Heat Pump Repair in Modesto, CA 95358

“My day started with Shawn coming out to check our unit out due to continuous breaker tripping. He found a issue with with the unit that would be a very expensive repair due to unit being 20yrs old. He was very honest in the cost of the repair as well as the risks involved. Shawn then recommended that Dinarte come out to give us an estimate to replace the whole unit.
Dinarte came right out within 2hrs.
He was very nice, listened to our concerns and then looked at the potential job. Upon completion of his process and delivery of the quote we were very pleased that the quote came back less than what we expected.
We will be replacing our unit hopefully soon and would highly recommend Vally Air to anyone needing work done.”

thermostat on or auto

Video – Should I Set My Thermostat to ON or AUTO?

December 31, 2021

On most thermostats, you can choose between On or Auto for your fan setting. On tells your HVAC unit to run its fans all the time, even when the air isn’t being heated or cooled. Auto means the fan only runs when your air is being treated. It might be a good idea to try a combination of both settings. Try setting it to ON when you are home and AUTO when you’re away. For more information, give us a call at 209-524-7756.

What Is Short Cycling?

December 8, 2021

Short cycling is a term used in the heating, ventilation, and air conditioning (HVAC) world to explain a situation where a furnace or air conditioner turns on and off too frequently. The “short cycle” is the period of time that your HVAC equipment is actually running, and the shorter this cycle, the harder your system needs to work.
