An air conditioner repair costs between $150 and $650 on average. However, depending on whatever element is broken, the repair cost might be $4,200 or more, especially if a full replacement is required. The type of air conditioner you own can influence the cost of repairs. For example, you'll almost certainly pay more to have central air conditioner parts repaired, which can range from $100 to $4,200, than to have your window air conditioner repaired.
A well-maintained central air conditioner will typically last 10 to 15 years, whereas a window unit will last 8 to 10 years. The longevity of your air conditioner can be affected by factors such as unit quality, environment, maintenance, and usage patterns. Regularly cleaning the filters, keeping your outdoor unit clear of dirt, and having yearly service checks will all help your AC last longer.
Most indoor air quality problems arise from indoor pollution sources (such as fuel-burning combustion appliances and tobacco smoke) emitting gases or particles. Inadequate ventilation fails to eliminate pollutants or introduce sufficient outdoor air, allowing indoor pollutant levels to increase. Elevated temperatures and humidity can further raise concentrations of specific contaminants in the indoor environment.

(3-5) Amen ONLY. Possible callback, 90 day warranty technically expired on 3/20/25. Spoke with David. He had called when his C/S faucet install was still under warranty to get the handles straightened out, as he wasn't fully satisfied with the original install. He stated that Amen convinced him that no adjustments needed to be made at that time. He now says that the handles are farther off and NEED to be adjusted now. He DOES NOT want to have to pay for service since his initial complaint was within the warranty timeframe.

12 - 2. Spoke to Christine. Loud sound coming from pipes underneath the house. She called us in February for this as well... the tech that went said that: could not hear any plumbing noises at this time. The only noise was from a street sweeping truck that passed by multiple times while on site and was in neighborhood yesterday when on site (sounds to tech like water pipes humming when far away). Checked pressure and verified at 40psi. The only corrections the tech can recommend are pressure expansion tank, pressure relief valve and temp and pressure valve on water heater. Possible toilet flush valve issue but that has never been heard while on site. Also effected by no expansion tank. Not sure if any of this s related, but just FYI. Please check this out, provide pricing before performing any work!!
