"We use Laury for repair and maintenance of our heating and cooling units for our rental properties and each time we need something done, the staff at Laury never cease to provide quality service. The technicians are always knowledgeable, thorough, courteous and pleasant. We recently had an HVAC system installed in one of our units and the home is rather large and is over 100 years old and there was not a whole lot of empty space to work with. The guys at Laury were able to install the system and all of the duct work and components involved neatly with the age and make-up of the home in-mind. They were pleasant throughout the entire installation which took almost a week. They were always on time and always communicated the process with us. Laury is a trusted business with many years of experience behind them. Prices are also extremely reasonable given the cost of services right now. Warren you are the man!"

"I am a retired HVAC SELF EMPLOYED Contractor for over 25 years. . Dave and Jeremy did a fantastic and professional job on installing the mini-split heat pump. Communication between the office and my schedule was painless. Jen was accommodating in every way possible. It is a pleasure to see a company like Robinson Mechanical putting the customer first. As I mentioned, I am a retired HVAC Contractor, and will continue on using Robinson Mechanical. I could not have done the job better if I installed it myself. You will not go wrong hiring this Company."

"Ed & Cris arrived exactly at 1PM when they said. They hauled in a heavy suction vacuum and attached to both supply and then return lines. Showed me the dirt collected in the first stage of the cleaner. Both men worked hard and did an excellent job. Was not ready for the dust throughout the house but they did warn me of it. We just finished a dirty tile job so the vent cleaning was a natural first. This is my second Angie's list contractor and we are contented.

"Heating Specialties workers arrived on time and were very professional. The crew leader reviewed all of the work with me so I understood everything about my new AC system and how it worked. The were very respectful of my property and cleaned every work area before leaving. They trained my on how to program the new theromstats and made sure the I knew how to override the system should I ever have an issue with the zoned AC. I will use them for all of my heating/air conditioning needs for this point on. This is a five star operation."

"George was prompt and seemed very concerned about providing top notch service. He did a great job of explaining how my HVAC system was supposed to work and how the servicing would correct the problem. I also appreciate that he didn’t try to pressure me into more expensive solutions."

Heating and Air Conditioning FAQs, answered by experts

A home AC unit provides anywhere from one-half to five tons of cooling and requires approximately two to four pounds of refrigerant per ton of cooling. At approximately five to 10 minutes to fill one pound of refrigerant, a home that requires three tons of cooling will take about six to 12 pounds of refrigerant and approximately 30 minutes to two hours to completely recharge the unit.

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.

You should use a breathable, weather-resistant cover with ventilation. It can be a top cover or a full cover that has mesh to allow airflow. A full, non-breathable cover can cause moisture to build up, leading to rust, frozen parts, and corrosion. A full cover also attracts unwanted critters, such as mice, that can damage the wiring and your unit. If you need to protect your AC unit from falling icicles, choose a sturdy top cover or piece of wood that prevents icicles from damaging your unit.

HVAC pros recommend that you replace your AC filter every one to three months to maintain optimal indoor air quality and ensure your HVAC system operates efficiently. However, factors such as filter type, household size, and environmental conditions may influence the frequency of replacement. Regular filter changes help prevent debris buildup, maintain airflow, and prolong the life span of your air conditioning unit.

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.
