What Is The Evoheat Evo270?

The Evoheat Evo270 is a popular residential heat pump designed for energy efficient home heating and cooling. It has a high efficiency compressor and fan motor that helps lower energy usage and cost savings. It also features advanced inverter technology which allows the heat pump to modulate heating and cooling output based on the indoor temperature. This results in precise temperature control and comfort.

Evoheat Evo270 Problems

1. Not Turning On

If your Evoheat Evo270 heat pump is not turning on then it becomes a problem because the issue is likely due to;

  • A faulty thermostat
  • Loose wires
  • Dead batteries

Troubleshooting The Not Turning On Problem

  • Make sure that the thermostat is set to the proper mode (heat vs. cool) and that the temperature is set higher than the current room temperature because the heat pump will not turn on if it does not sense a demand for heating.
  • Check that the thermostat is securely attached to the wall and that all wires are firmly connected.
  • If the thermostat is battery-powered, low or dead batteries will prevent the thermostat from signaling the heat pump so you need to replace the batteries.
  • Also inspect the thermostat display for any error messages or fault codes which may indicate issues with the thermostat itself. It is very important to note that if there are any messages or fault codes, you should contact an HVAC technician for diagnosis and repair or replacement of a malfunctioning thermostat.

2. Not Heating

If the Evoheat Evo270 heat pump is not heating then the heat exchanger could be frozen. This happens when the heat pump takes in more cold air than it can heat thus causing ice to form on the exchanger. It can also be due to;

  • Faulty thermostat settings
  • Dirty air filter
  • Lack of proper insulation

Troubleshooting The Not Heating Problem

  • Check the thermostat settings and make sure the temperature is set properly for your needs. The heat pump may be oversized for the space and so causing it to cycle on and off frequently and ice up. You may need to adjust the thermostat to a higher temperature.
  • Make sure the air filter is clean and unobstructed because a clogged filter reduces airflow and efficiency causing the heat exchanger to freeze up so you need to replace or clean the filter.
  • A lack of insulation results in greater heat loss and in so doing overworking the heat pump. But more insulation can improve heating performance and prevent future icing.

3. Refrigerant Leakage

A refrigerant leak in your Evoheat Evo270 heat pump can prevent it from reaching the target temperature. The refrigerant is the medium that absorbs and transfers heat in the system. If you have a refrigerant leakage problem then it may be due to;

  • Faulty components

Troubleshooting The Refrigerant Leakage Problem

  • It is best to call an HVAC technician. They can locate the leak, seal or replace damaged parts, recharge the heat pump with new refrigerant and test to ensure proper operation because DIY refrigerant recharging kits can be dangerous if you’re inexperienced.

4. Drainage Issues

If your Evoheat Evo270 heat pump is leaking water then it likely means there’s a drainage problem that needs your attention. There are a few common causes for this like;

  • A clogged drain line
  • A faulty float switch
  • A damaged drain pan
  • Too much refrigerant

Troubleshooting The Drainage Issues

  • You need to check the drain line for any visible clogs or dirt and clean out or replace as needed.
  • If the float switch is stuck, damaged or malfunctioning it may not trigger the water to turn off thus leading to overflow and leakage. So you need to have an HVAC technician test the float switch and replace it.
  • It is best to have an HVAC technician repair any damaged drain pump components on the heat pump to ensure the proper installation of the new drain pan.
  • You also need to have a technician check the refrigerant levels and adjust as needed. An overflow of refrigerant will also reduce the efficiency of the heat pump so proper charging is important for both preventing drainage problems and having optimal performance.

5. Loud Grinding Or Screeching Sounds

A noisy Evoheat Evo270 heat pump can indicate a problem that requires service. Loud grinding or screeching sounds are often a sign of;

  • Faulty bearings or motors
  • Refrigerant leakage
  • Loose parts

Troubleshooting The Loud Grinding Or Screeching Sounds Problem

  • The bearings or motors that power the compressor and fan can become worn or damaged over time so it is best to have a technician inspect and replace these components.
  • An HVAC technician should locate and repair any leaks recharge the refrigerant and then test the system.
  • Be sure to tighten loose parts and realign or replace any damaged components on the heat pump.

How To Avoid Evoheat Evo270 Problems

  • Check/inspect the air filter at least once a month and clean or replace it every 3 months or as needed.
  • Always check the area around the outdoor condenser unit and remove any debris like leaves, dirt or snow that could block airflow over the heat pump.
  • Look for any damage or deformations in the refrigerant lines which could affect performance or cause leaks.
  • Check the control panel for any error codes then make note of the code and contact an HVAC technician to diagnose and repair the issue.

Why Won’t My Evoheat Evo270 Turn On?

If your Evoheat Evo270 heat pump will not power on then first check that the heat pump is plugged in and the circuit breaker has not tripped. The Evoheat Evo270 needs a 220-volt power supply so make sure the correct voltage is being provided.

Why Is My Evoheat Evo270 Making Noise?

Some sounds from the Evoheat Evo270 heat pump are normal, such as the fan running or the slight compressor noise during its operation. But loud grinding, squealing or rattling sounds can be a sign of a much bigger problem requiring serviving.


If you own one, then it’s very important to understand some of the common problems that can arise with the Evoheat Evo270 heat pump and how to properly address them. While the Evoheat Evo270 is a durable and reputable heat pump, all heating and cooling equipment needs regular care and upkeep, and by following the solutions in this article and staying on top of any warning signs, you’ll be well on your way to enjoying the benefits of your Evoheat Evo270 heat pump for a very long time.
