given the age and condition of the equipment.
Tankless water heaters have become increasingly popular in Pullman's student rental market and among homeowners looking to reduce energy costs. We install and service on-demand systems from major manufacturers and can assess whether your home's gas supply and venting are compatible before you commit to the switch.
Hilliard's has been a go-to trade contractor for builders and general contractors across the Palouse for decades. We provide complete HVAC and plumbing services for new residential construction, commercial buildouts, home additions, and full remodels — handling everything from rough-in to final trim-out.
We work directly with general contractors on project timelines and coordinate inspections to keep your build on schedule. Our experience with local building codes across Whitman County, WA and Latah County, ID means we've already navigated the permitting and inspection process that can slow down contractors unfamiliar with the region.
For homeowners undertaking a major remodel — a kitchen gut, bathroom addition, or basement finish — we offer complete plumbing and HVAC consultation, layout planning, and installation. If you're unsure what's behind the walls or under the slab, we have the tools and experience to assess and plan accordingly before a single pipe is moved.
