Various HVAC tools.

Owning, or even sometimes renting, a home in Sierra Vista, AZ, requires general maintenance to keep your investment in working order. It’s really all about being prepared. Per Benjamin Franklin, “An ounce of prevention is worth a pound of cure.” Maintaining your home’s systems and appliances wards off emergency situations and costly repairs while extending your equipment’s life. Take the time and money to perform general maintenance on a regular basis. Many of the maintenance services require the knowledge, skills, and tools of a professional. During the maintenance or service call, our technician will make any necessary repairs and/or alert you of a possible situation. Call Arizona Comfort Systems to assist you in maintaining any of the following or to answer any questions you may have:

Furnace Maintenance

For furnaces and boilers, an annual service tune-up and cleaning is recommended, usually performed in the fall. The purpose is to keep your system running at top efficiency throughout the season, i.e., to keep you having heat when you need it. Our technician will check and clean all the connections, controls, sensors, drains, ignitor, ducts, pipes, burners, valves, motors, thermostat(s), and smoke/carbon-monoxide detectors, and instruct you on anything you could do between our service visits. As a rule of thumb, furnace filters need to be changed every three months or as needed, which is something you can do yourself with the correct filters.

Air Conditioner Maintenance

For air conditioners, an annual service tune-up and cleaning is recommended, usually performed in the spring. Our professional technician will check and clean the connections, coils, blower components, lines, refrigerant, drain, fuses, and thermostat(s), as well as lubricate all working parts. Maintenance you can do yourself between service visits is to remove any yard debris or vegetation from the top and sides of your outdoor air conditioner unit, as well as to keep it covered with an air conditioner cover or tarp in the winter.

Heat Pump Maintenance

For heat pumps, an annual service tune-up and cleaning is recommended, usually performed in the fall, same as furnaces and boilers. Our professional technician will check and clean ducts, filters, blower, indoor coil, ducts, refrigerant, electric terminals, connections, motors, and belts, as well as lubricate all working parts. Be sure to change or clean the filter every three months or as needed. You can also clean the outdoor coils whenever they seem dirty, and keep yard debris and vegetation away from the unit.

Whole-House Humidifier Maintenance

For whole-house humidifiers, an annual service tune-up and cleaning is recommended, usually performed at the same time as your furnace tune-up and cleaning. Our professionals include this maintenance along with the furnace appointment. Typically there isn’t much in the way of maintenance; however, our technician will change your humidifier pad and clean any mineral buildup you may have (in the case of hard water). Ask our technician to show you how to dissolve the buildup on your own every few months to keep your humidifier working at top efficiency.

Air-Filtration System Maintenance

For air-filtration systems, regular maintenance is something your can perform on your own. Maintenance on an air-filtration system usually just means changing or cleaning the filter every three to nine months. But you should check with the manufacturer’s specific recommendations. Changing or cleaning your filter on a regular basis will ensure the best filtration for your home as well as extend the life of the system. If you need any assistance or would like to install an air-filtration system, feel free to talk with one of our professionals at Arizona Comfort Systems.

Water Heater Maintenance

For water heaters, an annual inspection and service is recommended, usually included in your annual plumbing inspection (any required service would be separate). Either have one of our professional plumbers perform the required maintenance, especially if you’re uncomfortable doing it yourself, or do it yourself. To keep your water heater running efficiently, you want to check the pressure valve, check the anode rod, flush the tank (due to sediment buildup), adjust the temperature (if needed), and insulate the pipes and tank (if needed). Once again, one of our professional plumbers can easily do this service for you to help in extending the life of your water heater.

Gas Fireplace Maintenance

For gas fireplaces, an annual inspection and service is recommended, usually performed in the fall. Dust, dirt, and insects can clog and infect your orifices and burner ports, affecting your unit’s ability to burn. Also, parts wear out allowing dangerous carbon monoxide to leak into your home. Having your fireplace inspected and cleaned on an annual basis will ensure years of beautiful and warm fires when you want them.

During the inspection and service, our professional technician will check and clean the inside combustion chamber, pilot, burners, logs, safety switches, glass doors or lens, wiring, and gas valve. On a monthly basis, you could inspect and service your fireplace by cleaning the glass doors and checking their bolts for door stability, check the glass-door or exterior gasket for cracks or missing pieces, and check the outside vent for debris/dirt and for tears or damage to the vent kit.

At Arizona Comfort Systems, we’re here to to assist you in maintaining your home’s systems or to answer any of your questions about maintenance. Keeping your equipment in good working order allows you peace of mind to know they’ll be there when you need them. It also makes good financial sense to keep equipment serviced to help extend their life spans. Here in Sierra Vista, AZ, call us at 520-415-5681 to make an appointment now.

“Eric D. Did maintenance on both of our systems. Then because of distancing the office called me but I had Eric explain things to me so I could understand better but when he left after fixing one system he did not let me know other wise I would have given 5
stars. I waited to do my stuff while he was here but he should have leg me know he was done.” – Kathryn G.

He keeps my little heat pump in tip top condition

“I have shared many, many times with you the excellent service my heat pump has received from Raymond. Raymond knows and "understands" this heat pump and my disability as well. He keeps my little heat pump in tip top condition.”

– Janet W.

Eric was great

“Eric was great. The only reason you didn't get 5 stars was that the appointment was for noon and he was understandably 3 hours later due to another customer's emergency. But to your credit I was notified and given the option to reschedule.”

– Don S.

Top notch beginning to end

“The whole experience from scheduling to completion of the ac system check went smooth. Eric was punctual, he performed his check and cleaning of the system in about about an hour, he cleaned up when done, and then described everything he had done and what condition the system was in. Top notch beginning to end.”

– Mike C.

We will have Robert come back in November for a next service

“Robert came out today and serviced our 3 AC’s and 2 water heaters. I had requested Robert come out because he had been out to the house before on a service call and did a super job. He is very professional and knowledgeable and by watching him, he obviously takes a lot of pride in the work he does. We will have Robert come back in November for a next service.”
