Why Is My Heat Pump Not Cooling?
Heat pumps are a very efficient alternative to traditional central air conditioners. While in cooling mode, there isn’t a real functional difference between a heat pump system and an AC, but during the winter months, the former can also efficiently heat your home, and typically results in lower annual heating bills. It’s also environmentally friendly because it doesn’t require fossil fuels.
However, in the summer months, these two differing systems are very nearly identical. And when your heat pump system isn’t cooling properly, the reasons and repairs are often identical, as well. If you want to maintain optimal temperatures, and you’re experiencing cooling issues or shutoff issues, you’ll want to attend to them quickly, before temperatures become unbearable or repair costs become untenable.
With reputable brands like Trane or Carrier, heat pump and AC repair is streamlined by the hard work of those companies to maintain quality control, but even the best systems can be damaged by poor maintenance.
Things To Check
1. Review your settings and make sure they are correct. Occam’s Razor tells us that the simplest solution is often the most correct. If you weren’t experiencing issues during the winter and autumn, but start experiencing problems once things heat up, check that your thermostat is correctly set to Cool/Auto. Also try fan only, just to make sure that is working well.
2. Check your electrical. It’s good to check the fuse box. It isn’t uncommon for a heat pump system – which draws substantial power – to trip a breaker if something is wrong inside. It could be loose wiring, issues with your own electrical wiring in the home, or a problem with the compressor.
3. Have the capacitor checked. WARNING: this isn’t something we recommend you try on your own if you aren’t experienced. Your capacitor is a sort of battery, which holds a charge in order to run the motors for your fan and compressor. Sometimes these can malfunction or cease working entirely. This isn’t an overwhelmingly expensive repair, and is one of the more common problems we’ve seen.
(As a side note: we don’t want you to think that you’re doomed to have repeating issues. We’ve seen well-maintained heat pumps by Carrier and other top brands run for years with no issues at all! It’s just that in complex systems, there are a lot of things that can go wrong. Fortunately, most of them are very simple.)
4. Ensure you have optimal refrigerant levels. Refrigerant is the magic ingredient in your heat pump system. It does the actual dehumidifying and temperature controlling for the system at large. If you develop a refrigerant leak, it can stop the system from cooling properly or cause it to ice over.
As always, we strongly encourage readers to avoid attempting diagnosis or repair if they aren’t confident in what they’re doing. An experienced eye can save you time and money.
