Your HVAC unit plays a major role in ensuring your home remains comfortable throughout the year. Can you imagine not having a comfortably heated home as winter draws closer? Like anything else in your home, your HVAC system can encounter problems. From poor circulation to poor smells, here are some signs it's time to call for local heating inspections of your system.


Smells


Do you notice a nasty odor whenever you turn on your AC unit? The heating and cooling system shouldn't have a poor smell. So, if you've noticed a nasty sulfuric odor, rotten eggs, or something moldy, then you have a problem on your hands that a professional must look at. If you haven't had regular inspections or if your unit is outdated, there may be a buildup of dirt, mildew, and mold in your AC ducts. Keeping your home heated or cooled shouldn't mean you have to breathe in nasty odors, as that can impact your overall air quality.


Leaks


Did you know that your AC unit could leak? According to the Air Conditioning Contractors of America, as much as 5 to 20 gallons of condensate drains per day from your AC, depending on its size, how long the unit runs, and the amount of humidity. If the amount of fluid draining out of your unit gets out of hand, you may have water damage.


That's right, water damage doesn't just result from leaks in your roof or piping. It can also come from your AC unit. When water damage sets in, it can be expensive as it can seep into your drywall and breed mold. It doesn't take long for mold to appear in a wet environment. Once it begins growing in your home, your health and property are at risk.


Excessive Noise


When you turn on your AC unit, you should hear a slight humming noise and then nothing at all. However, if your unit is outdated or near the end of its life cycle, it can begin to shake, rattle, roll, rock back and forth, and be distracting. You shouldn't have to turn your AC down or completely off to have a conversation or watch TV.


When trying to sleep during those cold winter nights, you may need the heating on to avoid waking up cold. It'll be hard to sleep peacefully if you have an HVAC system making an excessive amount of noise. A functioning AC unit should be felt but not smelt or heard.


Poor Circulation


It's time for heating inspections if you can only feel warm air from your unit when standing nearby. A functioning unit is supposed to circulate heated or cooled air throughout the home. If air is concentrated in one room or a particular spot in a room, you know it's time for repairs or replacement.


High Bills


Have you begun to dread opening your energy bills? Even if you haven't been using more electrical appliances or your AC unit more than normal, your energy bills can increase if your HVAC system is no longer as efficient as it should be. Heating inspections can check for issues that are reducing such efficiency. It's also a time when your AC inspector can recommend whether to install a new unit such as those from the Energy Star brand or a mini-ductless unit.


Incorrect Temperatures


How does the temperature feel when you turn on your unit? For example, if your unit is set to a specific temperature, but it doesn't feel like the temperature it's set at, then it's time for
heating inspections. You want a reliable system that'll produce heat at the temperature it's set at, and not suddenly cool down even though you didn't touch it.


Having a healthy HVAC system helps keep your home safe and comfortable. All homeowners should understand the signs that come from having HVAC problems so it's clear when it's time to call a professional. Look out for leaks, circulation issues, and higher bills. With the right professionals on hand to do frequent heating inspections, you can have a quality unit that can work for years to come.
