"I have been using locally owned and operated Admiral Heating & Air Conditioning, Inc. for a couple of years now after needing to purchase a new unit. They are incredibly affordable, professional, and knowledgeable. They always walk us through to understand what work needs to be performed before doing soâ knowing that their technicians have over 24 years of experience and continuous training from electronics troubleshooting to airflow problems and solutions is comforting. They are also available during evening and weekend hours and never charge extra for that, which came in handy a couple of years ago when our unit broke, and we needed to find a company fast to replace it. I cannot recommend them enough to all of my neighbors."

"I must say I was blown away by the difference this service made to my home and family. It’s a night and day difference in our home now in regards to our air quality. We did this 5 years ago and had little difference in results. This time around we contacted Kevin because a friend referred him and they where on time, professional and respectful of our space. His knowledge and attention to detail alone made me feel comfortable and now the results reflect that. He’s my go to go guy from now on for me, my family and friends. Best decision ever!!"

"I was first impressed when the owner, Mr Rankin , answered the phone within 2 rings. After explaining what i was looking for , Mr Rankin explained in detail what his company could do as far as duct cleaning of my HVAC system. He was forthright and knowledgeable and answered all my questions regarding his company's reputation and experience. Immediately after our conversation he emailed me a very detailed quite and his company insurance documentation. My appointment was made., and he texted me the names of the technicians. They arrived on time, equipped with booties to wear thru out the house. The work performed took about 4 hours from start to finish. Mr Rankin's techs were extremely polite and very respectful . They also took their tome cleaning up after themselves. We have noticed an immediate improvement, so much so i was considering replacing HVAC unit before i met Mr Rankin. Now the unit is working as it should and my entire hone is very comfotable. I am so happy with the results and if you are considering getting your HVAC ductwork cleaned and sealed , I would highly recommend this company. Good to see great customer service. Thankyou to Mr Rankin and his team of professional technicians"

Heating and Air Conditioning FAQs, answered by experts

Swamp coolers cost approximately 50 percent less to install than central air conditioners and cost less to run. Operation costs depend on the size of the unit and home, your climate, utility rates in your area, and the system’s efficiency. Swamp coolers use 15 to 35 percent less power than air conditioners.

Whether an HVAC damper should be open or closed depends on the season, the zone it controls, and the temperature in that zone. In the summer, open upstairs dampers and close lower-level dampers to get the most efficient cooling possible. In the winter, do the opposite. Cool air will naturally flow down to lower levels, while warm air will rise. This keeps your system from working harder and helps prevent common AC problems.

Modern AC leak sealants work as a temporary measure to stop refrigerant leaks. You can purchase them at most home improvement stores or on online. When using an AC leak sealant, keep in mind that it’s only a temporary solution, so you’ll still need to hire a pro to install a replacement part as soon as possible.

You need to know the square footage of your home first. Multiply that number by 20, which will get you the BTUs (British Thermal Units) needed to cool your home efficiently. Homes up to 1,000 square feet usually need a 1.5-ton unit; homes 1,000 to 1,200 square feet usually need a 1.75-ton unit, and homes 1,200 to 1,400 square feet usually need a 1.9-ton unit. Talk to a local pro for more specific advice on your home. 

It all depends on the unit’s SEER (seasonal energy efficiency ratio). A higher SEER rating means better efficiency and lower costs for your energy bills. 

Take a look at the product you’re considering purchasing and compare it to other models to decide which one is affordable upfront but will keep your energy costs low over time.
