Coming from 40+ yrs experience, even the generic or so-called cheap brands, if installed right, can last you a long time. While working in the field, we’ve seen ‘low end’ air conditioning units over 20 yrs old. Again, what does this mean for you as the consumer? A very expensive air conditioner installed improperly will give you the same problems as another brand that is installed improperly. Some air conditioners are just a plain old DOA (Dead on Arrival). Especially when dealing with electrical parts, you just never know what could happen. That is why warranty is very important when choosing which air conditioner is better suited for you.
Great and up to code installation of your air conditioning and heating system is the key! The importance of installing your air conditioner the correct way cannot be emphasized enough. Granted building codes change from time to time and are different in every region, basic installation rules should always apply. Checking the contractor’s customer’s reviews or asking for them should help in determining if you have a qualified and certified contractor. Some states have a licensing website to check and see if said contractor has had any disciplinary actions incurred in the past.
