Surprisingly, 50% of HVAC system failures are the result of improper or inadequate maintenance caused by the users themselves. But why Americans choose to maintain their own HVAC systems? The most common reasons cited by customers of Alpha Mechanical, a Sacramento AC installation company, is cost savings, the seeming simplicity of the HVAC tasks, and flexibility in managing their time. However, the consequences of this complacency can include heat stroke, dehydration, and heart attacks in people who were expecting cooler temperatures and were instead met with overwhelming heat.
Okay, let’s say you have the right hands to maintain your home’s air conditioning system yourself. To prevent potential problems from your DIY enthusiasm, experts recommend dividing HVAC-service tasks into those you can do yourself and those that require professional intervention. Understanding your do-it-yourself options will definitely keep you away from risks and unnecessary expenses. Below, we detail where your DIY competence begins and where it ends.
Basic tasks you can do yourself
“Changing the filter is the easiest way to improve the performance of your HVAC system without calling a contractor,” – agree the pros at Alpha Mechanical, whose expertise has been honed in Sacramento’s temperate climate. In fact, you can do some air conditioner maintenance work yourself. Take it as the point at which your competence begins: changing filters, cleaning grilles and checking the thermostat. The first step to enhance your competence is understanding how frequently filters should be replaced. This depends on three key factors:
- Type of filters: They come in charcoal and catechin. They are designed to last 3-5 years by the manufacturer.
- Air quality: The lifespan of an air conditioner can be shortened due to air quality. For example, in Sacramento, where the air is dry and dusty in the summer, which causes the filters to be replaced more often than the manufacturer suggests – once a year.
- Intensity of use: The average AC unit is designed to run continuously for 15 minutes with 5-minute breaks, but no more than 8 hours per day. Exceeding these operating standards shortens the life of both the entire HVAC system and its individual parts, such as filters.
Cleaning the grilles is the second easiest task you can do yourself. This part may also include checking that the vents are not blocked, for example, if unauthorized people have access to the vents in public areas.
The most difficult task you can do yourself is to check the thermostat. Start by checking the power; make sure the unit is properly plugged in. When the thermostat is turned on, check the thermostat’s display is working properly, without flickering. Another check is the thermostat’s operating modes by switching the unit between heating and cooling modes, and make sure there are no strange noises or smells. Finally, run tests: use a multimeter to check the voltage at the thermostat’s outputs if you suspect an electrical problem. Remember, your job as a DIYer is to check the HVAC system to make sure it’s working properly; as a last resort, replace the filter rather than repair anything. If the system is unresponsive or there are other problems, you definitely need the help of a professional.
When to throw up the white flag
If DIY hasn’t helped and your HVAC system continues to make strange noises, not cooling or heating, these are sure signs that it’s time to seek outside help, such as contacting a professional. He or she will quickly diagnose the problem and save you from playing the guessing game.
The Pros’ Scope of Expertise:
- Repair or replace HVAC components: When the fan motor stops or the compressor wheezes, that’s where your DIY project ends. From that point on, only professionals ensure proper installation and compatibility of HVAC equipment.
- Safety issues: Heating elements, electrical components, and refrigerant lines require experience. Improper handling of these parts creates safety hazards and voids warranties.
- Service contract support: Professionals ensure compliance with manufacturer and regulatory operating requirements – this is how experienced technicians protect your investment.
Arguments for professionals
The accuracy and experience of professionals are undoubtedly the most important arguments in their favor. HVAC technicians have the diagnostic tools, knowledge, and experience to effectively identify problems and save you time and hassle. Experts go even further to optimize system performance by preventing premature wear and tear on individual parts. As a result, properly maintained systems last longer.
On the contrary
Now, you may use the final objection: “Professionals – they are expensive.” As the numbers don’t lie, consider this: A typical service call from Alpha Mechanical, the already mentioned team of certified technicians in Sacramento, typically costs between $75 and $150. Their service includes the air conditioner and heat pump inspection and tune-up, as well as duct inspection and cleaning. Alternative: The cost to replace an HVAC system due to your DIY indiscretion will set you back between $5,000 and $10,000 (Forbes Home). You don’t need a calculator to figure out the better deal.
Conclusion: Maintain a balance between DIY and PRO
Imagine your HVAC system quietly humming away, diligently maintaining your home’s climate – it’s a given, and you can assume it’ll run smoothly forever. But like any machine, your HVAC system is going to break down occasionally, and more often than not, it needs to get serviced. So when should you roll up your sleeves, and when should you call in the pros? The above is the limit of your do-it-yourself expertise you can afford. Going beyond that puts you at risk.
Yes, do-it-yourself HVAC maintenance can be attractive because of the cost savings and apparent independence. But there are drawbacks to this approach, and only a balanced strategy can provide the right solution. To keep it clear, do simple tasks yourself, and don’t hesitate to call in the professionals when needed. They have professional equipment and experience. By letting pros handle problems beyond your DIY expertise, you’ll save money, improve your system’s performance, and avoid costly mistakes. Agreed?
