Plumbing, electricity, heating and air - all of that stuff needs using or it give problems from sitting idle too long.Your insurance needs to be specific for vacation rentals. 

Wowzers...Is it hot in here or is Austin heating up? 

If the market heats up, prices are likely to resume an upward climb.

We have set limits for both heat and cooling so the renters can control it but only within the limits that we set. 

@Xiaoyan Liang I got a quote on just a furnace to have separate heat and it was not worth it.

Electrician: Add baseboard heat to 2 bedrooms, wire electric W/D hookups, wire 3 bathroom vent fans3.

I am doing a flip that has a 480 square foot room off the kitchen, 4 windows, double exit door, sub floor, dry walled, heating vents, electrical outlets.

If the equipment is older than 10 years, I would say stop wasting money on repairs and get it replaced (you may be able to reuse the existing outside compressor it uses R410a refrigerant, but if its R22, it junk).The way they left it, it is not operational for either heat or cooling.Personally, I would review what you paid to the original HVAC company and see how they took advantage of you.

Shipped prices might be higher.I have been catching a bit of heat from moderators lately, but until I get told to stop helping, I will keep on trucking.

However, the house is heated by an above ground oil tank.
