During the hot summer months, our team is hard at work ensuring that San Diegans are able to stay cool and comfortable in their homes. In most cases, the central ac unit can be replaced by our team within 1 day, or the same day.

 

"We just moved in our new home and (bummer)- AC wasn’t working. Nester helped us with our ac repair and, when we decided to replace the unit for upstairs, installed a new air conditioner the same day! So far everything has been working perfectly. Their rates were also significantly lower compared to 2 other contractors that we called out to give us an estimate. Will definitely recommend!"

"Our HVAC system in our home has been on the fritz since last year, but we’ve been putting off the repair for awhile. We called around to several different companies for a quote on a new ac installation. Out of the 4 or 5 that we called, nester seemed to be the most competitively priced and the most knowledgeable. The whole experience was very pleasant."
