"Trent did a fantastic job remodeling our bathroom, exhibiting precision workmanship with having to ensure the walls were square and plumb, as well as leveling the uneven basement floor, and putting in a cool curved shower door. He put marble tile in the shower, making sure each tile was perfectly aligned with the others to get a mirror affect from a distance. He then graciously handled a curveball from the customer (that’s me!) when I decided to change the color of the grout AFTER one wall was done. He obliged and re-grouted to my satisfaction, with no harm done to the beautiful marble tiles!"

Small jobs welcome

Hi! I’m Matt and I’ve been plumbing for 2 years! I’ve worked with and installed many different systems, but I specialize in water heater install and service, repairing leaks in drainage and water pipes, and installing fixtures! I believe all work must be done neatly and to the home/business owner’s standards, no matter what.

Heating and Air Conditioning questions, answered by experts

A new HVAC system combines components to control indoor temperature and air quality. Features include a furnace or heat pump and an air conditioner or evaporator coil, depending on the climate requirements. It also involves a network of ductwork for air distribution, a thermostat for temperature regulation, and electrical connections. Air purifiers or humidifiers can be integrated to improve indoor air quality.

One of the fastest ways to unfreeze an AC unit is to turn off the unit and, if it’s warm outside, use the fan-only mode to help blow warmer air through the unit to speed up the defrosting process. While it may be tempting to use a hair dryer to defrost the air conditioner, that high heat can damage the coils.

After defrosting, if you can safely solve the issue with a fix like changing the filter, go ahead and do so. Otherwise, call in a pro before turning your AC back on.

Most HVAC companies recommend against setting your AC below 70 as it could freeze up the system and cause more problems. Regardless of how hot it is outside, there is generally a 20 degree difference between the outside and inside temperatures, so even if it’s 100 degrees outside, your AC will likely not be able to cool your home to 70 degrees.

Traditional central air conditioning systems require ductwork to circulate air throughout the home. Alternatively, you can add air conditioning with a mini-split ductless air conditioning system, which can be just as energy efficient as a central air conditioner. This type of system consists of two units–an outside unit that holds the compressor and condenser and an indoor unit that holds an air-handler. With multi-zone ductless systems, there are multiple indoor air handlers tied to a single outdoor compressor/condenser, allowing the system to cool multiple rooms.

It’s critical to use the right size AC for your space and not go too small or too big. If you purchase an undersized unit, it won’t properly cool your house, and it has to work harder to reach the optimal temperature. This will eventually wear your unit out. An oversized unit can spell trouble because it will turn off and on more frequently, which also wears out your AC unit. An oversized unit also causes humidity in the home.
