Air Conditioner Maintenance - Homeowner Tips

AC Repair & Service

Clean the outside unit(s) – Keeping an outdoor AC unit is important for maintaining its efficiency. Dirt, debris, and obstruction reduce air flow and increase wear and tear of the unit(s). Regular cleaning prevents clogged condenser coils, blocked air vents, and damage to the fins while maximizing efficiency and lowering energy bills.

 Regularly replace air filters – Air filters trap dust, dirt, pollen, and other airborne particles in your home. Clogged air filters reduce efficiency of your unit(s) causing the unit to work harder and increasing the chance of a system break-down. Changing your air filter is a simple yet important step in maintaining the health of your AC unit(s).

Q: How can AC preventative maintenance help me save money on repairs and energy bills?

A: AC preventative maintenance helps you save money on repairs and energy bills by identifying potential issues before they become significant problems. Maintenance also keeps your HVAC unit running efficiently which reduces the unit’s energy consumption and energy costs while increasing the unit(s) lifespan.

Q: Can I perform AC preventative maintenance on my own, or do I need to hire a professional?

A: Some basic air conditioning maintenance tasks, such as changing air filters, can be done by homeowners. However, it’s recommended to hire a professional for AC preventative maintenance as they have the knowledge and tools needed to professionally inspect and tune up your air conditioner(s). The AC technicians at Lantz’s Lakeside Plumbing & AC perform a thorough inspection and provide trusted AC maintenance services when you need it.

Q: What are some common signs that my AC unit needs preventative maintenance or repairs?

A: Common indicators of an air conditioning unit needing preventative maintenance include decreased airflow, strange noises or smells, uneven cooling, and higher energy bills.

Q: How can I prepare my AC unit for the summer season to prevent breakdowns?

A: The best way to prepare your HVAC system for the summer season ahead and prevent breakdowns is by scheduling preventative maintenance with a professional HVAC service company. Our technicians clean the outside unit, change air filters, ensure proper insulation and sealing, and adjust thermostat settings to ensure your system(s) is running at its peak performance.

Charlie and crew replaced our A/C unit. They were courteous, professional and knowledgeable regarding the work. They explained what had to be done and completed the job in a timely manner. Would definitely recommend this crew of professionals!

Ed and Charlie were quick to respond when our AC went down this past week at our vacation rental. Our AC unit was 16 years old and we knew it's life was coming to an end. We had a rental coming in on the weekend and it was Tuesday. Ed jumped into action and we received quotes on several options and they installed it on Thursday! Thank you team Lantz!
