Helpful and polite answers all my questions will use them againPosted on Dan S. DentonTrustindex verifies that the original source of the review is Google. The thermostat was identified as being defective, and replaced. The new system was installed on Aug.26, a little over 3 months ago, and has now been repaired 3 times. I hope that the third time will prove to be the charm.Posted on Lisa DykesTrustindex verifies that the original source of the review is Google. Very pleased with Napps today. I called them at 1:00 and they were out within a couple of hours. Our stopped up drain was very stubborn, but they worked until everything was cleared. We felt their pricing was very reasonable, the technician was nice and polite and efficient. We will use them again and we give them 5 stars.Posted on Wendy AlbrightTrustindex verifies that the original source of the review is Google. 11/1/24 I have a maintenance agreement with Napps and my favorite tech, Zachary came this morning to check all of my HVAC units.

Honeywell generators are built for automatic, whole-home or whole-building backup power. When utility power fails, your system turns on within seconds — no extension cords, no scrambling, no guesswork.
Key benefits of Honeywell generators include:
For homeowners in Longview, where thunderstorms and extreme summer heat are common, a Honeywell standby generator provides year-round peace of mind.
Many customers contact us after experiencing a major outage. Maybe the AC shut off during a 100-degree afternoon. Maybe medical equipment lost power. Maybe a business had to close early.
A professionally installed Honeywell generator can power:
We help you determine whether you need full-home coverage or a customized essential-load system. Proper sizing is critical. An undersized generator leads to frustration. An oversized unit increases cost without added benefit. Our team calculates your real power needs to ensure balanced, reliable performance.
If you’re already protecting your home comfort systems, pairing backup power with our HVAC services ensures your heating and cooling stay operational during outages.
Generator installation requires careful planning, electrical integration, fuel connections, and strict code compliance. This isn’t a DIY project.
Our installation process includes:
We assess your electrical panel, fuel source, and property layout to determine ideal placement.
We calculate your electrical load to recommend the correct Honeywell generator model.
We handle local Longview and Northeast Texas permitting requirements to ensure your system meets all safety standards.
Our licensed technicians integrate the generator with your home or commercial electrical system safely and professionally.
Before we leave, we fully test your system and walk you through how it works.
Our installation approach reflects decades of experience serving the Longview community with dependable mechanical systems.
A standby generator must be maintained to remain dependable. Like your HVAC system, it requires routine inspections and servicing.
Regular maintenance typically includes:
If your generator is failing to start, showing warning lights, making unusual noises, or not transferring power properly, immediate service is important. Quick repairs prevent costly failures when you need power most.
For businesses in Longview, power loss means lost revenue. Offices, restaurants, healthcare facilities, warehouses, and industrial buildings rely on consistent power to operate safely and efficiently.
We design and install commercial Honeywell generator systems tailored to your facility’s operational needs. Our commercial services team understands how to minimize downtime and ensure compliance with safety standards across Northeast Texas.
If you’ve ever thought:
“I can’t go through another outage like that.”
“I’m worried about losing AC during summer.”
“My business can’t shut down unexpectedly.”
“I need backup power for medical equipment.”
Then it may be time to consider a Honeywell standby generator.
