Came out for cooling maintenance for two systems. Checked both systems they both are low on refrigerant. Ran leak detector and found nothing
Left pricing to add insulation in rolls and blow in for an attic renovation. Customer will get with a framer and get back with us.
Estimate for mini split installed in the garage. No charge
Completed diagnostic, system was set to low speed in cooling mode which was not right. Adjusted blower back to hi speed. Also checked refrigerant level on downstairs, which no problem was found. Recommend having Windows check for possible leakage.
Condenser fan shroud was not secure, rubbing up against the fan, causing system to make noise.
