HVAC Repair in Dublin, CA
Troubleshooting and repair for furnaces and heating systems that blow cold air, short cycle or fail to start.
Winter in Hayward rarely brings snow, but chilly nights and steady rain can leave a house feeling cold and clammy for months. Heater trouble tends to show up on the first truly cold evening of the season, right after months of sitting unused.
ReliableFix repairs forced air furnaces, wall heaters and other common heating setups for homeowners throughout Hayward, working from our base in Dublin. Our goal is simple: figure out what changed, fix it properly, and explain what we did.
Heating systems usually give hints before they quit completely. Pay attention if you notice any of the following:
If you ever smell gas, leave the home and contact your gas utility right away before calling for repair.
The technician starts at the thermostat to confirm it is calling for heat. Next, we open the furnace and inspect the ignition system, flame sensor, burners and safety switches. Airflow matters as much as the flame, so we also look at the filter, blower motor and return vents. We check the venting and watch the system run through a full cycle to see where it falls short.
Before we do any work, you get a clear explanation of the problem and your repair options.
Many single-family houses and townhomes in Hayward were built from the 1970s through the 2000s. Furnaces in these homes are often found in garages, attics or hallway closets. Attic units can be hard to reach, and their ducts may have lost insulation over time. Closet furnaces sometimes struggle to pull in enough return air when the doors stay shut. Damp winters can also encourage rust on older parts and vent connections. Knowing where and how your system is installed helps us narrow down problems faster.
After a repair, a few related services can make next winter easier. Seasonal HVAC maintenance cleans and inspects the furnace before you need it. If your system is near the end of its useful life, we can talk through furnace installation. Thermostat repair resolves many heating complaints that start with faulty controls. For homes that heat with an electric heat pump instead of gas, our heat pump service covers that equipment.
A faint burning smell for a short time is often dust burning off the heat exchanger after a long break. If the smell lasts or seems electrical, shut the system off and have it inspected.
Common causes include a dirty flame sensor, a failing igniter or a problem with gas reaching the burners. Each of these needs hands-on testing to confirm.
Many households check the filter monthly and replace it every one to three months. The right schedule depends on the filter type, pets and how much the system runs.
