I had a job as an assistant for a home renovator.
They have to labor on a narrow budget for some of the condos, and once, they thought that buying a minute-hand quality cooling system would save them currency.
There was a new online a/c provider selling close-to-new quality Heating plus A/C equipment, and there were hundreds of comments from satisfied purchasers. They had a local a/c system service expert who worked with them doing the renovations, so the Heating plus A/C upgrades were no trouble. However, the problem showed up when they decided to trust the unit from the local cooling industry shop. The online a/c business had superb deals for multi-split a/c units, with matching climate control components for each 1, and replacement parts, which they promised were clean and uncompromised. The only way we’d buy new was the filters to ensure the home’s air quality. My associate and I only wanted a truly excellent a/c system that would labor in the Summer and winter without multiple a/c service house calls. The last condition for what my friend and I wanted was that it should not be older than 3 to four years because it was likely that routine Heating plus A/C service would not be enough to keep it working well for long. Long story short, when the a/c worker came to do the upgrade, he found that my friend and I had got a unit that would give the homeowners trouble as soon as it was summer. The shady person who sold it refused to take it back, so my friend and I lost currency that our bosses had to dig into their purses to spend our savings for the mistake. Whatever you do, try to save for another, newer HVAC unit unless you think more about a/c to understand what to check when making the purchase.
