We’ve answered some of the FAQs from our customers to help you understand and troubleshoot some heating and cooling issues before you seek professional help.

Air conditioner installation is complex, with no room for errors. That’s why it’s important to hire a qualified and reputable AC installation contractor for the task. The main steps of AC installation include:
  • Assessing your current cooling system and requirements to recommend the most suitable unit for your home.
  • Evaluating the energy efficiency of various air conditioners to find a unit that’ll help you save on energy bells. The U.S. Department of Energy recommends air conditioners with at least a SEER (Seasonal Energy Efficiency Ratio) rating of 13. Consider a unit with a SEER rating of 16 or higher if you want to save more on your energy costs.
  • Choosing the right unit size. You don’t want to choose a too-small or too-large unit to ensure optimum efficiency.
  • Choosing the right type of air conditioner. You can choose either a central air conditioner or a ductless mini-split system, depending on your needs and budget.
  • Choosing the right locations for your indoor and outdoor units.
Each type of air conditioning system has its pros and cons, and the ultimate choice depends on personal preference. While central air conditioners are often more expensive to install, they’re more energy-efficient. On the other hand, ductless mini-split systems are less expensive because they don’t need ductwork and also offer impressive energy efficiency.
Several reasons can cause your cooling system to stop circulating cold air, including:
  • Leaking or low refrigerant
  • Dirty or clogged air filter
  • Defective condenser or evaporator coil
  • Clogged or blocked registers
  • Faulty thermostat
A qualified technician from Davis Heating & Cooling can examine your unit to find the actual problem and recommend a long-term solution.
Several issues can cause your heating unit not to blow hot air regardless of the thermostat setting, such as:
  • Check the red emergency switch plate it should be ON
  • The gas supply is off.
  • The thermostat setting is incorrect.
  • There’s no power supply to the furnace.
  • The pilot ignitor is dirty or clogged, causing the furnace not to ignite properly.
  • You have a wiring problem, such as loose connection, aged wires, or frayed wires, which can cause the thermostat to lose connection to the heating system.
When your heating system blows cold air, you could be having an overheating problem. Most heating units have a safety feature that shuts the system off when it overheats. This function helps prevent carbon monoxide leaks, a fire, or an explosion.
You can tell if your mini-split system is low on freon by looking out for the following signs:
  • Frozen condenser coils
  • Liquid dripping from the system
  • The unit is not working as intended
Don’t hesitate to call a technician if you have a refrigerant issue.
All of our technicians are properly trained on how to accurately repair your heaters and air conditioners so you can rest assured the work will get done right.
