Keep Your HVAC System Optimized | Maintenance | Russell & Lemay

Every heating, ventilation, and air conditioning (HVAC) system needs seasonal maintenance! Summer can be hard on your machinery, so inspecting in spring or early summer is the best way to go.  If you give proper attention to your system, it will reduce energy costs as well as maintenance costs in the long run and prevent a major overhaul. Here are details on what inspection professionals look for during seaonsal maintenance. 

Healthy Ductwork

Ductwork is the foundation for proper ventilation in a home, so it needs to be periodically checked to make sure there’s no leakage. Many homeowners forget about ducts, not realizing that leaks can increase energy bills and create poor indoor air quality. Industry experts say that up to two-thirds of American homes have leaky ducts severe enough to warrant sealing or repair work. 

Leaky ducts lead to inefficient energy usage as air can be pumped inadvertently into places such as the attic or garage. Consequently, discomfort in your home may occur due to deficiencies in air circulation. You need to find out if any rust, corrosion or moisture has built up in ducts, as all of these can prevent the system from functioning properly. Pooling water and condensation can also contribute to degradation over time. If left unchecked, these problems can add up to huge repair costs.

Hidden Allergens 

A clean air duct system can reduce or eliminate allergy problems in your home. Conversely, a dirty air duct system can increase indoor pollution and sneezing. Don’t underestimate the mold, dust spores and other harmful elements that can build up in your HVAC system over the course of a year! Studies show these pollutants can directly endanger your health. But, with yearly spring maintenance and cleaning you can easily maintain good indoor air quality.

Circuit Boards and Wiring

In order for your HVAC system to run properly, wiring between the thermostat and AC must be in good condition. When wiring gets old or loses insulation it not only affects electrical performance but can be a potential fire hazard. A technician will inspect the circuit board and relays and test the condition of the capacitors. A relay switch inside a thermostat has a magnetic field that is activated by room temperature to change between lower or higher voltage. 

The reason only experienced professionals should test HVAC equipment is that there is potential for electric shock. If you hear clicking noises in your system, it could mean the relay switches are dirty, worn, or overheated from an overload. Clicking noises may also result from loose wiring, or loose connections between capacitors or relays. If your system is constantly switching on and off, then you definitely need to have it inspected. The quality of your electrical power also plays a role in the performance of your HVAC system. 

Conclusion

Dirt, corrosion and other unwanted buildup in your system can hinder performance of heating and air conditioning. Since debris such as dust, oil and even insects naturally builds up over time, it’s wise to have your system thoroughly checked and cleaned during seasonal maintenance. Electrical components such as contacts, relays, and coils must stay clean in order for an HVAC system to run at full capacity. The more you take care of your HVAC system with routine inspections, the longer it will last!
