Newer air-conditioning units typically draw less power than the older ones.
It is not unusual for older homes built in the 1950s or earlier to only have 100 amp service panels rather than the common 200 amp service panels found in later homes.
Either of these could cause noticeable dimming at times as could other major appliances.
New homes and newer appliances should not cause this unless you are using near maximum amperage.
A competent electrician can easily check the majority of electrical connections throughout the house and at the service panel. A competent electrician can also check any/all plugs for proper grounding and proper phase at each wall outlet. You can too if you have a good little meter.
Competent is the key word here.
Typical grounding is done at the service panel where the ground wire is actually connected to the neutral bus. Not sure why exactly but this non-dedicated ground connected to the neutral bus at the service panel is also why grounded components induce more sonic harm than non-grounded. A dedicated ground for your components would definitely be worth considering.
Checking connections from the street to the service panel most likely will require your electrical company to perform this service.
Building a system by laying the right foundation is the only way to go. Electrical is the second most foundational element to a well-thought-out-system.
As such proper line conditioning is mandatory. Again, proper being the key word here because most line conditioners either do nothing or induce their own sonic harm. Moreover, very few will filter out bi-directional noise of which digital noise is. Hence, even if your digital source or amps are attached to good line conditioners the chances are better than excellent that the line conditioner is allowing the digital noise generated by the component to go through the line conditioners back into the wall, all the way back to the service panel, and then induce that digital noise into your other components.
Other things to consider are cryo-treated audio grade wall-outlets, wall plugs, IEC connectors, IEC inlets at the back of the components, internal and external fuses, AC cables, ics, and scs.
Oh, yeah, since I was remodeling a room for listening last year I also had 500ft of 12/2 gauge Romex double-cryo-treated for 4 dedicated lines from the service panel to the listening room.
All of which is relatively inexpensive when compared to the price of one good component. That is except for perhaps the line conditioners.
But since proper AC treatment is one of the two foundational elements to building a well-thought-out system just doing the things mentioned above will produce a pristine and musical system that few can match because of what you did to clean up the AC.
Not to mention you get a bit closer to hearing more of every components' true capability.
-IMO
