This is usually an issue with older furnaces with a rusted heat exchanger, and the rust and other dust are burning off for the first few minutes. If the smell persists, you should call us to assess the problem further.

Dirty systems (dusty & old ducts) can also have a persistent musty smell when in heat mode.  Duct cleaning may be an option if properly performed.

• Ensure nothing obstructs the furnace’s minimum clearances (refer to your installation/owner’s manual). Nothing should touch the venting system (fire safety) and restrict combustion air to the furnace intake louvers. Avoid using your furnace equipment closet or garage platform as a storage area.  It poses a safety concern and makes it difficult to access the equipment in the case of an emergency.
• Air filter maintenance – Ensure that the furnace filter is replaced per the manufacturer’s requirements. That means that your typical 1” filters need to be replaced every 3 months and your thicker IAQ filters between 3 months and a year. You can call our Front Desk for more information on your specific filter.

Note that ALL Haven Installations include a hospital-grade MERV16 Air Filtration System that requires an annual filter replacement.

• Inspect the furnace periodically after it rains and ensure no water leaks into the furnace from the venting system (flue).
• Pay attention to any abnormal sounds during the furnace’s operation. Turn the unit off if it does not sound right to you!
• If your system is installed in the attic, ensure no water is in the secondary protection pan.

Call us at (714) 332 – 6302 for more comprehensive maintenance service and any additional questions we can answer for you. Note that your furnace manufacturer requires annual furnace maintenance.

• The thermostat is set for heat, but nothing happens. If the thermostat is battery-powered, make sure the batteries are still good. Verify that there is power to the furnace. Confirm that the furnace door is fastened properly.

Call us for service if the above does not resolve the problem.

• The furnace clicks, but the burners will not come on.  There is a problem with the ignition system. Turn the appliance off and call us for service.
• The burners come on for a while, but the blower motor does not. This indicates that either the blower motor, the main control board blower relay or safety has failed/opened. Turn the appliance off and call us for service.

A malfunctioning heating system can be a real nuisance to deal with during the winter season. If your heating system is showing signs of wear and tear, it’s important to recognize them and take action quickly. Some common signs that your heating system needs repairing include strange noises coming from the furnace, a decrease in heat output or effectiveness, an unexpected increase in energy bills, or a yellow pilot light (instead of the normal blue one).

The time it takes for a heating repair service to fix a system depends on the severity of the issue, type of repairs needed, the complexity of the system, and availability of parts. Slight issues can sometimes be fixed in a matter of hours, while more extensive repairs may take several days. Ask your HVAC company for an estimated timeline before they begin so you know how long the repair process will take. A reliable heating repair service should be able to provide this estimate.

Regular maintenance for your heating system is essential for safe and efficient operation. We recommend scheduling a professional inspection and tune-up at least once a year, before the heating season starts. This helps keep the system running smoothly and safely, as well as identifying any potential problems before they become more serious. Professional maintenance also helps to improve energy efficiency and extend the life of the system, saving you money in the long run.

A typical heating maintenance service should include a thorough inspection of your system, cleaning interior components, checking for loose electrical connections or worn parts, and running a diagnostic test to detect any issues. The technician may also check the flue pipe, air filter and thermostat, flush and refill fluids, lubricate moving parts, and make any necessary adjustments. Additionally, they may offer some recommendations on how to improve your heating system’s performance or conserve energy.

There are a couple of scenarios that could lead to water leaks from a furnace:

• If the water leak appears after a rain, then there is most likely a leak in the furnace venting system on the roof.
• Condensing (high efficiency) furnaces may have leaky hoses or clogged drain parts that need to be repaired or cleaned.
• Poor maintenance

Call us for more information on how to resolve your specific problem.

First confirm that the thermostat is set to OFF. If the furnace is still producing heat or the blower motor keeps running, you will need to call for service, so we can identify the specific problem.

To turn the furnace off, unplug it or turn the specific breaker off until the appliance can be serviced.

Call us for more information on how to resolve your specific problem.

If the thermostat uses batteries, replace them or make sure that the existing batteries are still in good working order. 

If you have recently replaced a filter inside the furnace, make sure that the furnace door was reinstalled properly. 

Call us for more information if the above instructions do not resolve the issue.

Make sure that your filter is clean.

If you have access to your attic, you can check to see if any ducts are disconnected.

Make sure that none of the vents are blocked (intake & returns)

Call us for more information if the above instructions do not resolve the issue.

When a furnace blows cold air (in heat mode), it indicates that a safety or ignition sequence failed several times in a row and the furnace locked itself out for safety reasons.

The furnace will try to fire periodically after a predetermined interval of time has elapsed and if the fault has corrected itself, the furnace will operate.

This problem will require service to resolve. Call us to set up a service appointment!

First, turn the system off, use a shop vac with a brush attachment to gently brush the grill.

In more humid environments, a damp cloth with a drop of dish soap may be required to remove all of the accumulated dust.

Note that an excessive amount of dust build up over a short period of time, may indicate indoor air quality issues that should be assessed.

Call us for more information if the above instructions do not resolve the issue.

Make sure that all the registers are open and that none of them are blocked.

Try NOT to close more than 10% of your overall vents to prevent the system from overheating.

This problem is usually related to poor air balance within the air duct system. 

Two story homes without zoning systems can also exhibit this problem. 

We have specific tips & tricks for these applications, so call us for more information!

We can’t be sure what causes the noise, so it would be wise to ask for an expert to have a look. Turn your appliance off and call us to set up a service appointment.

This can indicate one of several furnace problems, but is often related to a main control board or relay failure. The equipment will require service.

This can indicate that there is insufficient airflow and the furnace is protecting itself from overheating by shutting itself off to cool down.

• Check & replace the filter. 
• Make sure all vents are open. 
• Make sure all the grills are unobstructed.

Call us for more information if the above instructions do not resolve the issue.

Most modern furnaces (less than 35 years old) will not require you to light a pilot flame. If your furnace is older and does require a standing pilot you can do the following: 

Follow the detailed instructions provided with your appliance (typically found on the furnace door or in the burner compartment).

If you do not have instructions, you can call us for service and we will complete a tutorial with you while we are on site.

You can call the gas company. They will usually come for free and start up your appliance.

All central heating/cooling systems need to have a filter installed. Here are some of the locations they can be found:

Older furnaces

• Inside the blower compartment of the furnace
• Filter housing underneath furnace
• Attic/basement/subfloor systems

Central air filtration system – The filter housing is often located next to the furnace on the intake side.

1” filters – The filters are usually in a ceiling air intake grill (check for large grills in the ceiling).

New system

If it is a new home and you can not find the filter, it is advisable to call us for maintenance so we can assess where the filters are located and how many they are. We will provide you with the system maintenance requirements as part of our service.
