Why and When We Should Maintain Furnace and Air Conditioning Systems

903 1000 Dale Ritschard

We all recognize the importance of climate control for ensuring year-round comfort in our homes. However, too often we take our equipment for granted, trusting it to run without failure. Day after day, season after season. Unfortunately, this neglect can lead to unsafe operation, increased running costs, and voiding of warranty protection. Further, it can damage beyond repair some of the most expensive assets in our homes. Therefore, we should be well motivated to understand why, when, and how to maintain furnace and air conditioning systems. We should also know whom to contact!

WHY We Should Maintain Furnace and Air Conditioning Systems

At least three reasons justify a regular look at the heating, ventilation, and air conditioning (HVAC) systems in our homes.

Reason #1: Safe Operation and Durability

Simply put, well maintained equipment outlasts and outperforms neglected equipment. Appropriate care often pays for itself in several ways.

First, it helps avoid the headache of unscheduled, larger expenses in the future — particularly in the heat of summer or the cold of winter. And somehow, these failures just seem more likely to occur when the cost for service is highest: after hours or on weekends!

Next, neglected equipment can lead to secondary damage. For example, it surprises some homeowners to learn that HVAC failure can lead to water damage. Because these systems condense water during normal operation, we must also assure proper drainage. And in some cases, water treatment (especially pH adjustment) must also occur in order to protect pipes. Without inspection and maintenance, leaks and corrosive water can inflict significant damage on your home.

And finally, keeping up with maintenance helps promote health and good indoor air quality (IAQ). Appropriate air filters provide the first line of defense, capturing dust, pollen, and other particulates. By design, these filters sit just upstream of the main air-intake for our equipment. Regardless of type, all such filters foul over time. And as they foul, they can collapse and otherwise create short-circuits that allow particles to pass into our homes. However, beyond filters, neglected equipment can cause other problems leading to exposure to harmful gases (such as carbon monoxide) and non-hygienic sources of air.

Reason #2: Decreased Operating Costs

We have already addressed the impact of neglected filters on indoor air quality. However, we have yet to discuss the effect of fouled air filters on energy costs. Think about it: every pore that a trapped particle closes on a filter decreases the number of available pathways for air. The process is similar to that of a cookie chunk passing into the straw of your favorite blended milkshake. Think about how much more energy it takes to draw liquid up that clogged straw! And in extreme cases, further enjoyment of your drink is impossible until you clear — or replace — the straw. An air-intake becomes starved in a similar manner. This condition leads to increased energy use and eventual failure of expensive equipment.

Reason #3: Protection of Manufacturer Warranty

If you have new equipment, it could prove worthwhile to check your equipment warranty. Many warranties now require homeowners to perform either annual or bi-annual professional maintenance. This provision helps manufacturers ensure that customers do not neglect basic maintenance, such as changing filters regularly. It also helps provide early detection for larger, more costly problems. These failure include major components such as heat exchangers, variable-speed blowers, or compressors. In all cases, the manufacturer can require proof of service prior to warranting its equipment.

WHEN We Should Maintain Furnace and Air Conditioning Systems

We at Emporia Home Services feel that all property owners should consult professionals at least once per year. Further, as indicated above, some manufacturers require inspection bi-annually to keep warranties valid. And finally, in addition to these inspections, filters likely require replacement seasonally, and in some cases even monthly. Bottom line: at least SOMEONE should check on your equipment regularly four or more times per year.

Additionally, we recommend performing a diagnostic inspection prior to moving into a new home or property, whether rented or purchased. Improperly installed or damaged equipment can very likely lead to health and safety hazards as well as operating inefficiencies. Do not accept these dangers nor the cost for corrective repairs. One service visit will protect you, your family, and your investment.

HOW We Should Maintain Furnace and Air Conditioning Systems

Naturally, homeowners can perform much of the seasonal, routine maintenance on their own. As a guideline, we provide a few main pointers:

  • Avoid storage around HVAC systems to ensure safe access and to prevent circulation of harmful chemicals from paints and cleaning products
  • Keep blower motor and air handler free of obstructions, dirt, and debris
  • Inspect furnace compartment for cracks, holes, and corrosion 
  • Watch for water puddles and water marks on or around indoor equipment
  • Rinse your air conditioner coil with water at the start and in the middle of each cooling season
  • Change furnace filters every 60 to 90 days as necessary

However, some owners don’t have the time or feel comfortable working around HVAC equipment. These people should therefore rely upon a licensed, qualified technician to perform all work.

WHO Should Service Furnace and Air Conditioning Equipment

At a minimum, you should insist that any technician show certification by the NATE (North American Technician Excellence) program. NATE represents a recognized standard for training and preparedness in the HVAC community. Additionally, you should ask your technician to spell out what services are included in each visit. In addition to the above list, your equipment should undergo numerous other checks to ensure safe and effective operation. Your NATE technician can accomplish them all — and explain what they mean. The good news: performing these routine check-ups can save an average of 12% on operating costs.

During any tech visit, a customer should remain vigilant to techs who might appear a little too quick to suggest replacing any equipment. Of course, replacement at times does make sense — but you should insist to learn why. And, for the price of a service call, consider seeking a second opinion before making any final decision that could cost you thousands of dollars.

Finally, customers should prepare specific questions for their home and habits in advance of the service call. For instance, you may have questions related to efficiency, home comfort, or IAQ — and may even have attempted modifications on your own. As an example, some owners purchase filters advertised as “allergen blocking” or the like. These filters can restrict airflow, negatively impact performance, or even damage equipment. In this case, one should ask the technician to measure air flow and ensure that equipment and any IAQ solution remain compatible.
