The gas valve is bad and trips the limit

Furnace repair in Mcdonough

 The furnace ran for 5 minutes but will shut off before reaching the temperature on the thermostat. 

You should turn it off and call for service. This could cause other parts to break. The main limit is telling the furnace to shut off due to high heat. The limit could be bad or it's doing its job and it's a bad gas valve or an air flow issue. Aaac service heating and air repaired this on Saturday.

The air conditioner is on but no air flow. Solved

Furnace repair in Mcdonough

This a/c was on outside. There was no air flow. Was it a bad blower? Was there ice blocking the air. Did the duct come loose? Maybe it was a bad capacitor. Was the contactor stuck on? 
The ice was on the system bad but not the cause this time. The thermostat was calling for a/c and contactor was good. The capacitor and motor checked out as good. This time the circuit board was not telling the blower to come on. We had one on the truck. This 24 year old air conditioner is working. Problem resolved fast.

How to Choose the Right Thermostat for Your Air Conditioning System

Welcome to the Aaac Service Heating and Air blog! When it comes to optimizing your air conditioning system, choosing the right thermostat is key. Let's explore some tips on selecting the perfect thermostat for your needs:

1. Consider Your Needs

Start by assessing your HVAC requirements. Do you prefer programmable thermostats for energy efficiency, or do you need a smart thermostat for remote access and automation?

2. Compatibility

Ensure that the thermostat you choose is compatible with your existing heating and cooling system. Check the wiring and voltage requirements to avoid any installation issues.

3. Features

Look for features that suit your lifestyle, such as Wi-Fi connectivity, scheduling options, and energy-saving modes. Select a thermostat that offers the functionality you need.

4. Budget

Determine your budget for a thermostat. While smart thermostats may come at a higher price point, they can lead to long-term energy savings and convenience.
