If your HVAC settings appear to be correct, why in the world is your air conditioner blowing hot air? The most basic function of an A/C is to deliver cool comfort, so if you’re feeling a warm blast from the vents instead, something’s definitely amiss. It may be a simple matter you can resolve yourself or it may require diagnosis by a qualified technician. Here are some scenarios that might be at fault if your HVAC settings are blowing hot air instead of cool.
Air conditioner sizing is a critically-important consideration when you're planning to purchase new cooling equipment. According to the U.S. Department of Energy (DOE), an A/C's size needs to match the space it's going to cool. An undersized A/C will run for extended periods, use a lot of energy, but won't cool your home's interior sufficiently for comfort. An oversized air conditioner will only run for short cycles, so it won't dehumidify effectively or cool your living space efficiently.
If your sunroom is simply too hot to occupy during the summer, why not consider different sunroom HVAC solutions to make it cooler. There are practical ways to bring air conditioning to this room that are effective and affordable.
Giving some thought and preparation for guest house comfort before you have summer visitors will ensure that they’ll find your home as comfortable and inviting as you do. People tend to acclimatize to different temperatures and what’s comfortable for you may not be for someone else. Should the guest space be separate, you’ll find innovative and versatile ways to keep it comfortable.
A portable A/C makes home cooling mobile. These units are mounted on wheels for transport and sized to fit through interior doors in residences so they may be easily re-positioned anywhere in the house. Most models can serve as both temporary spot coolers bringing quick comfort to any space in the house, or adapt to a more stationary role in a dedicated room, substituting for a conventional window air conditioner.
It won't be long before the heat and humidity arrive, and you'll be turning on your air conditioner to keep your home comfortably cool. Before you reboot the A/C and start using it consistently, be sure to take these steps:
Normally, a properly functioning air conditioner makes occasional pops, hisses, rattles, and a quiet hum that shouldn't be a cause for concern. However, if you notice a loud humming or buzzing noise, your unit is probably malfunctioning. Several issues can cause a humming air conditioner. Let's take a closer look at them along with their solutions.
The thermostat is the HVAC system's command center. If your home has heating and cooling problems, a malfunctioning thermostat is a likely culprit. Fortunately, most thermostat problems aren't major, so you'll probably just need to adjust your existing one rather than getting a new one. Here are the possible reasons behind your device getting off schedule, along with the steps you should take before calling a professional.
There seem to be apps for everything these days. If you can think of a function, there's probably an app for it. Both Apple and Google's Play Store each offer more than 1.5 million apps. That's why it's not surprising that there are even apps that apply to your home systems, including your HVAC. Let's have a look at some of the apps you might want to download to use for your air conditioner and heating.
Air conditioners, like every other piece of equipment in your home, have their span of days and then it's time to replace them. Fortunately, they do last a long time — on average, 10 to 15 years. In fact, the age of your A/C system may be one key indicator that it's time for to replace it.
A defective A/C condensate drain is a common cause of water damage inside homes. Condensate is simply water vapor condensed into liquid by contact with the cold evaporator coil in the A/C’s indoor air handler. Whenever your air conditioner is running it’s producing condensate — as many as 20 gallons on a humid day. As long as everything’s working right, the condensate is collected and diverted away down a line into your household drain system. If something goes wrong, however, gallons of water may end up spilled into your home — often before you even realize there’s a problem.
Shopping for a new central air conditioning system for your home is no picnic, but you can make the task a lot simpler — and easier on your pocketbook in the long run — if you take advantage of air conditioner ratings that show how efficiently an A/C converts electricity into cooling.
Buying a new air conditioner can be a daunting task for the homeowner, but if your A/C is getting on in years, losing efficiency, racking up repair bills, or simply not performing as well as you'd like it to, it can be a major improvement. Follow these tips to make sure that your new A/C will serve you well:
When's the last time you scheduled a preventive maintenance tune-up for your home's central air conditioning system? If you can't remember, or it's been more than a year, you should schedule an A/C maintenance visit as soon as possible. Your system has likely lost efficiency and may be under-performing, while small problems that haven't been addressed may be developing into larger ones. Most HVAC experts recommend annual service on your central A/C and semi-annual service for heat pumps.
Your central air conditioner shouldn't be tripping the circuit breaker in your home. If it does this just one time, it's not necessarily a sign of problems. It's when the A/C is tripping the circuit breaker a second and third time that you need to address the issue. It probably reflects an underlying problem with your cooling system. First try some do-it-yourself troubleshooting, then if that doesn't work, call in an HVAC professional.
One thing that can be confusing to homeowners is the difference between a central air conditioner and heat pump. They look the same, and they both cool the home in the summer. So what's the difference? Following is an explanation of how a heat pump differs from an A/C.
If you're new to the task of buying a home, you'll want to acquire at least a superficial knowledge of residential heating and cooling systems. We'll start with heating, then move to air conditioning to help prepare you for choosing a new HVAC system.
