I really prefer our HVAC company. When our fiance plus I first moved to this area, these people were recommended by most of our neighbors. I recognize that most of the neighbors in our area use the same HVAC company. The HVAC workers were quick to propose their HVAC method maintenance plans also. They have a few unusual kinds, 1 for basic HVAC method tune-ups plus maintenance, plus a few others for more serious HVAC method maintenance. With the more upscale plans, you can get your ductwork cleaning taken care of plus even have air filter swings every numerous weeks. They suggest using the high quality air filters that are wonderful for people with flu symptoms. They must be changed everything 3 weeks plus they work great. I did decide to go for the basis HVAC method maintenance plan. I think the basic is good for us because I can take care of our own air filter swings. I guess what kind of air filters to get, plus I do prefer to get the high quality air filters. With all the savings I am getting with the HVAC method maintenance plan, I can absolutely afford the more upscale air filters! I prefer the quality air filters because it keeps the air quality nice. I considered getting the plan that covers the ductwork cleaning as well because I realize how important that is, but I figured I could just get that done every other year. Having the ductwork cleaned is great for air quality, but it’s not as important as other types of HVAC method maintenance.
