Customer feedback is mixed. Positive reviews note clean installations, improved comfort after full-home window replacements, and satisfaction with sliding door work. Critical reviews cite deposit disputes and difficulty reaching the company after estimates. Prospective customers may wish to confirm timelines, payment schedules, and communication expectations before starting.

Ive been shopping around for 4 years to get new windows because we lived like if we had no windows always cold in winter, always hot in summer and after Allen and his team replaces all windows and sliding door we slept like kings no more frozen toes or kids coughing with iciles down their nose. A.R windows are budget friendly, hardworking and amazing they finished 7 windows and sliding door in one day they got a cool system its fantastic.
