Residential AC Maintenance Services in Hilliard, Ohio & Dublin, Ohio

We don’t mind stopping by to fix your air conditioning. After all, it’s what we do. We would rather service your equipment before it needs emergency repairs.  As part of a seasonal AC maintenance and tune-up program, our HVAC technicians will check refrigerant levels, examine it for leaks, and properly dispose of discharged refrigerant. We’ll also check the controls, electrical terminals, belts, connectors, etc. and then we’ll replace worn, damaged or broken parts before they turn into a major problem.

We’ll also recommend non-emergency replacements and upgrades that can help extend the life of your system. This gives you the information to make a good decision and time to think about what you want to do with your system, before you’re on the spot. There are two types of coils in your AC or heat pump; your indoor evaporator coils and outdoor condenser coils. These coils can become clogged with just about anything over time, depending on where they’re located in your home. This could include dirt, bacteria, pet hair, tobacco smoke, even rust. These things cause erosion, deterioration, and eventual malfunction of AC equipment. Having the equipment cleaned regularly is important. We recommend this at least once a year.  Can’t remember the last time your coils were looked at or cleaned?  Then, it’s probably time for HVAC maintenance.

4 DIY AC Maintenance Projects



Remove any debris or foliage from your outside unit. This involves pulling weeds, plants, yard waste and other debris from the area surrounding your outdoor intake and exhaust vents to make sure nothing can impede airflow. As a general rule of thumb for things in this area, we suggest maintaining at least a three-foot radius.


During the cold months, protect your outdoor AC coils with a cover to prevent ice and other extreme weather from damaging while you aren’t using it. This cover need not cost much, and should not be airtight. A trash can lid or small sheet of plywood secured by bungee cords works ideally.


Open up all vents and registers and check them inside to make sure your air ducts appear clean. Air ducts tend to accumulate dust. If you suspect there’s dirt down inside, use a vacuum cleaner with a HEPA filter if possible, to suck it out. If that doesn’t work, ask us about our comprehensive air duct cleaning service.


Check wire entry points behind your thermostat to make sure there isn’t a gap allowing air through. If you find a gap there, keep in mind this will enable air to get through. You’ll want to apply some caulking to prevent this air from interfering with the thermostat’s ability to provide an accurate reading.

FAQ: AC Maintenance

What maintenance should be done on AC unit?

Regular maintenance of an air conditioning (AC) unit is crucial to ensuring its efficiency, longevity, and optimal performance. Some of the key maintenance tasks that should be performed on an AC unit include:

  1. Cleaning or replacing air filters: Dirty air filters can restrict airflow, reduce efficiency, and cause system failures. It is recommended to check and clean or replace the air filters once a month, or more frequently in areas with high levels of dirt and dust.

  2. Checking refrigerant levels: Refrigerant is the fluid that cools the air inside the AC unit. If the refrigerant level is too low, it can cause the AC to freeze, or it can cause the system to fail altogether. An HVAC professional should be consulted to diagnose refrigerant issues and recharge the system as needed.

  3. Checking and cleaning the condenser coils: The condenser coils are responsible for dissipating heat from the refrigerant, and they can become clogged with dirt and debris over time. Cleaning the coils regularly can improve the efficiency and lifespan of the AC unit.

  4. Checking and tightening electrical connections: Over time, electrical connections can loosen, causing the AC to stop working. Regularly checking and tightening these connections can prevent system failures and ensure the AC continues to operate effectively.

  5. Scheduling annual maintenance: Annual maintenance by an HVAC professional is recommended to ensure the AC unit is in good working order and to identify and address any potential issues before they become more serious.

By performing these maintenance tasks regularly, you can extend the life of your AC unit, improve its performance, and reduce the likelihood of costly repairs down the road.

Is it worth paying for AC maintenance?

Yes, paying for regular air conditioning (AC) maintenance is worth it. Regular maintenance can help to extend the life of your AC unit, improve its efficiency and performance, and reduce the likelihood of costly repairs. With regular maintenance, an HVAC professional can identify and address potential issues before they become serious, saving you money and ensuring your AC operates effectively. In addition, regular maintenance can also improve the indoor air quality, making your home a more comfortable and healthy place to live. Overall, investing in regular AC maintenance is a wise decision that will provide long-term benefits and cost savings.

Is it necessary to clean AC outdoor unit?

Yes, cleaning the outdoor unit of an air conditioning (AC) system is necessary. The outdoor unit contains the condenser coils which are responsible for dissipating heat from the refrigerant. Over time, the condenser coils can become clogged with dirt, debris, and leaves, reducing the efficiency of the AC system. Regular cleaning of the outdoor unit can improve the efficiency and lifespan of the AC, and prevent potential problems such as refrigerant leaks, compressor failures, and system failures. Additionally, a clean outdoor unit can also
