Cases of hot and cold spots in homes have been quite common especially among homeowners who do not have frequent HVAC inspections and servicing. When the hot and cold spots appear, some of the homeowners get frustrated because they do not know what is happening. If this is you, then keep reading to understand the probable causes of this problem.
The ductwork can best be defined as the path taken by your heated or cooled air to get to your open spaces and rooms. It is recommended that the ductwork remains sealed in order to prevent any loss or leakages of AC or heat.
When poorly insulated ductwork may suffer from efficiency problems. The ducts will start radiating heat and cause heat loss or they absorb heat during summer and cause your cooled air to heat up.
All household equipment is vulnerable to breakages. The same applies to HVAC system components and when this happens, their cooling and heating efficiency may be affected causing hot and cold spots.
Most modern homes have heating and cooling units that are connected to a programmable thermostat. This is important in controlling indoor temperatures. However, if the location of the thermostat is not ideal, then there can be inconsistencies in temperature readings and a wrong message may be sent to the HVAC unit.
For instance, a thermostat which is located in direct sunlight may return a higher temperature than that of the room. This may result in addition and unnecessary cooling and higher bills.
Solving the Hot and Cold Spots Problems
There are several ways you can solve the cooling and heating problems among them:
Fixing Your Ductwork
A HVAC professional can help you check the ductwork to ensure it is properly sealed and no damage is on the surface of the ducts. Also, ductwork connections must be properly sealed with metallic tape to ensure no loose pieces.
Proper Equipment Maintenance
Having a preventive maintenance contract will ensure regular servicing of your HVAC equipment thus detecting any faults immediately. It is important to have a maintenance exercise just before a season begins as this will help your system build capacity and resilience for the coming season.
Relocating the Thermostat
Where the thermostat is suspected to be the problem, it should be relocated to another place where the readings are likely to be accurate. Be sure not to place the thermostat near an insulated areas or direct sunlight.
If you still have problems even after going through the above issues, the problem could be much bigger and as such the best advice is to consider zoning your system with the help of a reputable and experienced HVAC professional.
