Keep Your Indoor HVAC System In Top Shape

Posted On July 31st, 2018 by Lanz HVAC


Before the late summer heat hits, it’s worth giving a good long do-it-yourself look at that vitally important indoor air conditioning and ventilation system - every component from the evaporator, blower and air handler to the ducts, wall intake, drainage hoses and floor registers.


Heed the advice of your local friendly HVAC experts from Lanz Heating and Cooling. Treat your home’s air conditioner or heat pump unit to some extra-careful attention and it should treat you to total in-home comfort the rest of this summer.


Check out our Top HVAC Tips to make sure your indoor air conditioning and ventilation system - also known as an evaporator - is ready to beat the heat:


1. Keep the path of airflow in your home’s ductwork clean and filtered.

It’s a smart year-round homeowner tip to replace (or clean, if it’s the reusable kind) the HVAC filter every couple of months - and even more often after the pollen-filled days of spring. This is a sure way to remove any dirt, fur, soot, and allergy-causing particles floating around the air you breathe. Just slide in a new clean air filter.


As an added bonus, a clean HVAC filter means a more efficient A/C system, which means lower energy bills, which means more summer fun.


Also, give a visual inspection to your A/C’s air intake vent, usually placed on a wall. Remove dust, cobwebs, and debris so it takes in plenty of clean air.




2. Make sure your condensate pan and drainage line are clear.


This is also a great tip you can use all year. Water from your inside evaporator coil can allow algae and mold to grow, eventually clogging the drain. The result is nasty odors, possible water damage and uncomfortably humid air in your home.


Step 1: About once a month, mix a cup of distilled vinegar or bleach liquid (not the gel, and nothing with harsh chemicals!) into 20 ounces of hot water.


Step 2: Turn OFF the electricity to the HVAC unit.


Step 3: Open the drain’s cover panel and pour.


The bleach kills all the bacteria, microbes and algae that may have built up in the drain pan. Your drainage pipes stay wide open and functional, making leaks less likely and allowing your A/C system to do its job of cooling and dehumidifying the air.


Which bleach? Just the regular kind - though our local expert from Lanz Heating and Cooling has a suggestion: “I always tell the homeowner to use lemon-scented bleach. Makes it smell pretty.”



3. Listen for any unusual sounds or noises.


Whirs, pings, thumps and bangs could indicate that your air comfort system’s motors and moving parts are wearing out, such as the fan, compressor or pump.


Experiment with your thermostat device by raising and lowering the desired temperature, and by switching the fan from “Auto” to “On” and back. Make sure the fan kicks on and turns off when it should, and make sure that when you set the temp lower than the outside temp, plenty of cool air is blasting out of all your home’s register vents.


As your HVAC system performs this test, listen closely - you might hear your home’s central air conditioning equipment trying to tell you something.



4. Take a tour of your home or office.


The amount of air being blown through each floor register should be the same throughout the entire house.

Ensure that all registers are installed and can open and close. Remove each register and stick a piece of rubber tubing into the vent. You should feel no blockage at all. Then replace the register.

When homeowners think about their home’s air conditioning, heating and ventilation systems, they often think first about that huge block sitting out in the backyard (the condenser coil). But when you need to know your family will be cool and comfortable at home the rest of this summer, it’s also what’s on the inside that counts.
