  • Increased energy efficiency: Regular maintenance helps ensure your AC system operates at its best. Over time, dust, dirt, and debris can accumulate on the components, such as the evaporator coils and air filters. This restricts airflow and forces the system to work harder to cool your space, leading to increased energy consumption and higher utility bills.
  • Cost savings: Routine maintenance helps reduce utility bills and prevent expensive repairs or premature replacement of the system. It also prevents major breakdowns and improves efficiency.
  • Extended life span: Proper maintenance can significantly extend the life span of your AC and help prevent breakdowns. Regular inspections and system checks allow us to identify and address minor issues before they get worse.
  • Improved air quality: Dust, pollen, mold spores, and other contaminants can accumulate in the system and get circulated throughout your space, leading to respiratory problems and allergies. During system maintenance, air filters can be cleaned or replaced, and the system is thoroughly inspected for any signs of mold or microbial growth.
  • Enhanced performance: Our qualified and certified technicians will check and calibrate the system’s controls, clean the condenser coils, lubricate moving parts, and inspect all other components for proper operation.
  • Warranty compliance: Many AC manufacturers require regular maintenance as a condition for warranty coverage. Neglecting maintenance can void your warranty, leaving you responsible for any repair or replacement costs.

Homeowner Tips for AC Maintenance: Changing Your Air Filters

Dirty air filters put a strain on your air conditioner system so proper air filter maintenance is crucial to keeping your AC system running properly. One of the most common causes of early breakdowns of AC systems is a clogged filter, which restricts airflow. A dirty air filter can also cause poor indoor air quality due to accumulation of allergens and pollutants which can lead to illness and health problems.

Changing or cleaning your air filter every 90 days is highly recommended. If you have pets or live with immunocompromised family members such as infants or elderly individuals, you may need to replace your air filter more frequently such as every 45 days to avoid triggering allergy and asthma symptoms. Air filter maintenance is one of the easiest and most effective things you can do to keep your air conditioner running properly between service appointments.

Common AC Tune-Up FAQs

How often should I schedule AC maintenance?

On average, your AC should be serviced at least once a year, usually during the spring. This way you can ensure it’s ready when the warm weather sets in. We recommend system checks twice a year to ensure your HVAC system is working properly year-round.

Is a professional AC system check worth it?

Having a certified HVAC technician look over your AC can save you time and money when it comes to repairs. Our team can provide professional maintenance that prevents costly AC repairs in the future.

How often should I change my AC air filter?

On average, air filters should be changed every 90 days. But if you have allergies or are more sensitive to dust and pollen, changing your air filter every 45 days is recommended.

If I replace my outdoor unit, do I need to also replace my indoor unit?

In most cases, yes! Air conditioners and heat pump outdoor units are manufactured to match with the indoor unit. Replacing one without the other can cause a strain on your cooling unit and result in reduced performance and/or efficiency.

How long do air conditioners last?

Though AC makes and models can vary, the average air conditioner lasts for about 10 to 12 years. If properly maintained and cared for, it can last a little longer.

Why is my AC making strange noises?

Outside of a low hum when turned on, your air conditioner shouldn’t make a lot of noise. If you keep hearing clanking or screeching sounds, there might be something wrong with your blower or a part might have gotten loose.

It’s important to have a professional check, so it doesn’t damage your AC system.

What Our Customers Are Saying

"Adam Bunch and Salwan were our technicians. They were very professional, courteous, thorough, and we feel they did a very good job. They were both very personable, friendly, and genuinely take pride in their profession. We feel very confident in the work that they did. We have an older home built in the mid 1980s with old, failing hex water lines along with some copper fittings. We needed new lines installed and they did a good job with it. I would recommend them to other people. In comparison, the price is more expensive than some other businesses in this area for the same work, but we feel that the guarantee that comes with Pipe Wrench work brings accountability. We will use this service again in the future."

Amy C.

"Very timely. The first time I used this service I had a thermostat replaced in my hot water heater. They were quick and professional and was fairly priced. I'm in the middle of my second experience at a relatives home for hot water heater replacement. They were able to get a tech out for evaluation the same day we called (today) about a problem and have scheduled the replacement for the next day. The tech was polite, professional and advised us of all our options in a way that was easily understood. I highly recommend Pipe Wrench services."

Sasha N.

"Ryan and Tyler were fantastic! As soon as they got to our home they set expectations for all the work they were going to perform. They kept us posted on the status of the job throughout the time they were working and reviewed everything with us when the job was complete. They were professional, knowledgeable, and nice. I would highly recommend them and the team at Pipe Wrench for any plumbing needs! Although I hope we won't have to use their services again, if we ever have the need for a plumber in the future, they will be the first people we call!"

Katey M.

"They came on time with texts and calls ahead of time to ensure I knew who was coming (with a picture) and when they'd be there. Kyle was professional, personable and didn't try to sell me more than I needed. He worked with the scheduling to get me scheduled that evening, even though I couldn't be there for the install. The installation was prompt and they were clean (again with forewarning and pictures of who was coming). They are my new go to company. Thank you."

Mary W.

"Our technician showed up on time and very professional. This company never tried to take advantage of my older mom. Which some in the past have. Very thorough in explaining everything he did and the cost. They came the very next morning. My mom’s A/C had gone out the day before on a scorching hot day and week. I would highly recommend this company. Very good people."
