"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!"

"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

The average cost to replace or install a new HVAC system is around $7,500. However, the price can range from $5,000 to $12,500, depending on factors like the size of your home, the type and brand of the unit, and your specific heating and cooling needs. If you only need to replace certain components, the cost will be lower; for example, a new AC unit can cost between $2,200 and $5,500, while a new furnace costs $3,200 to $6,000. If additional work like new ductwork is required, the total cost could be as high as $22,000. It's best to contact a local HVAC company for an accurate quote.

They can, but it’s not as common. Window AC units are much smaller than whole-house systems and less likely to develop refrigerant leaks or similar issues. As a result, you will rarely need to add a new refrigerant, limiting overcharging problems. However, it’s still important to leave refrigerant management in the hands of professionals when window units need work.

There are several common types of HVAC systems that you may have, including split systems, hybrid HVAC, duct-free systems, packaged heating and air, geothermal heating, or even portable units for heating or cooling. If you aren’t sure which type is in your home or are looking to install something different, you should consult an HVAC pro to determine which option is right for your heating and cooling needs.

Vents may blow air even though the air conditioning system is off because of the pressure difference between indoor and outdoor air or drafts from leaky ducts. Check for leaks or drafts in the ductwork or around windows and doors.

No, you should not attempt to replace an AC evaporator coil yourself. This is a complex task that must be performed by a licensed HVAC technician. The process involves handling hazardous and flammable refrigerants, which poses significant safety risks. Attempting a DIY replacement can also cause further damage to your HVAC system and will likely void its warranty. It is necessary to hire a local AC repair professional for this job.
