"Horizon Services Warranty Entrapment New to Delaware, but struggling with a HVAC warranty issue with Horizon. Advice Please. I have been waiting 3 months for an Appointment to get my annual HVAC system serviced by the Horizon team. Starting this process in June, I was told that September 12th was now an Option after 10 min on hold. I did not accept this as this was another month out and I was not available. I have made no less than 5 attempts to get a service appt on my HVAC and each time, since the "10 Year Warranty" maintenance team is 1/10 the size of the fleet driving around, I was told I would be put on a waiting list to be called back. Nothing! No one ever called me. I keep calling them. Horrible! My frustration is a legal one: My system warranty was several thousand dollars on top of the new units and installation. However If i dont get a $149/year Annual Service I void this; if someone else services the units-I void this. I want a way out: 1) Horizon to reimburse or pay another HVAC company of my choosing to perform this service, and keep my warranty in tack in writing. 2) How about a business model for warranty holders: Schedule me like a Dentist....11-12 months year from my last appointment (provided not winter so my AC can be checked), they send me an appointment reminder. This is a big hassle, anyone else have this issue? PS> During my call 8/16 at around 10:30am, i told the representative this was it, if no call back, I would hit social media (Facebook, Linkedin, Nextdoor, BBB). The power of sharing, the power of community. Northern Delaware stay tuned, I will be asking Next Door for Recommendations and a Legal way to keep my warranty just in case and go elsewhere. 12m ago · 55 neighborhoods in General"

McCrea is a family owned business that has served our area since 1936. Financing and rebates are available on Trane systems installed by McCrea. Resistrictions apply and these are limited time offers call for details. "Its hard to stop a Trane"

"I had an absolutely terrible experience with McRae Air Conditioning and Heating. I purchased a home equipped with their HVAC system, and within just five months, the heat stopped working—right in the middle of winter during a snowstorm. My home was freezing at 50°F, so I called for service, which should have been covered under warranty. I scheduled an appointment, and the technician, after being several hours late, went to the wrong address, left a sticker on someone else’s door, and left without even trying to contact me. When I called back, the customer service rep was rude, dismissive, and completely unhelpful. He initially told me the technician was on the way and just 12 miles away—but after another hour of waiting, I called again only to be told that the technician had already “been to my house 2 hours ago” (the wrong one) and left a note. If the rep actually wanted to help, he would have told me this during my first call instead of wasting my time and leaving me sitting in the cold. Not once did the technician call me to confirm the address or check in after knocking on the wrong door. When I expressed my frustration, the rep rudely dismissed my concerns, saying, “Well, I had nothing to do with that,” and then interrupted me with, “Do you still want to rebook or not?” as if I had to stop talking or risk not getting another appointment. This was an emergency call in the middle of winter, and McRae handled it in the most unprofessional, careless, and disappointing way possible. If you’re considering using them for HVAC service, do yourself a favor and go with another company. I’ll update this review after the (hopefully successful) service call and speaking to the manager who was not there at 4 pm on a Wednesday."

"Talked to a lot of companies. Mike was about as dte & real as you get. Immediately got good vibes. He sent his 2 son's out to check out my AC unit outside. I'd gotten varying opinions & estimates. Tbh, I became weary, but I figured Mike wasn't feeding me anything but what was real. His boys showed on time, extremely polite, well mannered, knowledgeable & professional. They went right to work. Found the problem without trying to sell me a bunch of extra stuff or pad the price for something it didn't need. Without hesitation, I said do it! I have to admit for 2 very young guys, they knew what they were doing. When they were done fixing my system was cranking it out & putting like a kitten. I was afraid out what my bill would be. Couldn't believe how fair & reasonable it was. No extra fees, taxes, add ons etc...EXTREMELY IMPRESSED...I definitely found a HVAC + Co on the Eastern Shore I trust and highly recommend them.

FAQs for thermostat installation and replacement projects in Lewes, DE

It's often worth replacing your old thermostat with a newer model that can enhance your home's comfort and energy efficiency. Upgrading to a programmable or smart thermostat can save you up to $200 per year on energy bills. Plus, smart thermostats offer convenient features like remote control and learning capabilities, making your home more comfortable and easier to manage.

Signs of a bad thermostat include your HVAC system not turning on when it's supposed to or failing to reach the desired temperature. If the thermostat's display is blank or not functioning properly, it could be malfunctioning. Another indicator is the HVAC system running continuously without shutting off or cycling on and off too frequently. You might also notice uneven temperatures throughout your home, with some rooms being too warm or too cold. These issues suggest that the thermostat is failing and may need repair or replacement to ensure your HVAC system operates efficiently.

A thermostat should last between 10 to 20 years, depending on its quality and how well it's maintained. Over time, dust, wiring issues, and general wear can affect its performance. Even if a thermostat is still functioning after 10 years, you might choose to replace it to take advantage of newer energy-saving technologies and smart home integrations. Upgrading to a modern thermostat can improve efficiency, offer more control over your home's climate, and potentially lower energy bills.

The number of thermostats you need depends on your home's size, layout, and heating and cooling zones. In a standard single-zone HVAC system, one thermostat controls the temperature for the entire home. However, larger homes or those with multiple floors might benefit from multiple thermostats linked to a multi-zone HVAC system. This setup can offer better comfort and energy efficiency: It lets you customize the temperature in different areas, so you're only heating or cooling the spaces you're using.

Replacing a thermostat typically takes a professional technician about one to two hours to complete. If you're swapping out an existing thermostat for a similar model with compatible wiring, the process can be done in less than an hour. However, installing a new thermostat that requires additional wiring, such as a smart thermostat, or moving the thermostat to a new location can extend the time to two hours or more. Complex installations may also involve cutting into drywall or integrating with other home systems, which can add to the duration.

There are a few things that can cause your home thermostat to fail. The most simple one is age and cleanliness. Dirt, grease, dust, and other small particles can clog sensors and cause malfunctions in readings. You may also have a failing power supply and loose connections, and the simplest cause is that it isn't installed in the right place in your home so it can't properly sense air temperature. Repairing a thermostat costs around $210.
