Residential Air Conditioning & Heating

What does “HVAC” mean?

HVAC is an abbreviation for heating, ventilation, and air conditioning. The term covers a broad range of air conditioning and heating systems including units, ducts, and filters.

Why do my ducts make sounds when the furnace starts?

This commonly indicates an issue of undersized ducts. It could also signify air flow that is too powerful for the existing ducts, which needs to be calibrated. Inspection by trained experts can help to determine the definitive cause.

Why would I want regular maintenance on my air conditioning or heating system?

Your home climate system is an investment. Allowing issues to develop and worsen can increase the eventual cost of repairs while reducing your home’s air quality. Regular annual maintenance helps you prepare for future upgrades or repairs while keeping peak performance in the meantime.

 

Commercial HVAC

How much are your estimates?

At R & S Mechanical, we provide 100% free on-site estimates with our trained and certified technicians. It’s of the utmost importance to us that we get you the right fit solution quickly without impeding your regular business operation.

Do I really need to have my condenser coil cleaned?

The benefits of regular cleaning can very easily outweigh the cost. Between improvement in the lifespan of your HVAC unit due to reduced heat and increased energy efficiency for the entire system you can recoup a dramatic cost savings in your utility bill.

What Is R-22 refrigerant?

This is an older variety of refrigerant which the EPA has established compliance measures to phase out due to its environmental impact. If your building retains an HVAC unit from prior to 2010, it likely utilizes R-22 refrigerant. R & S Mechanical’s Raleigh HVAC experts can advise you about optimal upgrade plans to keep your costs low.

    I have always been pleased with their service. They are quick to respond, even on weekends. I would definitely recommend them.

    Gail S.

    I had R&S come out to my house for the second time in the last couple of years to fix an issue with our heating system. they were able to show up quickly and promptly and fix the issue the same day. The folks I have dealt with at R&S have all been very friendly and helpful in explaining the two issues with our heater thus far. We’ve had very good experiences and would definitely recommend to other homeowners.
