Yes it will, this happens often for homeowners. Make sure to check your filters monthly. If the filter is dirty it can restrict air flow and make your A/C not work. If the filter is clean and the A/C is still not working properly there could be a bigger problem. You can purchase air filters on our website. If you are having problems with your A/C unit and have checked the air filter contact Bartlett Heating and Air today to have our professional diagnose the problem for you!
