I am definitely nowhere near as proficient as I’d like to be with “building science” but am learning as I go along here!

Does anyone have experience with this process or proficient with google sheets? 

I have concentrated my properties in one area and have become very familiar with and proficient in that area.

@Omar Merced I couldn't help but notice that Raphael doesn't seem very proficient with English.

I would use the resources like yellowpages, google reviews, ask at a real estate investor meeting or maybe sign up for Angie's list and find the best HVAC company and installer who, stands behind the product, is willing to educate you on the right equipment and provide you a fair quote.Your investment strategy, and what the standard is in your area will dictate the price.I would look for the Highest seer, with a good warranty 10 compressor, 10 year parts, look for one with quiet technology (compressor sound blanket, motor mounts, Air handler blower motor, air flow designed for quietness) and ease of service for the air filter, air handler coil cleaning, overflow float switch, and access or instruction on drip pan tablets/liquid and drain line cleaning.What I look for in a HVAC installer is someone who is proficient and not on the phone or looking through the manual a lot.  

Then judge technical proficiency as opposed to boasting or marketing hipe.

I was impressed and she seemed very proficient.

I’m looking for a 30 fixed as I get deeper into the BP community and look for my next investment once I’m able to find an area or areas I want to farm and once I get proficient at analysis and making offers.

She’s also one of the most proficient real estate agents in town and is by far the most useful for an investor because she is an investor herself.

In order to make this transition we would like to form a team and connections with great broker, a reliable lender, and a proficient property management with contractors connections.
