Replace or Clean Air Filters

The air filters in your HVAC system are an important part of maintaining indoor air quality because they trap dust, pollen and other pollutants and keep them from circulating throughout your home. However, when they get dirty and clogged, they restrict airflow and force the system to work harder, reducing its efficiency, shortening its lifespan, and increasing energy consumption. That leads to higher bills. Replace disposable filters or clean reusable ones every 1โ€“3 months, or more often in dusty environments. This simple task ensures optimal airflow and keeps your homeโ€™s air fresh and clean.

Clean the Indoor Unit

The part of your HVAC system that sits inside your house contains key components that need regular maintenance to keep the system running properly and efficiently. First, to be safe, shut off the power to the unit by flipping the system breaker switch to the off position. Then, remove the access panel and clean the evaporator coils with a foaming coil cleaner, and flush the drain pan and drain pipe with a bleach-water solution to prevent clogs and mold growth.

Inspect and Clean the Outdoor Unit

This is an important part of HVAC summer maintenance. The outdoor unit is prone to accumulating leaves, grass, trash and twigs, which block the free flow of air through the vents, decreasing efficiency and making the whole system work harder. Remove the grill and clean out debris both inside and outside the unit, and use a garden hose and coil cleaner to remove stubborn dirt and grime from the condenser coils. Make sure landscaping plants are trimmed back at least two feet away from the unit.

Straighten the Condenser Fins

The fins on the condenser are there to maximize the surface area to help dissipate heat more effectively and make the cooling process faster and more efficient.ย  Theyโ€™re thin and fragile, bending easily, so youโ€™ll usually find at least a few impacted areas. Bent fins obstruct airflow and reduce the ability of the coil to transfer heat, lowering efficiency and raising your utility bill. Use a fin comb, which you can buy at your local hardware store, to very carefully straighten bent fins.

Program Your Thermostat for Efficiency

A programmable or smart thermostat can help in reducing energy consumption by allowing you to regulate temperatures for different times of the day. For example, you can set it to automatically lower temps during the day when no oneโ€™s home, and raise them just before you return. Avoid drastic temperature changes that can put a strain on the system.

Check Coolant Lines and Ductwork

Check your refrigerant lines for missing or damaged insulation, and repair or replace as needed. Keep an eye out for any areas where leaks might develop. Also, inspect your ductwork for leaks and blockages. Loose seams and tears can be repaired with mastic sealant or professional-grade duct tape. Itโ€™s a good idea to consider professional maintenance in these areas as they will have a better eye for problems, and accessing ductwork is dirty and physically demanding work.

Test the System Before Peak Summer Heat

Once youโ€™ve finished with your HVAC summer maintenance, youโ€™ll want to put your system through its paces to make sure everything is working properly before the hot weather arrives. Turn the AC on and run it on high until youโ€™re satisfied with its operation, listening for any unusual noises or other signs of a problem. This is good practice for the change of the seasons because youโ€™ll basically go through the same routine when preparing your HVAC for winter.

Consider Professional Maintenance

While these maintenance tasks are adequate for preparing your HVAC for summer, itโ€™s a good idea to have a pro conduct an inspection at least once a year (and to handle any maintenance you donโ€™t feel comfortable with as a DIY project). Theyโ€™ll do a more in-depth examination, checking refrigerant levels, cleaning hard-to-reach components as well as filters, coils and ducts, and optimizing system performance. A trained, licensed technician will be able to identify issues before they turn into major problems requiring costly repairs or replacement.

Your HVAC system warranty may also require professional maintenance for any claims to be valid. Consider scheduling a professional inspection before seasonal high-demand periods.

10 Common HVAC Problems and How To Prevent HVAC Repair

You rely on your HVAC system to keep your home comfortable all year long. Your heating and cooling system spends many hours in operation day in and day out, year after year. Even though these systems are built to handle a lot, the reality is, you’ll probably run into a problem eventually.

So, what are the most common culprits for HVAC malfunctions? We’ll break down the top 10 most common reasons for HVAC system problems and show you how proactive maintenance and smart habits can cut down on costly repairs.

It should also be noted that most of these issues can be avoided by having regular HVAC maintenance performed on your system by a professional, saving you money in the long run. Spot these 10 common HVAC problems and troubleshoot like a pro:

  1. Unit Not Turning On

    Causes:

    • Dead thermostat batteries
    • Tripped circuit breaker
    • Wiring issues

    How To Avoid It

    If your thermostat uses batteries instead of being hardwired into your home electrical system, check them regularly, as low power can affect proper operation. Also inspect your circuit breakers periodically to make sure theyโ€™re not tripped. If you suspect faulty wiring is the culprit, call a professional immediately for an inspection and repair.

  2. Poor Airflow

    Causes:

    • Dirty air filters
    • Clogged vents
    • Blocked ducts

    How To Avoid It

    This is the most common HVAC problem. Replace your air filters every 1-3 months to prevent airflow restriction, or more frequently in a dusty environment. Also, remove obstructions like grass, shrubs and limbs from around outdoor units and vents. Consider having your ducts cleaned to remove accumulated dust and debris.

  3. Uneven Temperature Distribution

    Causes:

    • Poor insulation
    • Blocked vents
    • Lack of zoning control

    How To Avoid It

    Reinforce your homeโ€™s insulation where needed, especially around leak-prone areas like windows and doors, and consider installing dampers in your ductwork to allow you to regulate airflow into living spaces more precisely. For larger homes, think about installing a zoned HVAC system for a better temperature control in each room.

  4. Strange Noises (Whining, Squealing or Rattling)

    Causes:

    • Loose components
    • Worn-out fan belts
    • Airflow obstructions

    How To Avoid It

    Of all HVAC maintenance issues, this is among the easiest to address. Keep moving parts well lubricated as per the instructions in your ownerโ€™s manual. Tighten any loose screws or bolts during routine inspections and replace fan belts that look worn or are squealing. Clean or replace air filters regularly to avoid strain on components that could cause noise issues.
