"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."

"We had to replace our furnace, and contacted Javier Cano as listed on Angie's List. He was very professional, explaining every detail and type of furnace to install. He is very easy to work with, as is his son. They did a wonderful job of installing the new furnace, and we are very happy. I would highly recommend Cano Heating & Air Conditioning."

"I had called another plumber who was a jerk and only gave me a recount of problems. When I called these guys they were there in a hour, and Robert Ibarra did a great job with a smile. He looked at my old Victorian house and found solutions to our problems, and then fixed the kitchen sink, and installed our tiny bathroom sink. We will be calling them in the future!"

"HVAC Experts was one of the best experiences I have had with a contractor and home improvement! I was able to get a quote based on some basic information I gave to Alex which was to be verified onsite if I moved forward. I really did like that since I am a very busy person. The price was very competitive but as we all know that is only one component, its all about the quality of the product and installation. I was able to schedule the installation for a day and time that worked for me and on the day of installation my doorbell rang promptly at 8am. I did notice them parked outside early but I did appreciate them waiting to start exactly as promised. The initial crew were very nice and got to work right away then the company labeled van showed up with my new unit. Alex eventually showed up and did a walk through, I really appreciated him taking off his shoes which shows respect and making sure I was comfortable with the process. He also was very patient with the numerous questions I had and I also did a last minute upgrade to a Nest thermostat which he was able to run out and grab for me with no problem! Glad I did that we love the technology is brings. The removal of the old unit and the install of the new unit with this 4 man crew only took 3 hours and at the end the crew completely cleaned the area and Alex did a final walkthrough making sure I understood how to use the new HVAC unit and thermostat. He also tested the heat and cold and took temperature checks to make sure the output was as expected. We settled on the bill and I got an immediate receipt via email with the details. Top to bottom was very impressed with HVAC Experts a newer company but you can tell they have many years of industry experience! I now have a brand new AC unit and it’s working great!!!"

"My home had a very old AC unit that gave out on us this past summer. It has been very difficult for our family to find a dependable and reasonable company to come out to our home. I called ZRO and spoke with Josue on a Monday and was able to come out that same week with his technicians, they gave me a good deal and was very communicative through the entire install. Thank you!"

Nest Installation FAQs, answered by experts

It is very difficult to remove a colony entirely without using some kind of insecticide. However, some treatments are safer than others. Diatomaceous earth is a non-toxic powder application that creates barriers that insects can’t pass through. Some pest control companies offer liquid nitrogen treatments to freeze out termites without using pesticides. Some chemical treatments are safer to use around plants, water, and wildlife than others. Bait stations are generally less damaging to the environment than sprayed termiticides.

Fleas are master hiders, so they’re always looking for safe spots. In addition to living directly on your pets, they’re likely to hide in bedding materials, not unlike the infamous bed bugs. They also like carpet and thick grass, for similar reasons. They’re more likely to hang around dirt and debris in general, which is why it’s important to keep the home clean. 

Groundhogs are definitely cute, but it’s usually not a good idea to have them living in your yard. Not only can groundhogs tear up your grass and create unsightly holes and burrows, but they can also carry infectious diseases that are dangerous to humans.

Cockroaches, ants, flies, bed bugs, and termites are common in business environments.

Identifying the specific animal running on your roof at night can be challenging without direct observation. Common nocturnal roof visitors include raccoons, squirrels, opossums, and rats. Raccoons are bigger and can create heavy thumping sounds. Squirrels are agile and may produce rapid scurrying noises. Opossums tend to move stealthily with less noise. Rats can make scratching or gnawing sounds. To determine the culprit, look for signs like footprints, droppings, or damaged areas near the roof. For accurate identification, consult a pest control professional or set up wildlife cameras near potential entry points.
