HVAC: Furnace Filters

Furnace Filters: The Ultimate HVAC Equipment Defender.

Homeowners often believe that the furnace filter’s primary job is to clean the air in your home. Your furnace filters will help aid in improving air quality, by remove particulates and contaminants from the recirculated air, but their main purpose is to protect blowers and other internal components from damaging build-up.

Furnace FiltersFilters keep your HVAC system clean and efficient by removing dust, dirt, hair, and other particles from being pulled into the blower from the return air ducts. This makes them the ultimate HVAC equipment defender.

One way to prevent your heating system from becoming bogged down is by scheduling regular filter checks. Pay attention to the filters you are buying and understand the recommended duration of use for the filters you choose. Buying the correct size for your furnace ensures that you are maximizing filtration in your heating system.


KNOW YOUR FILTER: The two most common variations of furnace filters are pleated filters and semi-permanent reusable/washable filters. Knowing which filter is in your furnace is the first step. Pleated disposable filters are the most common, with various sizes and types available at local stores like Fred Meyers, Target, Home Depot, Etc.

CORRECTLY INSTALLED: Dirty filters and incorrectly installed filters have a lot in common. They can both add more resistance to airflow, which makes the system work harder, become less efficient and more expensive to operate. Make sure your filters are correctly installed. The chamber that houses your filter is between the return air and a supply air sections of your furnace, and there is usually a panel where filters can be easily accessed.

CHECK FOR EXCESSIVE DEBRIS & REPLACING WHEN NEEDED: In between replacing your filters, we suggest regular filter checkups. Pulling out your filters regularly, to see how dirty they are, can help you get an idea of how often they need to be changed. While checking the filters you can remove any chunks of debris, hair or dust balls that you may find loose in the compartment and/or on the filters.

You will want to replace your filters primarily based on how quickly they get dirty or at least based on what the packaging recommends; 30 days, 90 days, etc. You may find they get dirty faster during the colder months, requiring more frequent changing or cleaning, due to the furnace being used more. Older homes and homes with pets generally require the filters to be changed or cleaned more frequently.

When changed and maintained regularly, filters can extend the life of your heating system. They can also help keep maintenance costs down. The primary purpose of a furnace filter is to protect HVAC equipment, with the added benefit of improving indoor air quality. Regular duct cleaning also plays an important role in furnace lifespan and home air quality.

Baseboard Heaters

Winter Start-Up Inspection: Hot Water [Boilers] Baseboard Heaters

Even, steady and smooth heat distribution is one thing that people love about this heating option. Baseboard Heaters [boilers] are often viewed as a low-maintenance heating option making them a popular choice, and with advancements in boilers and baseboard systems, these heating systems are becoming just as efficient as forced air systems. However, there is still a level of maintenance that is required to ensure you are maximizing your heating system’s efficiency. Our Winter Start-Up Inspection special can help give you peace of mind.

Baseboard Heaters

What are the common reasons that baseboard heaters [boilers] break or stop working?

#1: Pumps, controls or thermostat components stop working

#2: Low water pressure caused by air in the pipes impacting radiating heat

#3: Frozen pipes due to cold drafts, freezing temperatures, and inefficient systems

A Hot Water or Baseboard Heaters require a boiler to heat the water that is then dispensed into tubing that resides in the baseboard units or flooring of your house. This heating system relies on various valves to let water in and out of the system. During our inspection, a certified HVAC Specialist will check your heating system to make sure that it is operating at its best.

The following are some of the items that will be inspected:

Pressure gauge


Valves, including relief valve

Check for leaks or standing water

Circulating pump & motor

Gas supply, burners, and control valve

Inspect Boiler

Pilot Light/Electronic Ignition

Vent Connection

Draft Hood


Our HVAC Specialist will make notes of any possible concerns with your heating system, that they may uncover during the inspection. This preventative measure may help to identify issues before they require costly repairs or even replacements.

For example, it is often advised to get your heating system purged. Purging your heating system allows the boiler and pipes to be flushed clean of air, which can help prevent lockouts and other heating system failures. It is advised you consider getting your heating system purged by an expert once every three to five years, or as recommended.

3 Benefits of a Professional Duct Cleaning

Duct Cleaning: Should I Have Mine Done? Over time, it is natural for ducts, fans, and registers to accumulate dirt, dust, pollen, and particles. If moisture becomes present, there is potential for musty odors or mold to grow. Many people call asking questions about the process of duct cleaning; when to get ducts cleaned, allergies associated with air ducts, and associated costs.

Duct cleaning is done to remove dust, debris, and allergens from various heating and cooling system components of a forced-air system.  During our cleaning process, A Mountain Mechanical Tech, will scrub and vacuum out your ducts using a high-powered suctioning system. Supply and return air ducts and registers, grilles, diffusers, heat exchangers, heating and cooling coils, drip pans, fan motor, fan housing, and the air handling unit housing are all cleaned during this process.

It is highly advised to also have your dryer vents purged to remove lint build-up and dust from your drying system.

Benefits of Duct Cleaning

  • Preventative Maintenance – A clean system will run smoother and more efficiently making your furnace work less while extending the life of your system. In a case where furnace filters are not being changed regularly, a cleaning may be even more pertinent for preventative maintenance.
  • SafetyFire Risk: A clean system, including dryer duct cleaning, helps to minimize potential fire hazards and risks. Dust and lint catch fire easily and can increase the speed of which fire spreads through your house.
  • Health – Air Pollution: A clean system helps minimize air pollution, dust, and pollen, that is pushed into your home environment. Dirty ducts may be a cause of indoor allergies or have other effects on your health.

We suggest you consider getting a duct cleaning every 5 to 10 years.

The cost and time associated with a duct cleaning are hinged on the square footage of your home and the number of registers you have. The level of contamination, access to the heating system, and the request for dryer vent cleaning may also change the quote.
