Most of the time, if you are going to have AC maintenance performed by an HVAC technician, you are probably going to have it completed in fall and/or spring. It is uncommon to request this maintenance in summer, right at the peak of the hot season. However, there are some reasons why completing A/C maintenance in summer might be a good idea.
You Suspect That the Hot Weather Is Impacting Your Air Conditioner
Air conditioners work very hard to keep things cool and comfortable, especially in temperatures that are in the nineties or above one hundred degrees. During a heat wave, when the outside air is suffocatingly hot, your A/C works overtime. This could mean that your air conditioner could overheat, which would result in a dead air conditioner. If you request A/C maintenance at this time, your HVAC technician could spot that trouble before it starts, and prevent that situation from happening. It would save your air conditioner and your wallet (and possibly your life) at the same time.
Nobody Else Is Requesting Maintenance Right Now
As previously mentioned, most people have A/C maintenance performed in spring or fall. They do not typically do it in summer. Ergo, you could easily find an available HVAC technician to do the maintenance, and you might even score a discount for completing this annual task early.
The Maintenance Is for Your Vacation Cabin/Summer Residence
A vacation cabin or summer residence is not one you are at or in regularly. As such, you tend to do maintenance when you are actually present in this second home. Calling an HVAC technician to do A/C maintenance on your cabin in the summer is not out of the ordinary, and it makes perfect sense. Your cabin is then comfortable for the time you spend there, and it will not need maintenance again for another year.
The Primary Services Provided for Summer Maintenance
The primary services provided for summer maintenance of your A/C unit typically cover the unit's ability to function properly. It may also include refilling refrigerant, looking for leaks, and replacing parts that are worn out. In the case of a cabin or seasonal residence, the technician would also be looking for problems caused by pests and address those problems if they are present (e.g., chewing of wires, broken condenser cover, etc.). Some of the services necessary to survive the winter may also be included with the summer maintenance package.
