A boiler heats water, not air. A circulator pump pushes that water through pipes to baseboard, radiators or tubing under the floor. In Parker, most residential boilers are gas-fired hot water units, many of them high-efficiency condensing models. Lochinvar, Navien, Weil-McLain and Burnham are common brands here.
Radiant floor heat is quiet and even, which is why many custom homes in The Pinery and on larger lots use it. It also means a problem can take a day to notice, because the slab cools slowly.
Most boiler repair work comes down to a short list of parts. Knowing the names helps you follow what the contractor tells you.
The pump moves hot water through the system. When it seizes or its motor fails, the boiler gets hot but the house does not. You may hear a hum with no flow.
Water expands as it heats. The expansion tank gives it room. When the tank fails, pressure swings high and the relief valve starts to drip.
The relief valve opens to protect the boiler from too much pressure. The low water cutoff shuts the burner off when the water level drops. Both are safety parts, and both are jobs for the contractor.
Zone valves open and close to send heat to each area. A stuck valve leaves one zone cold. Ignition parts and flame sensors fail like they do on a furnace. Air trapped in the lines causes gurgling and cold spots.
1.
Set the thermostat for the cold zone to Heat and a few degrees above room temperature.
2.
Check that the boiler power switch is on and the breaker has not tripped.
3.
Read the pressure gauge and write the number down. The contractor will ask for it.
4.
Write down any error code on the boiler display.
5.
Outside, make sure snow or ice is not blocking the boiler vent and intake pipes.
Stop there. Do not open the relief valve, add water, bleed radiators on a pressurized system or reset the boiler over and over. Those steps are for the contractor.
Still no heat after these checks: (303) 647‑3227A boiler that is down on a night in the teens is urgent. Pipes in outside walls and in the boiler loop itself can freeze. You can call any time, including nights, weekends and holidays. The contractor will tell you when they can come out. See emergency HVAC repair for more.
Safety first
If you smell gas or your carbon monoxide alarm goes off, leave the house first. From outside, call Xcel Energy's gas emergency line or 911. Call us only after everyone is safe.
Boilers are less common than furnaces in Parker, so it matters that the contractor works on hydronic systems often. Many boilers here sit in basements next to the water heater, and some newer combi boilers do both jobs. Hard water and long winter run times wear on pumps and valves.
If you also have forced air heat, furnace repair covers that side. For a whole-house outage, see no heat, and for the bigger picture, heating repair.
1.
You call (303) 647-3227 and say what the boiler is doing.

Your call goes to an independent local HVAC contractor who works on boilers.
3.
They ask about the brand, the pressure reading and any error code.
4.
If a visit makes sense, you set the time with them directly.
Have the brand and model ready. It is on a label on the boiler. HVAC Parker CO does not do the work or set prices. The contractor handles the visit, the diagnosis and the bill.
Talk to a boiler contractor: (303) 647‑3227Common causes are a failed igniter or flame sensor, low water pressure that trips the low water cutoff, or a blocked vent. Write down any error code and the pressure reading, then call.
A dripping relief valve usually means the pressure is too high, often from a failed expansion tank. It can also mean the valve itself is worn. Do not cap or plug it. Call and have it checked.
A stuck zone valve, a failed circulator on that zone or air in the lines are the usual reasons. The contractor can tell which one from a few questions.
Boilers often last longer than furnaces. If the heat exchanger is sound and the repair is a pump or valve, repair usually makes sense. If it leaks from the heat exchanger, ask the contractor to compare repair and replacement.
Radiant and hot water heat works quietly until it stops. Call (303) 647-3227 and you will be connected with an independent contractor who works on boilers in Parker.
