I 've been in our house for 15 years and it is hot water heat with and add-on AC unit in the attic. I've never had it serviced and I've never had any problems. I clean the condenser and check the drains regularly.

I've been wondering about having a "Tuneup" performed but not sure if it really provides any benefit or is just a sales opportunity. (AKA a free brake inspection when you get new tires.)

I'm a big believer in "If it ain't broke don't fix it." But that doesn't always work, like motor oil.

Any thoughts? Thanks for any input.

maintenance is necessary but you can do it yourself- filters, keep condensate lines clear, condenser coil clean, inspect blower for dust/dirt buildup.

measure temperature difference across air handler at normal indoor humidity, check capacitors (knowledge and meter required), electrical connections.

Checking the refrigerant charge regularly is unnecessary unless a problem is suspected - it's actually harmful due to loss of refrigerant and risk of contamination every time gauges are applied.

The cheap tuneup specials advertised at the start of each season are usually ways to get their foot in the door and sell something.
Unfortunately residential hvac is becoming very sales focused. With poor mechanical training, sacrificed for training in selling parts and equipment. We call them sales techs.
That said maintenance is required for both heating and cooling.

If the house is a comfortable temperature at show and tell time , how many prospective buyers will look at or even mention the HVAC system? 1 in 10 might be over estimating but 10 in 10 will take a serious look at the bath(s) and kitchen.



You've done a good job so leave it.
