"Moore services my HVAC every six months. The crew that came out for my recent call, have been to my house before. Nice to see familiar faces. My main sewage drain clogged in front of my house at 4:50 pm. I called Moore and you’re team came out in 30 minutes. The crew had it unclogged at 5:40 pm. I couldn’t believe it. I was considering taking my family to a hotel. With that clog, staying in the house was not possible. You guys are awesome!!!"

"We had a totally broken HVAC system in our 30 year old house. They came in and fixed it in two days. The guys were very friendly and answered our questions. Our original salesperson was knowledgeable and respectful considering the state of our equipment at that time. Now we have heat for the rest of the Winter and AC for next year. Thank you!"

"Tony was knowledgeable and explained the step by step service to be performed and why it was important to a heating system for efficiency and general maintenance. I thought the price was not inexpensive. However, I chose Ramirex Duct Cleaning due to Tony's presentation. Tony and his 2 assistants were neat, efficient and careful. My 24 year old furnace blade system and 10 vents were cleaned as well as the dryer and vent system within 3 years. Tony took before and after pictures of each phase of the operation which was impressive."

Heating and Air Conditioning questions, answered by experts

It is possible to add air conditioning to an older home, but it can be very expensive to do so. Expect to pay anywhere from $6,000 to $17,000 or more for the ductwork and AC unit. You’ll also have to hack into the home’s walls and ceilings to add ductwork, which can impact the aesthetics of an old home.

As a general rule, you should have your HVAC system professionally serviced at least once a year, though it's best to follow the manufacturer's specific recommendations. Many experts suggest twice-yearly maintenance: once in the spring for the cooling system and once in the fall for the heating system. This is especially recommended for older units, systems with recurring issues, or heat pumps that provide both heating and cooling. Regular service, which can cost between $100 and $550, keeps the system running efficiently, helps prevent costly future repairs, and saves money on utility bills.

Most AC repair technicians will take between two and six hours to carry out repairs, depending on the work needed and the accessibility of the unit. For example, recharging refrigerant lines should take one to two hours to service, while replacing a compressor, blower fan, or other major components can take five to eight hours. You can ask your AC repair technician how long they expect the job to take, but just in case, you should plan on being home and available for most of the day.

A new HVAC system can increase your home's value by about 5% to 7%, which can translate to an added value of $2,500 to $3,000. The return on investment (ROI) can be around 30%, especially if you upgrade the entire system, including ductwork and insulation. Adding modern features like a smart thermostat can further increase your home’s value by making the heating and cooling systems more efficient and convenient. However, since a new unit can cost $10,000 or more to install, it's important to weigh the upfront cost against the potential increase in home value. For a specific assessment, it's best to consult a local AC installer.

A blocked return air vent can cause your HVAC system to work much harder and, therefore, less efficiently. The result is higher utility bills and poorer air quality. A blocked return air vent can also cause unpleasant dust, dander, and odors to linger in your home’s air.
