Recently had the upstairs HVAC quit. Called AirMasters. Received call prior to arriving from technician and company administration. Very prompt, courteous and knowledgeable. Decided the parts for the old unit where too costly. Arranged for AirMasters to provide quote. Purchased new efficient unit. Professionally installed. Very courteous and polite technicians installed unit as promised. Arrived on time. Techs were very mindful of keeping house clean during installation. Exceeded expectations. Had a walk through with sales agent to ensure satisfaction. Would recommend and use again with no hesitation.
