Santa Rosa HVAC Contractor Shares 10 Furnace Repair Questions and Answers
Santa Rosa HVAC contractors have customers with certain furnace repair questions that commonly come up time and again. I have decided to answer some of your questions here on this blog so that those of you who learn about furnaces through the internet can find answers.
Since your furnace creates and maintains the bubble of heating comfort that keeps you, your family and your home in warmth, of course you have questions. Here are some common furnace questions.
1. What is an HVAC System?
HVAC stands for heating, ventilating, and air conditioning. It’s an umbrella term that covers all of your home heating, cooling, and temperature systems. For that reason we are called your Santa Rosa HVAC contractors.
2. What Does a Furnace Do?
For homes, a furnace, or boiler, serves to heat up air and/or water. This is how you get the warm air when you turn up the thermostat. It’s how you get hot water when you turn on the tap. When the furnace isn’t properly heating air or water, then you have furnace issue.
3. How Does a Furnace Work with Central Heating?
The furnace acts as the central point of heat generation. Heat is created in the furnace and then goes through your ducts to come out of the vents.
4. Are Stand-Alone Electric Heaters a Good Substitute?
Electric heaters are not a substitute, but can serve to take some of the stress off your furnace or central heat. These appliances come in all shapes, sizes, and capacities. It’s perfectly okay to use one or more so that you can turn down your thermostat and put less strain on your HVAC system.
5. What are the Most Common Gas Furnace Problems a Santa Rosa HVAC Contractor is asked?
Like any piece of mechanical equipment, a gas furnace can have trouble from time to time. An Santa Rosa HVAC contractor is called in because of:
- Frequent stops and starts
- A lack of heat or poor heating
- No pilot light
- Noises, such as rattling, squeaks, or clicking
6. What is the EPRL Error?
An EPRL error is one of many that can show up on a furnace’s control board. It’s a flame sensor fault. It usually only means the flame sensor and flame rod need cleaning.
The EPRL and other lights can come on for different reasons as well.
- Electrical issues with the control card
- A faulty control board
- A failing ignition system
Because of these other possibilities, always inform a qualified Santa Rosa HVAC contractor about control board errors.
7. What Causes Clicking Noises in a Forced-Air System?
The most common reason for the clicking noise is the filters. Remember to change your filters regularly. If the noise doesn’t stop after you install a new filter, call your Santa Rosa HVAC contractor. A side note: Changing filters can eliminate other possible issues as well.
8. What Causes Clicking Noises in a Gas Heater?
Much like the EPRL error, a clicking noise from your gas heater may have to do with the flame sensor or faulty ignition.
9. What Do You Do When the Fan Isn’t Coming On, the Diagnostic Light Dies, and the Unit is Making a Humming Noise?
Check fuses on the circuit board. If one is blown, you can replace it with the same rated fuse. After that, you can restart the system. When looking for the circuit board, make sure to check the manufacturer’s guidelines. If the problem persists, it may indicate another problem. Call a Santa Rosa HVAC contractor before you make a costly mistake.
10. What Do You Do if You’re Getting Little or No Air Through the Ducts?
You have either dirty air filters or blocked intakes. This is one reason you should replace your filters regularly. You must also make sure that you do not have any vents that are blocked. This is one reason we suggest that you do not totally seal your vents, even in rooms that you don’t commonly use. This can cause trouble for your system.
Of course, it’s impossible for me to address every possible issue here. A problem may seem to have a simple solution when really it’s indicative of a difficult issue. If in doubt, please call us at Affordable Heating and Air 707-953-3345.
