Owyhee Heating, Air Conditioning & Plumbing has served the greater Nampa area since 1946, and our downtown office at 1020 1st St S, Nampa, Idaho 83651 still dispatches. We repair, maintain, and replace furnaces, heat pumps, air conditioners, water heaters, and drain lines for homes in all three Nampa ZIP codes (83651, 83686, and 83687), plus nearby Caldwell, Meridian, and Kuna.
Nampa homes range from older houses near downtown to subdivisions built in the last few years off Garrity Boulevard and around Lake Lowell. Those homes need different things. An older house may need a drain line cleared or a furnace replaced after decades of service, while a newer one may need its first water heater replacement or an AC that was undersized by the builder. Our licensed team handles both, and our phones are answered live 24 hours a day, 7 days a week.
Furnace and Heat Pump Service for Nampa Winters
Canyon County sits in IECC climate zone 5B, a dry climate with long heating seasons and regular freezing nights from late fall through February. Many Nampa homes heat with natural gas from Intermountain Gas, and a growing number use electric heat pumps on Idaho Power service. Our heating services cover both, along with geothermal systems, baseboard heaters, electric furnaces, and propane heaters.
If your furnace short-cycles, blows cool air, or makes new noises, a technician can diagnose the cause and give you a price before any repair starts. When a system is near the end of its life, we walk you through furnace installation and replacement options sized for your home. A yearly furnace tune-up in the fall is the simplest way to catch worn parts before the first cold snap. Homeowners comparing systems can also look at heat pump repair and installation, which provides heating and cooling from one unit.
When Your Air Conditioner Can’t Keep Up With Canyon County Summers
July and August afternoons in the Treasure Valley regularly reach the 90s, and the dry heat keeps an air conditioner running for hours at a time. Warm air from the vents, ice on the refrigerant lines, or a unit that runs without stopping are signs it needs attention. Our AC repair team works on all major brands, from central air systems to ductless mini splits in additions and converted garages.
A spring air conditioning tune-up clears debris from the outdoor unit and checks electrical components and airflow before peak season. Dusty coils are common in neighborhoods near open fields and construction, and our coil cleaning and repair services help restore cooling capacity. If repair costs start to approach the value of an aging system, we can quote a full replacement so you can compare.
Plumbing and Drain Problems in Older and Newer Nampa Homes
Nampa nearly doubled in population between 2000 and 2019, so many neighborhoods have homes of very different ages on the same street. Older homes near downtown tend to need drain cleaning and sewer cleaning for aging lines and root intrusion. Newer homes often reach water heater replacement age around the same time, and our water heater services cover repair, flushing, and replacement.
The City of Nampa reports water hardness of up to about 7 grains per gallon, which is enough to leave scale on fixtures and inside water heaters over time. Our water softening and filtration installs reduce that buildup. For everything else, from leaking faucets to running toilets, our plumbing services are handled by Idaho-licensed plumbers.
Repair or Replace? How Nampa Homeowners Decide
The right answer depends on the age of the equipment, how often it has needed repairs, and how well it heats or cools your home today. A furnace or air conditioner that is 15 years or older, needs a major part, and has struggled to keep rooms even is often a better candidate for replacement than another repair. A younger system with a single failed component usually is not.
Your technician prices both options so you can compare them side by side. If you lean toward a new system, we size it to your home instead of matching the old unit, which matters in Nampa houses that have added rooms, finished basements, or new windows since the original equipment went in. Water heaters follow the same logic: a leaking tank needs replacement, while a unit with a failed element or thermostat can often be repaired.
What to Expect During Your Service Visit
You can call or book online, and we’ll schedule a time that works for you. Your technician diagnoses the problem, explains what’s wrong, and gives you upfront pricing options before any work begins. Every job is backed by our 100% satisfaction guarantee, and qualified homeowners can spread the cost of a new system with flexible financing.
