Mobile Home Air Conditioning

Manufactured home air conditioning


Air conditioning in mobile homes is usually installed by an independent air conditioning contractor, although some dealers have their own crews to do this. Service calls about water in the heating ducts are not uncommon and mean the drain for the condensed water is not working properly. If you have taken the time to keep a record of who did the AC work you will know who to call. Note that for those in dry climates, air conditioning is a completely different matter from evaporative (swamp) coolers.

Especially if you live in a hot climate, old air conditioners will probably cost you more than they save. Newer units have much higher efficiencies. Old units wear out and cool poorly for the same power cost. A replacement may be expensive at first, but it will likely pay for itself.

One very fixable failure is if the compressor fan fails. This is pretty common. As the fan ages, you may notice that the air conditioner kicks on frequently and doesn’t seem to cool well. As the problem worsens, you may hear a ‘clunk’ sound from the compressor unit when it turns off. This is the thermal overload switch shutting off the compressor before it overheats even more. Ignoring a failing fan for too long may leave you with no choice but to replace the compressor as well.

Window units may also provide an effective means of cooling a hot end of the house. They are relatively inexpensive compared to a system for the entire house, but you will want to consider a few things when using one. Condensation is one issue. Make sure the drain is clear and that it drains safely away from the house to prevent water damage. Also, these units can pull significant amounts of power. Adding an air conditioner to an already-loaded circuit may trip a circuit breaker.

My mobile home is 14 years old and the heating/cooling is going to need to be replaced. I’ve been reading about the various seer recommendation and know that a mobile home unit is different than for a stick-build. I would like your opinion on updating the unit (currently a 10 seer) and the investment into the home…
I’ve spent two winters in the home and while it’s not drafty when the unit is off it quickly gets cold and quickly gets hot depending on the weather… so, what would be the most logical seer number? If I understand correctly, if the instillation of the unit isn’t done correctly or if the house isn’t well insulated it negates the efficiency of the unit, right? I need a new unit but I don’t want over kill if it isn’t going to be a good return on investment or be negated by structural and installation issues.
I’m strapped for money (like most of us) and can’t add other updates on top of a new unit (like better insulation)… suggestion, help, advice?
I need a new unit and I’d like to lower my utility costs but I don’t want to put
Oops, sorry about that last line, poor editing on my part… also, I have a “split system” if that helps you answer my questions. Many thanks!
