"After so many negative experiences with people claiming to be "professionals" I contacted Mr Whitingham at Smart Dova's Home Renovation to install several blinds.  After my request for a quote he responded with a return call within minutes.  He came right over. We agreed on a price. He returned when promised and completed the job.  I was very happy with the outcome, so when I wanted to get estimates for a very large renovation, I again called Smart Dova. He gave me a detailed estimate, and a start date. When he began the demolition, he brought a large crew. For every phase: demolition, reframing, insulation installation, the necessary wiring, installation of fixtures, drywall, painting, and refinishing the fireplace and the hardwood floors, he had an appropriate crew for the work.  He discussed each phase with me.

"We hired Juan to installed new subway backsplash and remove old peel & stick backsplash from kitchen. Juan mentioned he was a little busy but will be able to take the job on and complete it on a timely manner. Juan installed the backsplash on a Friday evening after 4pm and worked until about 10pm to get the backsplash completed. Juan returned on Sunday after noon to complete the tile work after allowing mortar to dry. However, the issue was Juan did not wipe up access mortal and/or cleaned off the tile. Juan left drops of mortal on our floors (which we had just cleaned from Stanley Steamer). Juan left a few pieces opened-no tile is in those cracks. Juan left the tile backsplash with streaks from the sponge. And Juan did not apply border of caulking to the edges. Juan left tile with streaks and clumps of mortal around our cabinets, on tile and on the wall. After discussing these concerns with Juan he mentioned I was criticizing his work and his integrity. Juan mentioned he has not had a dissatisfied customer who have complained about his work. I mentioned to Juan my OCD kicked in and when we hire someone to do the work the expectation is to complete the work to customers satisfaction and clean up after you have completed your task for the day! Juan mentioned he will return to ensure we are satisfied and complete the work and neither less to say I received a text from Juan stating he will return $100 off the bill that was paid to us and he does not want to work for us! Bad customer services and not acceptable for any customer Very Disappointed"

Heating and Air Conditioning questions, answered by experts

The DOE is phasing out AC units with SEER ratings that fall below 14 or 15. The exact minimum rating depends on your region. In the northern United States, new ACs must have a minimum SEER rating of 14, though you can still buy and install older systems as long as they were compliant when they were manufactured. In the southern and southwestern United States, you cannot buy or install older air conditioners with lower SEER ratings. The minimum rating is between 14.5 and 15, depending on the power of the unit.

It is normal for the attic to be hotter than the rest of the house in the summer, but only by about 10 or 20 degrees. Attics that aren’t properly insulated or ventilated can reach temperatures of 130 degrees or more which can cause damage to the home’s structure, including the roof, wood framing, and HVAC system.

Look up your model number online to find additional information. Usually, you can just take a look at the old filter and find the brand name and dimensions to order a new one. When replacing the filter, always check that it’s pointed the right way to match the direction of your airflow. Many filters have arrows on them to help with this step.

HVAC replacement doesn't always include ductwork replacement. It depends on the condition of the existing ductwork. You can reuse your ducts if they are in good shape, adequately sized, and meet current standards. However, if the ducts are damaged, poorly designed, or not appropriately sized for the new system, they may need to be replaced or upgraded. HVAC contractors will assess the condition of the ductwork during the replacement process and recommend any necessary modifications or replacements to ensure the new HVAC system operates efficiently and distributes air effectively throughout your home.

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.
