Here are some of the most frequently asked questions about AC, heating, and electrical systems that we hear from our customers.

A leaking air conditioner is usually a sign of a clogged drain line. When your AC works properly, it expels condensed water through the drain line. Over time, the drain line can become clogged with dust, debris, or even mold. When your drain line clogs, the water cannot move through and is funneled back into the AC unit, causing the leak.

The evaporator coils inside your AC can freeze up when there is insufficient airflow or a refrigerant leak, causing ice to form around the coils. Dirty air filters, a broken fan, or debris around the evaporator coils themselves can create this issue. It can be difficult to determine the cause of frozen evaporator coils without an experienced technician to assess your AC unit. Call Doctor Home Experts for a prompt inspection and quote for AC repair in Harris County.

If your furnace is turning off on its own, it is likely a problem with your thermostat. Fixing the problem can be as simple as replacing the batteries. However, if your thermostat is an older model, the wiring might need to be replaced. You should also consider the location of your thermostat. If it is too close to a heat source (near a window with direct sunlight), the temperature reading can be too high. The skewed reading may cause your thermostat to turn off automatically.

If your heater is suddenly blowing cold air, it generally means that the system is overheated due to:
  • Insufficient airflow due to clogged filters
  • Mechanical failure
  • General wear and tear
Once you notice your heater blowing cold air, call our trusted technicians to check your heating unit to diagnose and fix the problem.

Yes, you can replace your breaker panel without a permit. However, keep in mind that this can be dangerous if you do not have the skills or experience to do so safely and correctly.

There are many reasons why an electrical outlet can suddenly stop working, such as:
  • A tripped circuit breaker
  • A blown fuse
  • Loose wiring inside the outlet
  • Insect or pest damage
If an outlet in your home stops working, shut down the circuit breaker immediately before determining the cause.

Getting routine maintenance services for your HVAC system helps keep it in top shape and spot any potential issues quickly. As a rule of thumb, you should get your furnace and AC checked out once every year, even if there are no obvious problems. Doctor Home Experts offers several membership plans to make scheduling maintenance easier. With our Doc Plan, you save 10% on the cost of an annual safety check which includes:
  • An arc fault breaker test
  • Ground fault receptacle test
  • Free panel inspection
  • Energy consumption test

To ensure that your HVAC filters are clean and sanitary, you should replace them every 60 days. If you are living in a home with lots of dust or pet dander, replace the filters every 30 days to maintain air quality.
