For Aircond make sure HP is more than sufficient, and if can inverter. My first home, i dont have much money.. so buy the cheapest.. actually 1.0hp not enough and aircond have to work harder to cool down the room/space. Second home i can afford better ones, 2.0hp makes a big difference, cool down very fast. Also getting more tried and tested brands like panasonic can save money in long run although more expensive initially.
