FAQs

Common Questions About Our Cooling Services

What cooling services does Plumbing Masters offer?

Plumbing Masters handles the full range of home cooling work. We repair and replace air conditioners, install new AC systems, perform seasonal maintenance and tune-ups, add indoor air quality solutions like filters, purifiers and humidity controls, and install or upgrade thermostats. Whether your system needs a small fix or a full upgrade, we explain your options in plain terms so you can choose what fits your home.

How do I know if I need AC repair, a tune-up or a new system?

If your air conditioner runs but cools poorly, makes new noises or shuts off early, start with a repair visit. If it works fine and you want it ready for summer, book a tune-up. If it is older, needs frequent repairs or cannot keep the house comfortable on hot days, replacement may make more sense. Not sure? Plumbing Masters will inspect it and recommend the right next step.

Can one company handle both my plumbing and my air conditioning?

Yes. Plumbing Masters is a family-owned plumbing and HVAC company led by Master Plumbers since 1984. The same team that handles your plumbing repairs also takes care of AC repair, installation and maintenance, so you have one trusted contact for the systems that keep your home running. It saves you from juggling separate contractors and repeating your home’s history to each one.

Can cooling upgrades improve comfort beyond colder air?

Yes. Comfort also depends on humidity, air cleanliness and how well your system is controlled. A dehumidifier can make summer air feel less sticky, upgraded filtration and purifiers cut down on dust and odors, and a smart or programmable thermostat keeps temperatures steady around your schedule. We look at how your home feels, not just the temperature, and recommend the upgrades that fit your system.

What can I do to help my air conditioner run efficiently?

Check the air filter monthly during cooling season, keep supply and return vents open and unblocked, and clear leaves, grass and debris from around the outdoor unit. Close blinds on sunny afternoons and avoid big temperature swings on the thermostat. Pair those habits with a yearly professional tune-up from Plumbing Masters and your system will work less to keep your home comfortable.

 Trustindex verifies that the original source of the review is Google. Needed to have the kitchen drain line cleared for the first time after 30 years in the house.  Was able to schedule service promptly, which was handled professionally and competently.  I think the price for the drain cleaning was reasonable, though it is a bit higher than what is seen sometimes in online advertising from other companies.  Have been using plumbing master’s for many years and things are always handled competently by respectful and knowledgeable professionals.

 Trustindex verifies that the original source of the review is Google. Yesterday I reached out to get on schedule to replace my outdoor spigot. Lucy was able to fit me in today for repair. Lorenzo was amazing! He got me fixed up in no time & walked me through steps to prevent line from busting/freezing next season! Shout out to Jared & Brian from previous repairs! Every experience I’ve had with Plumbing Masters has been great! Highly recommend!
