A concerned homeowner asked me: “Why is my Carrier heat pump not working properly? It shuts off periodically, or trips the breaker, or just blows warm air.”
We hear this complaint from time to time. Heat pump systems are efficient and growing in popularity. Especially in temperate climates, they present an environmentally and fiscally friendly alternative to more traditional heating and cooling systems. Furthermore, the technology is advancing quickly, and systems are getting more and more efficient and powerful.
Still, with any complicated appliance, there are a lot of moving parts, a lot of things that can go wrong. If you’re experiencing problems, particularly with the cooling abilities of your heat pump system (Carrier or otherwise), this article will give you a few things you can check, or ask your HVAC technician to diagnose and repair.
Disclaimer: DO NOT attempt any repair that you do not feel fully prepared to carry out safely. Heat pumps carry high voltages!
Question: Is your refrigerant level where it should be?
If your refrigerant levels are low, your heat pump system will work poorly, or not at all. It can cause interior workings of your system to freeze or shut off, and is caused by a leak somewhere in your system. If you suspect this to be the case, call a technician. Refrigerant can be hazardous, and only a certified professional should attempt this repair.
Question: Is your electrical working properly?
If your system shuts off periodically, blows a fuse or trips the breaker, it’s a sign of an electrical problem. You should NOT reset the breaker and continue running the system. Heat and cold can cause wires to contract and expand, loosening them over time.
You may also have a problem with your home wiring, or not be providing enough power to your heat pump. This could also mean a compressor problem, which is likely if your system works only intermittently, and is not tripping breakers.
Question: Did I check the system settings and batteries?
Most modern thermostat systems use batteries. Check these – sometimes it really is that simple. Also, make sure your system is set to COOL and that the temperature is set at least two degrees below the temperature in the room.
Other potential problems that can cause those symptoms include a bad capacitor, debris buildup in the external unit, ice inside the system because the defroster hasn’t been running, or dirty air filters. As with anything, routine air conditioning service is your best friend to keep your heat pump system running properly.

This is not a DIY article, a life hack or pro-tip collection, or a jargon-filled tech manual. This is a simple breakdown of easy AC maintenance tasks that anyone here in New Port Richey can perform, meant to keep a central air conditioner in tip-top shape, prevent AC repair problems, and keep it running for years.
Many people assume that only AC company technicians are capable of performing maintenance, and often that is true; I would not recommend that an untrained professional get under the hood (so to speak) and start messing with the innards of their air conditioners in any way.
High voltage, hazardous refrigerant, and a complex assortment of wires, motors, blowers, and coils present a serious deterrent to anyone who hasn’t trained for that kind of thing.
However, there are a few obvious things that every homeowner should be doing to keep their systems running. These are the AC maintenance equivalents of oil changes or fluid top-ups on your automobile. Wear and tear, along with buildup of unwanted debris and dirt, present the biggest danger to a central air conditioner.
Here are three extremely simple things that you can do:
1.Keep the outdoor unit clean. Weeds, grass, bushes, trees, branches, ivy … anything that wants to grow near your outdoor unit should be kept under control. You want a couple of feet of clear space around the casing, and you want to make certain that nothing is getting in there that shouldn’t be.
More elaborate cleanings can be a part of your AC company’s seasonal or annual checkups, but you’ll be doing yourself a huge favor if you just make sure nothing is growing over your outdoor unit.
2.Program your thermostat (or get a programmable thermostat!). The amount of time an air conditioner spends running has an effect on it. If it’s been sized correctly for your home, it won’t need to run all the time. A programmable thermostat will help by ensuring that your preferred optimal temperature is maintained at all times.
You can program it to allow the temperature to rise a bit while the home is unoccupied. Overall, these things pay for themselves very quickly, and help keep the system from working too hard.
3.Clean your filters and grills. You want clean air to be circulating. The way to ensure that is to clean or replace your air filters every month or two, and to vacuum or clean your return vent grills to prevent obstructions. Your AC repair company or owner’s manual will tell you whether your filters are reusable or disposable.
Performing these three tasks regularly is a sure way to reduce the number of AC maintenance calls you’ll have to ask for each year here in New Port Richey.

There are a number of things that can contribute to or cause the presence of ice inside your New Port Richey central air conditioner. If you see ice forming in or on the outside lineset or interior unit, it is a sure sign that there is a problem within. You should reach out to your AC company if you aren’t up to a little investigating yourself, and prepare yourself for the possibility that an air conditioning service is required.
When it’s humid outside, it isn’t uncommon for water to be coming out of the central air drainpipe. Water develops within the unit normally, due to vapors condensing within during the cooling process. It works much like the condensation that develops on a cold can of soda.
But when you start seeing ice instead of water, you may be in trouble. Ice can seriously damage your system from within. The first step in this situation is always to turn the unit off immediately, before the situation worsens and costs you a great deal of money.
What is causing this ice to form?
There are a few possibilities. The most likely culprit is low refrigerant due to a refrigerant leak. Refrigerant is the part of your system that does the actual cooling and dehumidifying. When you don’t have enough of it in the system, contrary to what most people thing, the coolant inside the unit will actually get colder.
The unit won’t be able to do the job of cooling the actual home, though, as the coils will freeze over and the ice will insulate them. If left unchecked, this can cause serious problems. A New Port Richey AC company should be consulted as soon as this is detected, to come in, find the refrigerant leak that caused the issue, seal it, and replace the lost refrigerant.
Another suspect is a dirty or dislodged air filter, which can block airflow within the unit. When this happens, cold air circulates too slowly inside the unit, which again causes the coils to freeze. Switch the system off and replace the filter with a clean one.
You should also have an air conditioning repair service come and inspect it to make sure that the dirt hasn’t gotten to other parts of your unit. If they have, you could see freezing still, as a dirty evaporator coil can freeze and put the entire air conditioner at risk.
If you see ice, do not continue operating the air conditioner. It will damage compressors, gulp down electricity, and do a pretty terrible job of actually cooling things down. Instead, call your air conditioning service and tell them what’s going on, before it’s too late.
