"From the very beginning, Lonnie in sales provided me with a first class presentation and quote. The installation was scheduled and Steve, Dalton and Bob were on time and the job was completed in a timely fashion. The work was performed in a professional manner and they took the time to answer any questions i had. I might recommend Wade Heating and Cooling for all your HVAC needs"

"We hired Bactronix to clean the HVAC ducts in our house. Technicians Masson and Shawn arrived on time, did their work unobstrusively and efficiently, and answered all my questions politely and fully. They sent over before and after pictures of the ductwork by e-mail afterwards. Their work has made a positive difference to the air quality in the house, and we appreciate their services."

A cabinet had to be special ordered for the laundry room to cover some exposed pipes.  I requested additional cabinets along the wall which were of standard size.  Kevin worked on the project.  I showed him cabinets online that I liked.  He measured everything, gave suggestions on how to get around the pipe.  He went to Lowes and looked for cabinets that met my  requirements.  The standard size cabinets were in stock and he ordered another cabinet with sizing required to cover the pipe area.  When the ordered cabinet arrived, he obtained it from Lowes and cut out the back in

specific areas  to avoid the pipe area yet provide stability to the cabinet and leave the base shelf for storage.  He installed all three cabinets.  They look great!  Kevin has done a couple of other jobs for me and I have been extremely satisfied.  He is very professional and personable.  I will definitely use Handyman Matters again and would recommend them to anyone.

Heating and Air Conditioning questions, answered by experts

No. Evaporator coils are designed to work with specific refrigerant types, and they are rated by what kinds of refrigerant they use. It’s indicated with an “R” code. It’s important to match your evaporator coil and refrigerant or your system will not work properly. An AC technician can tell you what type of refrigerant your system needs and what evaporator coils will work with it.

The general rule of thumb for figuring out how much AC tonnage you need in your home is that for every 500 to 600 square feet of space you need to cool, you’ll need one ton of AC cooling power. So, a 1,000-square-foot home will need 2 tons of AC power. 

When deciding whether to repair or replace your air conditioner, several factors should be considered. It is generally worth repairing the unit if it's less than 10 years old, the warranty is still active, and you're dealing with a one-off issue. Most central AC units last about 15 years, while window units last 8 to 10 years. If your unit is approaching or has surpassed the 10-year mark and requires frequent or costly repairs (e.g., over $5,000), replacement is often the more sensible long-term investment. For older, inefficient, or out-of-warranty units experiencing multiple problems, replacing it is typically the better choice.

If the air coming from your AC unit is cool but never quite cold, there are a few reasons this might be happening. For starters, it could signal that your refrigerant levels are low. If there are no other indications of this particular issue, like hissing noises or frozen refrigerant lines, anything from dirty filters to damaged condenser or evaporator coils could be responsible for the problem.

A window AC unit is not completely silent. You’ll hear the sound of air blowing, and if you put your ear right up next to the unit, you may hear a slight hiss or gurgle as the refrigerant flows through the system. That said, if your system is making a running water sound, a loud banging sound, a grinding sound, or physically vibrating, you may be facing an issue or malfunction with your AC unit.
