"We had our hot water heater replaced and I'm impressed! They didn't charge me extra for calling after 5pm. I was scared of being charged for an emergency call. They texted info of the technician coming to my house. As a woman, I appreciate knowing WHO is coming to my home. I don't want just anybody coming with my child in the house. This is a great family company. They arrived as promised and promptly stopped the old water heater from flooding my garage. My new water heater works great! They fixed my pressure regulator and I can enjoy my house again!"

"He gave us an estimate then went to Home Depot to get supplies, for which we paid. He spread a drop cloth on entry pavement. He removed old pain pieces on frame, cut the screen he bought in half and screwed them to the bottom of each door. He then spray painted the doors white. The doors needed more paint, so he went to Home Depot again and bought additional cans of paint (12 in total). I got sick from the paint smell, so my sister took over. When he finished she paid him. When I was able to inspect the job, I saw a hole in one doors screen and long screws sticking out 3/4" on both screens. I sent hime a text message to his phone, but got no response, so I phoned him to discuss the matter. He said his drill slipped punching to hole in the screen and that's the only screws he had. He said the screen is too expensive to replace and the screws are it. He said he"

Heating and Air Conditioning questions, answered by experts

Installing a new AC unit costs $5,850 on average, but costs vary by the make and model, unit size, and unit type. Portable and window AC units cost between $90 and $550, which is significantly less than central or ductless AC systems. You’ll also have to pay for labor.

Freon will go in the refrigerant lines near the back of your AC unit. Look for small ports with caps on a thin copper line—the Freon goes into those ports. You are best off hiring a licensed HVAC professional who can complete the job safely and correctly.

The best way to compare HVAC quotes is getting a few detailed quotes from local companies with good reputations. Then, go over the quotes line by line. Protect yourself by insisting on in-person estimates that include equipment manufacturer names, model numbers, SEER ratings, amounts and numbers of materials, details of warranties on equipment and labor, and other specifics. 

Knowing the exact equipment and materials is the only way that you can fairly compare quotes. Quotes that are much lower than others can be a sign that the company isn’t providing the best quality service or materials.

Turn your system off when you're toasty or when you're out to prevent unnecessary wear. Using the timer on your thermostat so that it switches off when it reaches a certain temperature or turns on just before you get back from work is best. An annual maintenance contract can be helpful to ensure your system receives these important services at regular intervals.

You will only need to refill your AC with refrigerant if it has a leak. Otherwise, a modern, well-maintained AC will most likely never need a recharge. You may notice a leak in an older system if your bills are higher, you hear a hissing sound, or if the air is blowing out hot.
