Washington's climate asks a lot of a home's heating and cooling system — cold, damp winters east and west of the mountains, and summers that increasingly bring real heat. Pasco Plumbing provides HVAC installation, repair, and maintenance across the state, applying the same approach we bring to plumbing: honest diagnosis, clear explanations, and a free estimate before any work begins.
Whether it's a furnace that won't hold a consistent temperature, an air conditioning system that's stopped cooling effectively, or a home that's ready for a new heating and cooling system entirely, we walk through what's actually happening with your equipment and what your realistic options are — not a one-size-fits-all recommendation.
On The Job — HVAC ServicesFree Estimate: We'll assess the problem and give you a clear, upfront price before any work begins — every time, no exceptions.
Signs You Need HVAC Services
- Uneven heating or cooling between rooms in the same house
- A system that runs constantly without reaching the set temperature
- Unusual noises — banging, squealing, or rattling — from the furnace or AC unit
- A noticeable spike in energy bills without a change in usage
- Weak airflow from vents throughout the house
- A system that's short-cycling, turning on and off frequently
- Strange odors when the heating or cooling system runs
- A system that's 12-15+ years old and hasn't had recent maintenance
Heating & Cooling Repair
HVAC problems often have several possible causes behind the same symptom — a system blowing warm air instead of cold could be a refrigerant issue, a failing compressor, or something as simple as a dirty filter restricting airflow. We diagnose based on what's actually happening in your specific system rather than assuming the most expensive cause, and explain what we find before recommending a repair.
For furnaces, common issues include ignition problems, a failing blower motor, thermostat miscommunication, or a clogged filter restricting airflow enough to trip a safety switch. For air conditioning and heat pump systems, low refrigerant, a failing capacitor, or a dirty condenser coil are frequent culprits. We carry the diagnostic approach to figure out which one applies to you, rather than replacing parts by trial and error.
New System Installation
When a heating or cooling system has reached the end of its useful life, or a home simply needs a new system installed, sizing matters more than most homeowners realize. A unit that's too large cycles on and off too frequently, wearing out components faster and creating uneven temperatures. A unit that's too small runs constantly and still struggles to keep up. We size new systems based on your home's actual square footage, insulation, and layout rather than defaulting to whatever was there before.
We also talk through efficiency ratings and their real-world impact on your energy bills, since a slightly higher upfront cost on a more efficient system often pays for itself over several years of Washington winters and summers. You'll get a clear, free estimate that reflects the specific system and installation your home needs.
Maintenance That Prevents Bigger Problems
Regular HVAC maintenance — filter changes, coil cleaning, checking refrigerant levels, inspecting electrical connections, and testing system cycling — catches small issues while they're still inexpensive to fix. A system that's properly maintained also tends to run more efficiently, which shows up directly in lower energy bills over a Washington heating or cooling season. We can talk through a maintenance schedule that fits your system and how heavily it's used.
Our Process
Describe The Issue
Tell us what your system is doing — or not doing — and its approximate age.
On-Site Diagnosis
We inspect and test the system's components to identify the actual cause, not just the symptom.
Free Estimate
You get a clear price for the repair, or for a properly sized new system if replacement makes more sense.
Complete The Work
We finish the repair or installation and test full system operation before we consider the job done.
Frequently Asked Questions
We generally recommend a maintenance check once or twice a year — typically before the heating season and before the cooling season — to catch small issues before they become expensive repairs.
It depends on the age of your system, the frequency of past repairs, and the specific issue. Systems well past 12-15 years old with recurring problems are often better replaced than repeatedly repaired, and we'll walk you through the real numbers.
Yes, we handle heating and cooling systems, including furnaces, air conditioners, and heat pumps.
A sudden increase often points to a system working harder than it should — a dirty filter, low refrigerant, or a failing component are common causes worth having checked.
Yes, we provide emergency HVAC service, since a heating failure in winter or a cooling failure during a heat wave can't always wait.
Yes, we install smart and programmable thermostats as part of new system installs or as standalone upgrades to an existing system.
It depends on the specific issue and system type. You'll get a free, clear estimate before any repair work begins.
