"They did have a good price, but their customer service is horrible. They have no respect for your time when scheduling appointments. I sat at home for hours waiting for an Inspector, when the Inspector told me I should have been provided their name and phone number to schedule with a short window. And, unlike what they advertise on their website, they are not a 24/7 business. :-("

I started "I'll Handle It" to address what I recognized as a need that homeowners have for competent, knowledgeable and courteous home improvement service professionals to help them with all manner of projects large and small. Founded in San Diego, "I'll Handle It" is a home grown business that prides itself in its responsiveness to its customers needs. At "I'll Handle It" "Professional Service You Can Rely on" is our mantra, and we can prove it.

"Dave was great! The best communication and transparency I've seen in a long time. Dave explained what he needed to do to install the dryer vent and got right to work...NO wasted time. He installed the vent and made sure it was working properly. The vent looks great! Dave is knowledgable, professional, and a nice person. He also stayed in touch, letting me know how soon he would arrive and when he was on his way. I really appreciated that. We will definitely call him the next time we need a handyman."

FAQs for thermostat installation and replacement projects in San Diego, CA

Smart thermostats may be worth it for many homeowners. They come with various features, including voice control and smartphone apps. Vacation mode can help lower energy usage when you’re out of town for an extended period. Alert warnings let you know about major spikes or drops in temperature. Smartphone apps can track energy usage, and smart thermostats can learn your routine over time to adjust your temperature and reduce wasted energy consumption automatically.

You typically do not need more than one smart thermostat. While it’s common to see multiple mechanical thermostats throughout a large home, multiple smart thermostats may try to override each other. This can lead to problems with the HVAC system. Ensure the unit you buy has the option for dual- or multi-zoned systems to avoid compatibility issues.

Installing a programmable or smart thermostat may save you $180 per year in utility costs. A big part of this comes from a smart thermostat’s ability to learn and adapt to your regular routines. With smartphone apps or web-based interfaces, you also have the option to control your thermostat when you’re not home.
