Q: Do all portable AC units need to be drained?

• <div><p>While all portable AC units will collect moisture as part of their cooling and dehumidifying process, whether and how often you need to drain them depends on what kind of unit you have and the natural humidity levels where you live. For example, if you live in a very dry area and have a self-evaporating unit, you may not need to drain your portable AC very often at all. Some units may automatically drain collected moisture out the window through their exhaust vent.</p></div>

Q: What’s the difference between a home surge protector and an HVAC surge protector?

• <div><p>The difference between a home surge protector and an HVAC surge protector is that an HVAC surge protector is designed to protect the components inside your HVAC unit while a home surge protector is installed near appliances and meant to protect your entire home. There are three tiers of whole-house surge protectors, and they are more expensive to install than HVAC surge protectors.</p></div>

Q: Will upgrading my HVAC system add value to my home?

• <div><p>A new HVAC system can add 5% to 7% to your home&rsquo;s value, especially if you upgrade the entire system, including ductwork and insulation. In total, these upgrades could bring around a 30% return on investment (ROI). Add a smart home thermostat, and your home&rsquo;s value could increase because the heating and cooling systems are more modern, efficient, and convenient. </p></div>

Q: How many HVAC quotes should I get?

• <div><p>Most experts recommend getting three to five HVAC quotes from licensed, insured, reputable local heating and cooling companies. Getting multiple detailed HVAC quotes (but not too many) lets you compare the equipment, services, and prices of several contractors without being overwhelmed by options. It can also let you see if one contractor&rsquo;s prices are much higher or lower than the others and give you a chance to ask for clarification. That way, you can weed out any contractors who aren&rsquo;t providing quality services or materials and find the company that best meets your budget, quality requirements, and long-term goals. </p></div>

Q: Should I turn off my AC if it’s blowing hot air?

• <div><p>Yes, it&rsquo;s best to turn off an AC unit that&rsquo;s blowing hot air to prevent system damage and avoid expensive energy bills. If you let the AC continue running, it will put more strain on the condenser coil and compressor. Plus, if the AC is blowing hot air because of a refrigerant leak, it can also lead to a frozen evaporator coil.</p></div>
