Here's the reality: most large home service companies, ie electricians, plumbers, renovators, etc. are going to be significantly more expensive and lower quality work than your small business types. You're paying for convenience. If you're a homeowner, it's a really good idea to be proactive and find the good, local businesses for these things.

I needed an electrician recently and thankfully my neighbor just had some work done by a guy who lives down the street from us. If I didn't have him, I would've been stuck calling a big company and paying out the ass. Instead a local guy charged me $195 for an hour of work and some parts. Previously, I had to use a bigger company who charged me $400 for similar work in 2019.

Ask around for a local HVAC person to come give your systems a tune up. Find excuses to get a plumber or local electrician into your house. Then when something is wrong, you're a repeat customer for someone you found is trustworthy.
