HVAC Repair in Dublin, CA
Troubleshooting and repair for furnaces that blow cold air, fail to ignite, short cycle, or heat unevenly.
Alamo winters are mild compared to much of the country, but cool, damp nights and chilly mornings still make a working heater essential from late fall into spring. When your furnace or heating system falters, we can come out from Dublin to track down the problem and restore steady warmth.
Heating systems often sit idle for months, so the first cold snap is when many problems show up. Watch for:
If you ever smell gas, leave the house and contact your gas utility right away before calling for repair.
Every heating call follows a clear process so you know what to expect:
Because local heaters run less often than in colder regions, small issues can go unnoticed for years. A flame sensor may slowly gather residue, or a blower may collect dust, and the problem only surfaces when temperatures drop. Many Alamo houses date from the 1970s through the 2000s and use gas furnaces installed in garages, attics, or hall closets. Attic installations in particular deal with temperature swings and dust that can wear on components.
Damp winter air can also affect venting and condensate drainage on higher-efficiency furnaces. We check these areas during repair visits so moisture does not cause a repeat breakdown.
Sometimes a repair reveals that another part of the system needs attention. ReliableFix also handles HVAC Maintenance before the heating season, Heat Pump Service for homes that use electric heating, Thermostat Repair when controls send the wrong signals, and Furnace Installation when an older unit is no longer worth repairing.
Dust settles on the heat exchanger and burners over the warm months. A light burning smell for a short time is normal, but if it persists or smells electrical, have the system checked.
Not usually. Short cycling can point to a dirty filter, a faulty flame sensor, an overheating issue, or a thermostat problem. It is worth having it diagnosed.
Confirm the thermostat is set to heat, replace the filter if it looks dirty, and make sure the furnace switch and breaker are on. If heat still does not come on, give us a call at (669) 259-1198.
