"I hired this crew to replace some old ductwork & add a couple vents. Wish I did it sooner. The estimator actually listened to what was going on, crawled the attic/basement, took pics, and explained what was leaking vs. undersized. The quote was clear, not the cheapest, not the highest, & they stuck to it. No weird upsells. Install day, they showed up on time, laid down drop cloths, and got right to it. They swapped a few crushed flex runs for rigid metal, sealed every joint with mastic (not just tape), insulated the attic runs, and added a proper return. They also put in balancing dampers so each room could be tweaked. Little touches too: they fixed a wobbly register I forgot to mention and cleaned up as they went. Place looked better when they left. The difference is real. Airflow is stronger but quieter, rooms are finally the same temp, and the system isn?t working as hard. Even the dust in the house seems better. They walked me through everything!"

"Fantastic. Jonathan knows what he’s doing, very precise with measurements, and has a wide range of abilities. So friendly and personable. He helped transform our new build house into a finished home. He is able to install many things, curtain rods, ceiling shower rods, heavy mirrors, heavy art work, and now is tackling adding wire rack shelves in our closets. Next up some Ikea cabinets in our laundry, and painting our garage. His prices are up front and very reasonable. He is licensed and insured. We feel he is quite a gem to have found! Would not hesitate to hire him again and again. He is very positive, eager to work and does excellent work."

When you need AC heating or plumbing services, look no further than Horizon Services. For nearly 30 years, we’ve been the trusted name in plumbing heating, and air conditioning, offering an unmatched level of service at reasonable rates.

"Less than 5 years ago, I spent in excess of $10,000 to have a new unit installed with a 10 year warranty. I should have seen the red flags from the very beginning. The sales representative told us additional vents would be installed and when the installation crew showed up, that did not happen. Fast forward to the present and I am now on my 4th phone call for an appointment this season, 3 days so far of not being able to work as I waited for a technician to come diagnose the problem. The 3rd. tech came last night and indicated that the work the other tech did was not for the root of the problem. (I was told in front of witnesses that the work needed to be done, was not covered under warranty, would cost me $367 and would fix my issues)In fact, the 3rd tech only made the issue worse by leaving our attic return unscrewed and overfilling our unit with Freon that the 4th tech had to remove from our system. Upon leaving last night I was told that everything was corrected. Today - my home is slowly creeping up in temperature (presently 80 degrees inside, while set to 72). The company keeps trying to sell me a "maintenance plan" and I keep reiterating to EVERY one who pushes it that we have been getting tune ups/cleanings elsewhere and will only use them for warranty issues since we have had NOTHING but problems with them."

"Worst service I’ve ever have experienced. They wanted to sell me the product, never told me that there was an early termination fee and another penalty for an initial offer they gave me. Had double charges every month, once for the oil they provided (which they never told me they were going to provide before coming. They just came without my knowledge and then I find a high amount bill) and another for an “automatic payment” for 500 that they never could explain. The didn’t even fix this issue and it kept happening every month even after I cancelled the service. Then having to call them is a hastié for the refund of the 500. Stay away of this company"

FAQs for thermostat installation and replacement projects in Wallingford, PA

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.
