Some signs that your HVAC system may need repair in your Annapolis home include lack of cool air, weak airflow, strange noises, water leakage, and if dust, debris, or unusual odors are coming out even after the filter has been changed. If there is anything that seems out of the ordinary with your system, we strongly advise booking an inspection.

Preparing your HVAC system for changing seasons involves several important steps. Start by replacing or cleaning filters at the beginning of each season, especially during peak times, to enhance airflow and improve efficiency. During the warmer months, check refrigerant fluid levels to ensure that there are no leaks, as fluid can evaporate and condense during the cooling cycle. If you have an outdoor or window unit, be sure to clear debris such as plants, weeds, and tall grass to maintain proper airflow. In the cooler months, adjust your thermostat settings and keep your furnace on a regular heating schedule, and opting to lower the temperature when you’re not home or asleep.Wipe off any dust or debris from your units with a clean cloth. Lastly, be sure to inspect your systems regularly to prevent any long-term issues.

Routine HVAC system maintenance helps slow the aging of your system in your Annapolis home. Consistent inspections and maintenance are also a great way to catch minor issues before they turn into a substantial expense.

We recommend servicing your HVAC system at least twice a year, once in the spring and once in the fall, to ensure your system is ready for the changing of the seasons. CHA has Preferred Service Agreements that will save you money. Your bi-yearly tune-up is included.

We recommend changing your air filter every one to three months. This number can change based on the climate, if you have any pets, and the age of your system.

• Before you start, turn off your HVAC system to prevent it from running while you are changing the filter. You can do this by switching off the thermostat or turning off the power at the breaker box.
• Locate the filter in or near the HVAC unit in your Annapolis home.
• Remove the old filter. Carefully slide out the old filter, paying attention to its orientation. Some filters have an arrow indicating the direction of airflow, which should match the direction indicated on the HVAC unit.
• Using the correct size filter, insert the new filter: Take the new filter out of its packaging. Make sure it is the correct size and type for your HVAC system.
• Insert the new filter into the filter slot, ensuring it is oriented correctly. The arrow on the filter should point in the direction of the airflow, typically toward the blower and away from the return duct.
• Close the access panel or grille.

If your AC is running but not cooling the house, there are several issues that could be at play. One of the most common reasons include a dirty air filter, which restricts airflow. Low refrigerant levels can also be a cause, often due to leaks. Another potential issue is a malfunctioning compressor or blocked condenser unit. Electrical issues or faulty components within the AC system or in the home could also be to blame. Regular maintenance and timely inspections can help identify and resolve these problems, ensuring your home stays cool and comfortable.

Most central air conditioners can last anywhere between 10-20 years. The best way to ensure a long lifespan for your AC is to keep up with regular maintenance and inspections.

Deciding whether to repair or replace your Annapolis home’s HVAC system depends on several factors. The age of the system is crucial: air conditioners and furnaces typically last 10-20 years. If your unit is in the double digits, replacement might be a more cost-effective option. Older units are generally less efficient and more costly to operate than newer ones. More modern units tend to still be under warranty, decreasing repair costs significantly. However, if you find yourself needing frequent repairs for your unit, it may be time to consider a replacement. Financial incentives, like local and federal tax credits for energy-efficient upgrades, can also make replacement a more viable option, even if you have a new system.

• MERV Rating: A measure of a filter’s ability to capture particles, ranging from 1 to 20. 
• Higher MERV: Captures smaller particles and provides better air quality but can restrict airflow.
• Choosing a Filter: Balance the need for air quality with your HVAC system’s capacity to handle airflow resistance.

By understanding MERV ratings, you can choose the right air filter for your Annapolis home’s HVAC system, ensuring optimal air quality and system performance.
