Rooftop Unit Repair in Baltimore, Lutherville-Timonium, Ellicott City, MD and Surrounding Areas
So your rooftop unit broke down. That’s not something you want to wake up to. But they are prone to do that because of their location and the fact that they are so open to the outdoor elements. In fact, rooftop units see more wear and tear than any other appliances. Therefore, repairing them is a must from time to time. With this idea in mind, we have put together a small but comprehensive guide for people who own a rooftop unit, just in case something goes amiss. Here’s everything you need to know and always wanted to ask a professional about a rooftop unit repair.
Indicators that Your Rooftop Unit Needs to Be Repaired
The first thing you need to think about is that since it spends all its life on your roof directly exposed all the weather elements such as snow, ice, rain, and powerful sunlight, your rooftop unit will inadvertently break down now and then. But, apart from it stopping to work altogether, how can you tell when that is happening?
1. If your electric bills go up all of a sudden
Should you experience this for the first time during the hot season even though you’ve had your rooftop unit for quite a while, it may be a sign that something is wrong with it. There may be a number of causes for that which include dirty air filters, a damaged compressor or the refrigerant leaking.
2. If your thermostat is not accurate
You set your thermostat to a certain temperature and then someone changes it. But that’s not the problem we’re talking about. If you start noticing that your building is actually not as warm or as cool as the temperature your thermostat is showing, then the unit on the roof may need to be repaired.
3. The temperature is not constant throughout the area servicing
This effectively means that some of your rooms may be hotter or colder than others even though you did not set these particular temperatures yourself. If certain areas of your building are now heating up or cooling down a lot faster than other areas, there may be a problem with the airflow or with the unit itself.
4. You can smell funny odors
This is one of the easiest ways in which you can tell that something is wrong and you need to go for a rooftop unit repair. HVAC related odors are also called ‘the dirty sock syndrome’ because that’s exactly what the air coming out of your vents smells like.
If you start smelling this, do not ignore it! It can lead to serious consequences that can affect your health. Call an HVAC professional that will be able to correctly assess the situation and fix your rooftop unit.
The Most Common Rooftop Unit Issues
Now that you are familiar with the signs that tell you something is wrong with your rooftop unit, let’s take a look at the most common issues that happen to this HVAC system. These are issues reported by users to professionals. If you have any reason to believe that one of these situations applies to you as well, please don’t hesitate to give SuperTech a call!
1. The HVAC economizer might have failed
Your HVAC’s economizer is what reduces cooling costs overall. It allows the outdoor cool air to come into your house so that it can improve the system’s efficiency, reduce the levels of CO2 inside, and improves the fresh air. It has either a temperature or an enthalpy sensor that helps it work in a proper manner. Both detect temperature and humidity.
When the temperature outside has reached a cool degree, the dampeners on your HVAC will open and let some air in for the purposes we’ve already mentioned. If the sensors, the economizer or the dampener fail, than the whole unit will use between 14 and 40 percent more energy to keep your house cool. You will also need to get them fixed as soon as possible.
2. Unbalanced refrigerant levels
Every rooftop unit needs refrigerant so that it can manage the heat transfer. However, if the levels happen to be either too high or too low then your system will start working abnormally, the pressure will be off.
In fact, some people even report an increase in their bills when it comes to cooling their houses which can be up to 11 percent. If that happens, call in a specialist to fix your rooftop unit and get things back on track.
An HVAC technician is the only one who can fix your rooftop unit. He is also the only one who should be in charge of maintenance on a regular basis as your unit is a very complicated mechanism located in a dangerous place. Please remember that maintenance is just as important. During the maintenance checkup, a professional might spot problems with your unit that you weren’t even aware of and that can get fixed before they develop into more serious issues.
