He installed a new screen door, replaced my tub stem and faucet, repaired my subfloor in the kitchen and installed brand new LVP flooring to replace old and water damaged flooring. He also mounted a television for me, and did some drywall repairs as well. I would recommend this business to anyone looking for quality and dependable work!"

"Mr. Craig was excellent to work with. Our project was to make our condominium home's handicap and wheelchair accessible. Space was not available to go full ADA specifications, and plans construction plans were not available. Mr. Craig worked and us in thinking 'outside the box' of the typical/usual. One of our family members has a progressive weakness disability, and the solution will provide the capability of everything from walk-in to wheelchair with 'class'. Floors are slate tile, shower of cultured marble, fold-down teak seat, standard and hand-held shower heads with ability to alter between the 2, glass doors, coordinated grab bars and more, built-in closet shelves, etc. THANK YOU for making it so that we can remain in our home long term!"

Heating and Air Conditioning questions, answered by experts

One of the first signs of mold in an air conditioner is a musty smell. You're likely to notice the smell when the unit runs, from the air coming out of the vents or the unit itself. You may also be able to see mold growing on the unit, such as near the condenser coils or by the fan. In some cases, there may be visible mold by the vents.

To find a reputable HVAC company, start by researching providers in your area. Look for companies with mostly positive online reviews and check the Better Business Bureau’s website for customer complaints. Next, verify their credentials. Rule out any companies that aren’t licensed, as this is a requirement in some states and municipalities, and confirm they are insured. Once you have a shortlist, contact each professional to ask key questions: How many years of experience do you have? Do you hold any third-party certifications? Do you have experience working on my specific type of HVAC system or brand? Can you provide references? What is your per-hour pricing? Do you offer maintenance contracts for ongoing savings? Do you provide a warranty for your work?

Yes, having mismatched evaporator and condenser coils in your AC system can lead to serious issues. For instance, it can result in higher monthly energy costs as the system runs longer to compensate for the mismatch. This mismatch can also put extra stress on the system, compromising its efficiency and longevity. 

Along with that, mismatched coils can lead to higher temperatures and humidity levels in the home. What’s more, using coils of different sizes may violate the manufacturer's warranty, as they are designed to work synergistically, and any mismatch could lead to repairs and system failure.

Window ACs use 500 to 1,400 watts per hour of electricity, while mini-splits use 500 to 700 watts per hour. However, if you need to cool multiple zones in your house, your mini-split can use as much as 2,000 watts per hour. How often you run your system will impact how much electricity you use (and how much you pay per month).

It depends on the size of the space you’re cooling down. If you’re looking for the most affordable way to cool an entire house over a long period of time, then central air will be more cost-effective. But when it comes to cooling down a couple of rooms or one floor, a window unit may be the cheaper option, with both a lower cost to install and less energy used to run.
