Experts from McLay Services Inc. have put together a very handy FAQ guide for homeowners who have important questions about their HVAC system.
1. When should you repair your HVAC system?
Repairing a system is dependent on several factors. Anything approaching or past ten years requires a repair when something goes wrong. If you have cleaned the filter and the problem persists, then you need to call a technician. Weird smells, noise from debris, and anything that requires you to open up your system needs a professional’s expertise. Homeowners who DIY their repairs risk voiding their warranties and further damaging their system.
2. When should you replace your HVAC system?
Replacing your air conditioning or heating system is primarily a question of age and the cost of repair. If your AC repair is too expensive, a replacement with a new unit may be a better option. Generally, any system that is more than 10 years old should be replaced to save on energy costs and to keep up with new technology. Another rule that experts apply is that if you multiply the cost of the repair to the age of the unit in years and you exceed $5000, then you need to replace your system.
3. Is it a problem with the HVAC system or just the thermostat?
Sometimes, homeowners attribute problems with the thermostat to something far worse. Thermostat problems usually involve your unit not fully heating or cooling a room, frequent shutdowns and restarts, as well as temperature problems on the display. McLay experts say a thermostat controls the whole system, and can sometimes make you think that everything is wrong.
4. How do you know if you can trust an HVAC professional?
Aside from checking with the company on their credentials, you can also ask if the professional they send you is NATE-certified. NATE-certified professionals have gone through several exams based on practical experience in their field and are continually educating themselves on how to improve their skills.
