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.

Q: Can you run an attic fan with the AC on?

• <div><p>Yes, you can run an attic fan with the AC on. In fact, you don&rsquo;t have a choice with a passive attic fan. Plus, when an attic fan draws out hot air from the attic, it helps regulate the temperature of your whole home, so your AC doesn't have to work as hard. </p></div>

Q: How can you avoid overworking your HVAC system?

• <div><p>Turn your system off when you're toasty or when you're out to prevent unnecessary wear. Using the timer on your thermostat so that it switches off when it reaches a certain temperature or turns on just before you get back from work is best. An annual maintenance contract can be helpful to ensure your system receives these important services at regular intervals.</p></div>

Q: Is an HVAC compressor covered under warranty?

• <div><p>Many HVAC manufacturers provide warranties that encompass the cost of a new compressor, with durations ranging from 5 to 10 years, depending on the brand. These warranties cover critical components such as the compressor, condenser, connecting tubing, evaporator, and refrigerant charge. Moreover, they often include the necessary labor for replacement or repairs. Keep in mind that premium-brand compressors may offer lifetime warranty options. It's essential to note that these warranties rarely cover labor costs.</p></div>

Q: What month should I start using my air conditioner?

• <div><p>This is a bit of a trick question. Even though the seasons arrive at the same time every year, the weather doesn&rsquo;t always behave according to the calendar. So, while it&rsquo;s fair to say that you can expect to turn on your AC starting in late May or early June, it all depends on the outside temperature and how cool you like to keep your home. </p></div>

"GAC services was able to come out for a same day trouble shooting appointment. Jim S arrived on time and was very courteous and professional. He was able to quickly identify the problem with the registers and dampers and able to get warm air flowing to the otherwise very cold areas of the house. In addition, Jim was able to recommend some additional services that would help me achieve the desired evenness of temperature such as an additional return and humidifier for the home. Great experienced master certified technician!"

"I appreciate the experience, expertise, knowledge and integrity of this business. The home I live in is very old and I am a renter with very little knowledge of HVAC services. Sean, the serviceman, explained clearly what the issue was with the furnace and even provided advice regarding CO detectors, that I should have more than one. I am very grateful for the service he provided and I definitely recommend his company."

Customers say: True professional

"I had the best experience with Hecomo Heating & Cooling. My house's AC/heating system stopped working all of the sudden and the temperatures at the time were 90 degrees and up. I was desperate looking into many different companies. Many of them, came over to my house and did estimates at ridiculously high prices. Luckily, I found Hecomo. They came to my house, did an estimate and were ready to install my AC/heating unit very quickly and at a good price. Also, the customer service was great. They were there for me throughout the whole process. They explained to me everything that I needed to know about the system and the features. Everything is very modern and updated. I am very happy I found Hecomo."

Yes, you can run an attic fan with the AC on. In fact, you don’t have a choice with a passive attic fan. Plus, when an attic fan draws out hot air from the attic, it helps regulate the temperature of your whole home, so your AC doesn't have to work as hard.

Many HVAC manufacturers provide warranties that encompass the cost of a new compressor, with durations ranging from 5 to 10 years, depending on the brand. These warranties cover critical components such as the compressor, condenser, connecting tubing, evaporator, and refrigerant charge. Moreover, they often include the necessary labor for replacement or repairs. Keep in mind that premium-brand compressors may offer lifetime warranty options. It's essential to note that these warranties rarely cover labor costs.

This is a bit of a trick question. Even though the seasons arrive at the same time every year, the weather doesn’t always behave according to the calendar. So, while it’s fair to say that you can expect to turn on your AC starting in late May or early June, it all depends on the outside temperature and how cool you like to keep your home.
