If you suspect that your heat pump is frozen, there are several signs and steps you can take to address the issue. Here are some indications that your heat pump may be frozen and what you can do about it:
Signs that Your Heat Pump is Frozen:
-
Ice Buildup on the Outdoor Unit:
- If you notice a significant amount of ice or frost on the outdoor unit (the condenser), it's a clear sign of potential issues.
-
Reduced Heating Performance:
- A frozen heat pump may struggle to efficiently heat your home. If you experience a decrease in heating performance, it could be due to ice buildup.
-
Strange Sounds:
- Unusual sounds, such as hissing or banging, can occur when ice is present on the heat pump.
Steps to Take if Your Heat Pump is Frozen:
-
Turn Off the Heat Pump:
- If you notice ice buildup, turn off the heat pump to prevent further damage. You can do this at the thermostat or the circuit breaker.
-
Allow the Ice to Melt:
- Let the heat pump thaw naturally. This may take several hours or even a day, depending on the extent of the ice buildup and the weather conditions.
-
Check Air Filters:
- Dirty or clogged air filters can restrict airflow and contribute to the freezing of the heat pump. Check and replace the filters if necessary.
-
Inspect and Clean Coils:
- Examine the coils on the outdoor unit. If they are dirty or covered with debris, clean them carefully using a soft brush or hose. Dirty coils can impede heat exchange and lead to freezing.
-
Clear Surrounding Debris:
- Ensure that the area around the outdoor unit is clear of leaves, snow, and other debris. Good airflow is essential for proper heat pump operation.
-
Check Refrigerant Levels:
- Low refrigerant levels can contribute to freezing. If you suspect a refrigerant issue, it's best to consult with a professional HVAC technician.
-
Inspect and Repair Insulation:
- Check the insulation on the refrigerant lines. Damaged or missing insulation can contribute to freezing. Replace or repair insulation as needed.
-
Regular Maintenance:
- Schedule regular maintenance for your heat pump, including professional inspections and cleanings. This can help prevent issues that lead to freezing.
-
Consider a Defrost Control System:
- Some heat pumps come with a defrost control system that automatically detects and melts ice buildup. If your heat pump doesn't have this feature, a technician can advise you on whether it can be added.
If, after taking these steps, the problem persists or if you are unsure about any aspect of troubleshooting, it's advisable to contact a qualified HVAC technician for further assistance. They can diagnose the issue and perform any necessary repairs or adjustments to ensure your heat pump operates efficiently.

I have used Twintech many times over the years. They always arrive quickly and get the issue fixed. The most recent incident was when my air conditioner broke last week I called Greg at 11:30am and he was at my home by 2:30pm he had the unit fixed by 3:30pm. Twintech are very reliable and honest and they are experts in the field. I have already recommended them to many of my friends. I would not use anyone but them for my heating and air conditioning issues.

I would highly recommend these guys, professional, fast and competitive pricing. I moved into this place with no working AC unit with a 8 month baby, he was able to come with in a week to fix even in the busy summer days. He really values his customers , I am already recommending to my neighbors.

Very impressed they arrive to quote even though I had forgotten to call them back to confirm date & time. They showed the day before installation to deliver the unit. Returned the next day as promised at 9am. Project was completed in a professional manner. They even fixed a few things that they noticed were not installed correctly, or to code by previous heating & air contractors we had at our residence before. Would recommend this company to everyone!

Greg removed old oil furnace and oil tank from basement relocated new Napoleon propane furnace to allow duct work to be rerouted to a much more suitable location. Moved air conditioner to the new furnace. Dave recommended two available grants to assist with cost. They kept to their original quoted price which was substantially lower than a competitors for the same furnace and work. They completed the work as stated when stated and left the area clean and tidy. We are very pleased with the outcome.

We had Grant and Greg Dainty quote to replace our 20 yr old furnace. I have known them for years and have had other jobs done by them ( AC and Pool Htr). The price was very reasonable and the job was completed in one day.

TwinTech was the right choice. Our consultation with Dave set the tone. Professional and knowledgeable, we even received a follow-up call within hours of our install completion, wow! TwinTech arrived as scheduled to install our A/C unit. Within minutes of arrival Greg noted and explained a few out of code faults on our furnace installed by another company, problems fixed, thanks TwinTech. Greg, Grant and "Subaru" Pete were meticulous start to finish. Highly recommended!

Twintech replaced our aging +20 yrs old Furnace & AC with the variable high efficiency Napoleon Furnace matched with the Goodman AC. Sales guy ,Dave was great, gave a no pressure estimate, explained about the Government Rebate program which they took care of completely including arranging the home energy audit. On the scheduled day Greg and his team arrived on time, did a great job and completed the same day , extremely professional and courteous, cleaned up everything , tested the system, Greg took his time to explain the setup. Very impressed with the Napoleon Furnace 9600 which did a great job in maintaining a comfortable temperature last winter and now with the hot weather the Goodman AC cooled the house in much less time than the old AC unit could ever. From start to finish Twintech were great and have no hesitation in recommending them 100%.

The Twintech team did an excellent job installing our new Goodman air conditioner. They were polite and professional. Greg was knowledgeable and clearly experienced. Thank you Twintech for bringing our cooling system up to current regulations. Job well done!

Dave from TwinTech was very knowledgeable, professional and thorough in the buying process. He helped us to identify the best furnace for our home and our budget. When we needed a new filter a year later and seemed to have a problem finding the right one, I called Dave up and he delivered a filter to me the next day! The cost was on par with other retailers, but it was this unexpected personal service that really was impressive. The furnace? Works like a charm.
